Ember Data Factory Guy

Feel the thrill and enjoyment of testing when using Factories instead of Fixtures. Factories simplify the process of testing, making you more efficient and your tests more readable.

NEW starting with v3.8

jquery is no longer required and fetch adapter is used with ember-data
you can still use jquery if you want to
if you are addon author using factory guy set up your application adapter like this

NEW starting with v3.2.1

You can setup data AND links for your async relationship Check it out

NEW You can use factory guy in ember-twiddle

Using Scenarios

NEW If using new style of ember-qunit acceptance tests with setupApplicationTest check out demo here: user-view-test.js:

NEW starting with v2.13.27

get attributes for factory defined models with attributesFor

NEW starting with v2.13.24

manualSetup streamlined to manualSetup(this)

NEW and Improved starting with v2.13.22

Traits can be functions Check it out

Older but still fun things

Support for ember-data-model-fragment usage is baked in since v2.5.0
Support for ember-django-adapter usage is fried in since v2.6.1
Support for adding meta data to payloads for use with ember-infinity ie. => pagination
Support for adding headers to payloads

Why is FactoryGuy so awesome

Since you're using ember data, you don't need to create any ORM like things
You don't need to add any files to recreate the relationships in your models
Any custom methods like: serialize / serializeAttribute / keyForAttribute etc... in a serializer will be used automatically
If you set up custom methods like: buildURL / urlForFindRecord in an adapter, they will be used automatically
You have no config file with tons of spew, because you declare all the mocks and make everything declaratively in the test
You can push models and their complex relationships directly to the store

How it works

You create factories for your models.
- put them in the tests/factories directory
Use these factories to create models for your tests
- you can make records that persist in the store
- or you can build a json payload used for mocking an ajax call's payload

Installation

ember install ember-data-factory-guy ( ember-data-1.13.5+ )
ember install [email protected] ( ember-data-1.13.0 + )
ember install [email protected] ( ember-data-1.0.0-beta.19.1 )
ember install [email protected] ( ember-data-1.0.0-beta.16.1 )

Upgrading

remove ember-data-factory-guy from package.json
npm prune
ember install ember-data-factory-guy ( for the latest release )

Setup

In the following examples, assume the models look like this:

  // standard models
  class User extends Model {
    @attr('string')     name
    @attr('string')     style
    @hasMany('project') projects
    @hasMany('hat', {polymorphic: true})  hats
  }

  class Project extends Model {
    @attr('string')     title
    @belongsTo('user')  user
  }

  // polymorphic models
  class Hat extends Model {
    @attr('string')     type
    @belongsTo('user')  user
  }

  class BigHat extends Hat {};
  class SmallHat extends Hat {};

Defining Factories

A factory has a name and a set of attributes.
The name should match the model type name. So, for the model User, the factory name would be user
Create factory files in the tests/factories directory.
Can use generators to create the outline of a factory file: ember generate factory user This will create a factory in a file named user.js in the tests/factories directory.

Standard models

Sample full blown factory: user.js
Brief sample of a factory definition:


  // file tests/factories/user.js
  import FactoryGuy from 'ember-data-factory-guy';

  FactoryGuy.define('user', {
    // Put default 'user' attributes in the default section
    default: {
      style: 'normal',
      name: 'Dude'
    },
    // Create a named 'user' with custom attributes
    admin: {
      style: 'super',
      name: 'Admin'
    }
  });

If you are using an attribute named type and this is not a polymorphic model, use the option polymorphic: false in your definition

// file: tests/factories/cat.js
FactoryGuy.define('cat', {
  polymorphic: false, // manually flag this model as NOT polymorphic
  default: {
    // usually, an attribute named 'type' is for polymorphic models, but the defenition
    // is set as NOT polymorphic, which allows this type to work as attibute
    type: 'Cute',
    name: (f)=> `Cat ${f.id}`
  }
});

Polymorphic models

Define each polymorphic model in its own typed definition
The attribute named type is used to hold the model name
May want to extend the parent factory here (see extending other definitions)


  // file tests/factories/small-hat.js
  import FactoryGuy from 'ember-data-factory-guy';

  FactoryGuy.define('small-hat', {
    default: {
      type: 'SmallHat'
    }
  })

  // file tests/factories/big-hat.js
  import FactoryGuy from 'ember-data-factory-guy';

  FactoryGuy.define('big-hat', {
    default: {
      type: 'BigHat'
    }
  })

In other words, don't do this:

  // file tests/factories/hat.js
  import FactoryGuy from 'ember-data-factory-guy';

  FactoryGuy.define('hat', {
    default: {},
    small-hat: {
      type: 'SmallHat'
    },
    big-hat: {
      type: 'BigHat'
    }
  })

Sequences

For generating unique attribute values.
Can be defined:
- In the model definition's sequences hash
- Inline on the attribute
Values are generated by calling FactoryGuy.generate

Declaring sequences in sequences hash


  FactoryGuy.define('user', {
    sequences: {
      userName: (num)=> `User${num}`
    },

    default: {
      // use the 'userName' sequence for this attribute
      name: FactoryGuy.generate('userName')
    }
  });

  let first = FactoryGuy.build('user');
  first.get('name') // => 'User1'

  let second = FactoryGuy.make('user');
  second.get('name') // => 'User2'

Declaring an inline sequence on attribute


  FactoryGuy.define('project', {
    special_project: {
      title: FactoryGuy.generate((num)=> `Project #${num}`)
    },
  });

  let json = FactoryGuy.build('special_project');
  json.get('title') // => 'Project #1'

  let project = FactoryGuy.make('special_project');
  project.get('title') // => 'Project #2'

Inline Functions

Declare a function for an attribute
- The fixture is passed as parameter so you can reference all other attributes, even id


  FactoryGuy.define('user', {
    default: {
      // Don't need the userName sequence, since the id is almost
      // always a sequential number, and you can use that.
      // f is the fixture being built as the moment for this factory
      // definition, which has the id available
      name: (f)=> `User${f.id}`
    },
    traits: {
      boring: {
        style: (f)=> `${f.id} boring`
      },
      funny: {
        style: (f)=> `funny ${f.name}`
      }
    }
  });

  let json = FactoryGuy.build('user', 'funny');
  json.get('name') // => 'User1'
  json.get('style') // => 'funny User1'

  let user = FactoryGuy.make('user', 'boring');
  user.get('id') // => 2
  user.get('style') // => '2 boring'

Note the style attribute was built from a function which depends on the name and the name is a generated attribute from a sequence function

Traits

Used with attributesFor , build/buildList , make/makeList
For grouping attributes together
Can use one or more traits
Each trait overrides any values defined in traits before it in the argument list
traits can be functions ( this is mega powerful )


  FactoryGuy.define('user', {
    traits: {
      big: { name: 'Big Guy' },
      friendly: { style: 'Friendly' },
      bfg: { name: 'Big Friendly Giant', style: 'Friendly' }
    }
  });

  let user = FactoryGuy.make('user', 'big', 'friendly');
  user.get('name') // => 'Big Guy'
  user.get('style') // => 'Friendly'

  let giant = FactoryGuy.make('user', 'big', 'bfg');
  user.get('name') // => 'Big Friendly Giant' - name defined in the 'bfg' trait overrides the name defined in the 'big' trait
  user.get('style') // => 'Friendly'

You can still pass in a hash of options when using traits. This hash of attributes will override any trait attributes or default attributes


  let user = FactoryGuy.make('user', 'big', 'friendly', {name: 'Dave'});
  user.get('name') // => 'Dave'
  user.get('style') // => 'Friendly'

Using traits as functions

import FactoryGuy from 'ember-data-factory-guy';

FactoryGuy.define("project", {
  default: {
    title: (f) => `Project ${f.id}`
  },
  traits: {
    // this trait is a function
    // note that the fixure is passed in that will have
    // default attributes like id at a minimum and in this
    // case also a title ( `Project 1` ) which is default
    medium: (f) => {
      f.title = `Medium Project ${f.id}`
    },
    goofy: (f) => {
      f.title = `Goofy ${f.title}`
    }
    withUser: (f) => {
      // NOTE: you're not using FactoryGuy.belongsTo as you would
      // normally in a fixture definition
      f.user = FactoryGuy.make('user')
    }
  }
});

So, when you make / build a project like:

let project =  make('project', 'medium');
project.get('title'); //=> 'Medium Project 1'

let project2 =  build('project', 'goofy');
project2.get('title'); //=> 'Goofy Project 2'

let project3 =  build('project', 'withUser');
project3.get('user.name'); //=> 'User 1'

Your trait function assigns the title as you described in the function

Associations

Can setup belongsTo or hasMany associations in factory definitions
- As inline attribute definition
- With traits
- as links for async relationships
Can setup belongsTo or hasMany associations manually
- With FactoryGuy.build/FactoryGuy.buildList and FactoryGuy.make/FactoryGuy.makeList
  - Can compose relationships to any level
- When setting up manually do not mix build and make - you either build JSON in every levels of associations or make objects. build is taking serializer into account for every model which means that output from build might be different than expected input defined in factory in make.
Special tips for links

Setup belongsTo associations in Factory Definitions

using traits are the best practice

  FactoryGuy.define('project', {

    traits: {
      withUser: { user: {} },
      withAdmin: { user: FactoryGuy.belongsTo('user', 'admin') },
      withManagerLink(f) { // f is the fixture being created
        f.links = {manager: `/projects/${f.id}/manager`}
      }
    }
  });

  let user = make('project', 'withUser');
  project.get('user').toJSON({includeId: true}) // => {id:1, name: 'Dude', style: 'normal'}

  user = make('user', 'withManagerLink');
  user.belongsTo('manager').link(); // => "/projects/1/manager"

Setup belongsTo associations manually

See FactoryGuy.build/FactoryGuy.buildList for more ideas

  let user = make('user');
  let project = make('project', {user});

  project.get('user').toJSON({includeId: true}) // => {id:1, name: 'Dude', style: 'normal'}

Note that though you are setting the 'user' belongsTo association on a project, the reverse user hasMany 'projects' association is being setup for you on the user ( for both manual and factory defined belongsTo associations ) as well

  user.get('projects.length') // => 1

Setup hasMany associations in the Factory Definition

using traits are the best practice
Do not create hasMany records via the default section of the factory definition. Prefer traits to set up such associations. Creating them via the default section is known to cause some undefined behavior when using the makeNew API.


  FactoryGuy.define('user', {
    traits: {
      withProjects: {
        projects: FactoryGuy.hasMany('project', 2)
      },
      withPropertiesLink(f) { // f is the fixture being created
        f.links = {properties: `/users/${f.id}/properties`}
      }
    }
  });

  let user = make('user', 'withProjects');
  user.get('projects.length') // => 2

  user = make('user', 'withPropertiesLink');
  user.hasMany('properties').link(); // => "/users/1/properties"

You could also setup a custom named user definition:

  FactoryGuy.define('user', {

    userWithProjects: { projects: FactoryGuy.hasMany('project', 2) }

  });

  let user = make('userWithProjects');
  user.get('projects.length') // => 2

Setup hasMany associations manually

See FactoryGuy.build/FactoryGuy.makeList for more ideas

  let project1 = make('project');
  let project2 = make('project');
  let user = make('user', {projects: [project1, project2]});
  user.get('projects.length') // => 2

  // or
  let projects = makeList('project', 2);
  let user = make('user', {projects});
  user.get('projects.length') // => 2

Note that though you are setting the 'projects' hasMany association on a user, the reverse 'user' belongsTo association is being setup for you on the project ( for both manual and factory defined hasMany associations ) as well

  projects.get('firstObject.user')  // => user

Special tips for links

The links syntax changed as of ( v3.2.1 )
- What you see below is the new syntax
You can setup data AND links for your async relationship
Need special care with multiple traits setting links


  FactoryGuy.define('user', {
    traits: {
      withCompanyLink(f): {
        // since you can assign many different links with different traits,
        // you should Object.assign so that you add to the links hash rather
        // than set it directly ( assuming you want to use this feature )
        f.links = Object.assign({company: `/users/${f.id}/company`}, f.links);
      },
      withPropertiesLink(f) {
        f.links = Object.assign({properties: `/users/${f.id}/properties`}, f.links);
      }
    }
  });

  // setting links with traits
  let company = make('company')
  let user = make('user', 'withCompanyLink', 'withPropertiesLink', {company});
  user.hasMany('properties').link(); // => "/users/1/properties"
  user.belongsTo('company').link(); // => "/users/1/company"
  // the company async relationship has a company AND link to fetch it again
  // when you reload that relationship
  user.get('company.content') // => company
  user.belongsTo('company').reload() // would use that link "/users/1/company" to reload company

  // you can also set traits with your build/buildList/make/makeList options
  user = make('user', {links: {properties: '/users/1/properties'}});

Extending Other Definitions

Extending another definition will inherit these sections:
- sequences
- traits
- default attributes
Inheritance is fine grained, so in each section, any attribute that is local will take precedence over an inherited one. So you can override some attributes in the default section ( for example ), and inherit the rest

There is a sample Factory using inheritance here: big-group.js

Transient Attributes

Use transient attributes to build a fixture
- Pass in any attribute you like to build a fixture
- Usually helps you to build some other attribute
- These attributes will be removed when fixture is done building
Can be used in make/makeList/build/buildList

Let's say you have a model and a factory like this:


  // app/models/dog.js
  import Model from 'ember-data/model';
  import attr from 'ember-data/attr';

  export default class Dog extends Model{
    @attr('string') dogNumber
    @attr('string') sound
  }

  // tests/factories/dog.js
  import FactoryGuy from 'ember-data-factory-guy';

  const defaultVolume = "Normal";

  FactoryGuy.define('dog', {
    default: {
      dogNumber: (f)=> `Dog${f.id}`,
      sound: (f) => `${f.volume || defaultVolume} Woof`
    },
  });

Then to build the fixture:

  let dog2 = build('dog', { volume: 'Soft' });

  dog2.get('sound'); //=> `Soft Woof`

Callbacks

afterMake
- Uses transient attributes
- Unfortunately the model will fire 'onload' event before this afterMake is called.
  - So all data will not be setup by then if you rely on afterMake to finish by the time onload is called.
  - In this case, just use transient attributes without the afterMake

Assuming the factory-guy model definition defines afterMake function:

  FactoryGuy.define('property', {
    default: {
      name: 'Silly property'
    },

    // optionally set transient attributes, that will be passed in to afterMake function
    transient: {
      for_sale: true
    },

    // The attributes passed to after make will include any optional attributes you
    // passed in to make, and the transient attributes defined in this definition
    afterMake: function(model, attributes) {
      if (attributes.for_sale) {
        model.set('name', model.get('name') + '(FOR SALE)');
      }
    }
  }

You would use this to make models like:

  run(function () {

    let property = FactoryGuy.make('property');
    property.get('name'); // => 'Silly property(FOR SALE)')

    let property = FactoryGuy.make('property', {for_sale: false});
    property.get('name'); // => 'Silly property')
  });

Remember to import the run function with import { run } from "@ember/runloop";

Using Factories

FactoryGuy.attributesFor
- returns attributes ( for now no relationship info )
FactoryGuy.make
- push model instances into store
FactoryGuy.makeNew
- Create a new model instance but doesn't load it to the store
FactoryGuy.makeList
- Loads zero to many model instances into the store
FactoryGuy.build
- Builds json in accordance with the adapter's specifications
  - RESTAdapter (assume this adapter being used in most of the following examples)
  - ActiveModelAdapter
  - JSONAPIAdapter
  - DrfAdapter (Ember Django Adapter)
FactoryGuy.buildList
- Builds json with a list of zero or more items in accordance with the adapter's specifications
Can override default attributes by passing in an object of options
Can add attributes or relationships with traits
Can compose relationships
- By passing in other objects you've made with build/buildList or make/makeList
Can setup links for async relationships with build/buildList or make/makeList

`FactoryGuy.attributesFor`

nice way to get attibutes for a factory without making a model or payload
same arguments as make/build
no id is returned
no relationship info returned ( yet )


  import { attributesFor } from 'ember-data-factory-guy';

  // make a user with certain traits and options
  attributesFor('user', 'silly', {name: 'Fred'}); // => { name: 'Fred', style: 'silly'}

`FactoryGuy.make`

Loads a model instance into the store
makes a fragment hash ( if it is a model fragment )
can compose relationships with other FactoryGuy.make/FactoryGuy.makeList
can add relationship links to payload


  import { make } from 'ember-data-factory-guy';

  // make a user with the default attributes in user factory
  let user = make('user');
  user.toJSON({includeId: true}); // => {id: 1, name: 'User1', style: 'normal'}

  // make a user with the default attributes plus those defined as 'admin' in the user factory
  let user = make('admin');
  user.toJSON({includeId: true}); // => {id: 2, name: 'Admin', style: 'super'}

  // make a user with the default attributes plus these extra attributes provided in the optional hash
  let user = make('user', {name: 'Fred'});
  user.toJSON({includeId: true}); // => {id: 3, name: 'Fred', style: 'normal'}

  // make an 'admin' user with these extra attributes
  let user = make('admin', {name: 'Fred'});
  user.toJSON({includeId: true}); // => {id: 4, name: 'Fred', style: 'super'}

  // make a user with a trait ('silly') plus these extra attributes provided in the optional hash
  let user = make('user', 'silly', {name: 'Fred'});
  user.toJSON({includeId: true}); // => {id: 5, name: 'Fred', style: 'silly'}

  // make a user with a hats relationship ( hasMany ) composed of pre-made hats
  let hat1 = make('big-hat');
  let hat2 = make('big-hat');
  let user = make('user', {hats: [hat1, hat2]});
  user.toJSON({includeId: true})
  // => {id: 6, name: 'User2', style: 'normal', hats: [{id:1, type:"big_hat"},{id:1, type:"big_hat"}]}
  // note that hats are polymorphic. if they weren't, the hats array would be a list of ids: [1,2]

  // make a user with a company relationship ( belongsTo ) composed of a pre-made company
  let company = make('company');
  let user = make('user', {company: company});
  user.toJSON({includeId: true})  // => {id: 7, name: 'User3', style: 'normal', company: 1}

  // make user with links to async hasMany properties
  let user = make('user', {properties: {links: '/users/1/properties'}});

  // make user with links to async belongsTo company
  let user = make('user', {company: {links: '/users/1/company'}});

  // for model fragments you get an object
  let object = make('name'); // => {firstName: 'Boba', lastName: 'Fett'}

`FactoryGuy.makeNew`

Same api as FactoryGuy.make
- except that the model will be a newly created record with no id

`FactoryGuy.makeList`

check out (user factory): to see 'bob' user and 'with_car' trait

Usage:


  import { make, makeList } from 'ember-data-factory-guy';

  // Let's say bob is a named type in the user factory
  makeList('user', 'bob') // makes 0 bob's

  makeList('user', 'bob', 2) // makes 2 bob's

  makeList('user', 'bob', 2, 'with_car', {name: "Dude"})
  // makes 2 bob users with the 'with_car' trait and name of "Dude"
  // In other words, applies the traits and options to every bob made

  makeList('user', 'bob', 'with_car', ['with_car', {name: "Dude"}])
  // makes 2 users with bob attributes. The first also has the 'with_car' trait and the
  // second has the 'with_car' trait and name of "Dude", so you get 2 different users

`FactoryGuy.build`

for building json that you can pass as json payload in acceptance tests
takes the same arguments as FactoryGuy.make
can compose relationships with other FactoryGuy.build/FactoryGuy.buildList payloads
can add relationship links to payload
takes serializer for model into consideration
to inspect the json use the get method
use the add method
- to include extra sideloaded data to the payload
- to include meta data
- REMEMBER, all relationships will be automatically sideloaded, so you don't need to add them with the add() method

Usage:


  import { build, buildList } from 'ember-data-factory-guy';

  // build a basic user with the default attributes from the user factory
  let json = build('user');
  json.get() // => {id: 1, name: 'User1', style: 'normal'}

  // build a user with the default attributes plus those defined as 'admin' in the user factory
  let json = build('admin');
  json.get() // => {id: 2, name: 'Admin', style: 'super'}

  // build a user with the default attributes with extra attributes
  let json = build('user', {name: 'Fred'});
  json.get() // => {id: 3, name: 'Fred', style: 'normal'}

  // build the admin defined user with extra attributes
  let json = build('admin', {name: 'Fred'});
  json.get() // => {id: 4, name: 'Fred', style: 'super'}

  // build default user with traits and with extra attributes
  let json = build('user', 'silly', {name: 'Fred'});
  json.get() // => {id: 5, name: 'Fred', style: 'silly'}

  // build user with hats relationship ( hasMany ) composed of a few pre 'built' hats
  let hat1 = build('big-hat');
  let hat2 = build('big-hat');
  let json = build('user', {hats: [hat1, hat2]});
  // note that hats are polymorphic. if they weren't, the hats array would be a list of ids: [1,2]
  json.get() // => {id: 6, name: 'User2', style: 'normal', hats: [{id:1, type:"big_hat"},{id:1, type:"big_hat"}]}

  // build user with company relationship ( belongsTo ) composed of a pre 'built' company
  let company = build('company');
  let json = build('user', {company});
  json.get() // => {id: 7, name: 'User3', style: 'normal', company: 1}

  // build and compose relationships to unlimited degree
  let company1 = build('company', {name: 'A Corp'});
  let company2 = build('company', {name: 'B Corp'});
  let owners = buildList('user', { company:company1 }, { company:company2 });
  let buildJson = build('property', { owners });

  // build user with links to async hasMany properties
  let user = build('user', {properties: {links: '/users/1/properties'}});

  // build user with links to async belongsTo company
  let user = build('user', {company: {links: '/users/1/company'}});

Example of what json payload from build looks like
Although the RESTAdapter is being used, this works the same with ActiveModel or JSONAPI adapters


  let json = build('user', 'with_company', 'with_hats');
  json // =>
    {
      user: {
        id: 1,
        name: 'User1',
        company: 1,
        hats: [
          {type: 'big_hat', id:1},
          {type: 'big_hat', id:2}
        ]
      },
      companies: [
        {id: 1, name: 'Silly corp'}
      ],
      'big-hats': [
        {id: 1, type: "BigHat" },
        {id: 2, type: "BigHat" }
      ]
    }

`FactoryGuy.buildList`

for building json that you can pass as json payload in acceptance tests
takes the same arguments as FactoryGuy.makeList
can compose relationships with other build/buildList payloads
takes serializer for model into consideration
to inspect the json use the get() method
- can use get(index) to get an individual item from the list
use the add method
- to add extra sideloaded data to the payload => .add(payload)
- to add meta data => .add({meta})

Usage:

  import { build, buildList } from 'ember-data-factory-guy';

  let bobs = buildList('bob', 2);  // builds 2 Bob's

  let bobs = buildList('bob', 2, {name: 'Rob'}); // builds 2 Bob's with name of 'Rob'

  // builds 2 users, one with name 'Bob' , the next with name 'Rob'
  let users = buildList('user', { name:'Bob' }, { name:'Rob' });

  // builds 2 users, one with 'boblike' and the next with name 'adminlike' features
  // NOTE: you don't say how many to make, because each trait is making new user
  let users = buildList('user', 'boblike', 'adminlike');

  // builds 2 users:
  // one 'boblike' with stoner style
  // and the next 'adminlike' with square style
  // NOTE: how you are grouping traits and attributes for each one by wrapping them in array
  let users = buildList('user', ['boblike', { style: 'stoner' }], ['adminlike', {style: 'square'}]);

Using `add()` method

when you need to add more json to a payload
- will be sideloaded
  - only JSONAPI, and REST based serializers can do sideloading
  - so DRFSerializer and JSONSerializer users can not use this feature
- you dont need to use json key as in: build('user').add({json: batMan})
- you can just add the payload directly as: build('user').add(batMan)

Usage:

  let batMan = build('bat_man');
  let userPayload = build('user').add(batMan);

  userPayload = {
    user: {
      id: 1,
      name: 'User1',
      style: "normal"
    },
    'super-heros': [
      {
        id: 1,
        name: "BatMan",
        type: "SuperHero"
      }
    ]
  };

when you want to add meta data to payload
- only JSONAPI, and REST based and serializers and DRFSerializer can handle meta data
- so JSONSerializer users can not use this feature ( though this might be a bug on my part )

Usage:

  let json1 = buildList('profile', 2).add({ meta: { previous: '/profiles?page=1', next: '/profiles?page=3' } });
  let json2 = buildList('profile', 2).add({ meta: { previous: '/profiles?page=2', next: '/profiles?page=4' } });

  mockQuery('profile', {page: 2}).returns({ json: json1 });
  mockQuery('profile', {page: 3}).returns({ json: json2 });

 store.query('profile', {page: 2}).then((records)=> // first 2 from json1
 store.query('profile', {page: 3}).then((records)=> // second 2 from json2

Using `get()` method

for inspecting contents of json payload
- get() returns all attributes of top level model
- get(attribute) gives you an attribute from the top level model
- get(index) gives you the info for a hasMany relationship at that index
- get(relationships) gives you just the id or type ( if polymorphic )
  - better to compose the build relationships by hand if you need more info
check out user factory: to see 'boblike' and 'adminlike' user traits

  let json = build('user');
  json.get() //=> {id: 1, name: 'User1', style: 'normal'}
  json.get('id') // => 1

  let json = buildList('user', 2);
  json.get(0) //=> {id: 1, name: 'User1', style: 'normal'}
  json.get(1) //=> {id: 2, name: 'User2', style: 'normal'}

  let json = buildList('user', 'boblike', 'adminlike');
  json.get(0) //=> {id: 1, name: 'Bob', style: 'boblike'}
  json.get(1) //=> {id: 2, name: 'Admin', style: 'super'}

building relationships inline


  let json = build('user', 'with_company', 'with_hats');
  json.get() //=> {id: 1, name: 'User1', style: 'normal'}

  // to get hats (hasMany relationship) info
  json.get('hats') //=> [{id: 1, type: "big_hat"},{id: 1, type: "big_hat"}]

  // to get company ( belongsTo relationship ) info
  json.get('company') //=> {id: 1, type: "company"}

by composing the relationships you can get the full attributes of those associations


  let company = build('company');
  let hats = buildList('big-hats');

  let user = build('user', {company , hats});
  user.get() //=> {id: 1, name: 'User1', style: 'normal'}

  // to get hats info from hats json
  hats.get(0) //=> {id: 1, type: "BigHat", plus .. any other attributes}
  hats.get(1) //=> {id: 2, type: "BigHat", plus .. any other attributes}

  // to get company info
  company.get() //=> {id: 1, type: "Company", name: "Silly corp"}

Using in Other Environments

You can set up scenarios for your app that use all your factories from tests updating config/environment.js.

NOTE: Do not use settings in the test environment. Factories are enabled by default for the test environment and setting the flag tells factory-guy to load the app/scenarios files which are not needed for using factory-guy in testing. This will result in errors being generated if the app/scenarios files do not exist.

  // file: config/environment.js
  // in development you don't have to set enabled to true since that is default
  if (environment === 'development') {
    ENV.factoryGuy = { useScenarios: true };
    ENV.locationType = 'auto';
    ENV.rootURL = '/';
  }

  // or

  if (environment === 'production') {
    ENV.factoryGuy = {enabled: true, useScenarios: true};
    ENV.locationType = 'auto';
    ENV.rootURL = '/';
  }

Place your scenarios in the app/scenarios directory

Start by creating at least a scenarios/main.js file since this is the starting point
Your scenario classes should inherit from Scenario class
A scenario class should declare a run method where you do things like:
- include other scenarios
  - you can compose scenarios like a symphony of notes
- make your data or mock your requests using the typical Factory Guy methods
  - these methods are all built into scenario classes so you don't have to import them

  // file: app/scenarios/main.js
  import {Scenario} from 'ember-data-factory-guy';
  import Users from './users';

  // Just for fun, set the log level ( to 1 ) and see all FactoryGuy response info in console
  Scenario.settings({
    logLevel: 1, // 1 is the max for now, default is 0
  });

  export default class extends Scenario {
    run() {
       this.include([Users]);   // include other scenarios
       this.mockFindAll('products', 3);  // mock some finds
       this.mock({
         type: 'POST',
         url: '/api/v1/users/sign_in',
         responseText: { token:"0123456789-ab" }
       });  // mock a custom endpoint
    }
  }

  // file: app/scenarios/users.js
  import {Scenario} from 'ember-data-factory-guy';

  export default class extends Scenario {
    run() {
      this.mockFindAll('user', 'boblike', 'normal');
      this.mockDelete('user');
    }
  }

Ember Data Model Fragments

As of 2.5.2 you can create factories which contain ember-data-model-fragments. Setting up your fragments is easy and follows the same process as setting up regular factories. The mapping between fragment types and their associations are like so:

Fragment Type | Association --- | --- fragment | FactoryGuy.belongsTo fragmentArray | FactoryGuy.hasMany array | []

For example, say we have the following Employee model which makes use of the fragment, fragmentArray and array fragment types.

// Employee model
export default class Employee extends Model {
  @fragment('name') name
  @fragmentArray('phone-number') phoneNumbers
}

// Name fragment
export default class Name extends Fragment {
  @array('string')  titles
  @attr('string')   firstName
  @attr('string')    lastName
}

// Phone Number fragment
export default class PhoneNumber extends Fragment {
  @attr('string') number
  @attr('string') type
}

A factory for this model and its fragments would look like so:

// Employee factory
FactoryGuy.define('employee', {
  default: {
    name: FactoryGuy.belongsTo('name'), //fragment
    phoneNumbers: FactoryGuy.hasMany('phone-number') //fragmentArray
  }
});

// Name fragment factory
FactoryGuy.define('name', {
  default: {
    titles: ['Mr.', 'Dr.'], //array
    firstName: 'Jon',
    lastName: 'Snow'
  }
});

// Phone number fragment factory
FactoryGuy.define('phone-number', {
  default: {
    number: '123-456-789',
    type: 'home'
  }
});

To set up associations manually ( and not necessarily in a factory ), you should do:

let phoneNumbers = makeList('phone-numbers', 2);
let employee = make('employee', { phoneNumbers });

// OR

let phoneNumbers = buildList('phone-numbers', 2).get();
let employee = build('employee', { phoneNumbers }).get();

For a more detailed example of setting up fragments have a look at:

model test employee test.
acceptance test employee-view-test.

Creating Factories in Addons

If you are making an addon with factories and you want the factories available to Ember apps using your addon, place the factories in test-support/factories instead of tests/factories. They should be available both within your addon and in Ember apps that use your addon.

Ember Django Adapter

available since 2.6.1
everything is setup automatically
sideloading is not supported in DRFSerializer so all relationships should either
- be set as embedded with DS.EmbeddedRecordsMixin if you want to use build/buildList
- or use make/makeList and in your mocks, and return models instead of json:

  let projects = makeList('projects', 2); // put projects in the store
  let user = make('user', { projects });  // attach them to user
  mockFindRecord('user').returns({model: user}); // now the mock will return a user that has projects

using fails() with errors hash is not working reliably
- so you can always just mockWhatever(args).fails()

Custom API formats

FactoryGuy handles JSON-API / RESTSerializer / JSONSerializer out of the box.

In case your API doesn't follow any of these conventions, you can still make a custom fixture builder or modify the FixtureConverters and JSONPayload classes that exist.

before I launch into the details, let me know if you need this hookup and I can guide you to a solution, since the use cases will be rare and varied.

`FactoryGuy.cacheOnlyMode`

Allows you to setup the adapters to prevent them from fetching data with ajax calls
- for single models ( findRecord ) you have to put something in the store
- for collections ( findAll ) you don't have to put anything in the store
Takes except parameter as a list of models you don't want to cache
- These model requests will go to the server with ajax calls and will need to be mocked

This is helpful, when:

you want to set up the test data with make/makeList, and then prevent calls like store.findRecord or store.findAll from fetching more data, since you have already setup the store with make/makeList data.
you have an application that starts up and loads data that is not relevant to the test page you are working on.

Usage:

import FactoryGuy, { makeList } from 'ember-data-factory-guy';
import moduleForAcceptance from '../helpers/module-for-acceptance';

moduleForAcceptance('Acceptance | Profiles View');

test("Using FactoryGuy.cacheOnlyMode", async function() {
  FactoryGuy.cacheOnlyMode();
  // the store.findRecord call for the user will go out unless there is a user
  // in the store
  make('user', {name: 'current'});
  // the application starts up and makes calls to findAll a few things, but
  // those can be ignored because of the cacheOnlyMode

  // for this test I care about just testing profiles
  makeList("profile", 2);

  await visit('/profiles');

  // test stuff
});

test("Using FactoryGuy.cacheOnlyMode with except", async function() {
  FactoryGuy.cacheOnlyMode({except: ['profile']});

  make('user', {name: 'current'});

  // this time I want to allow the ajax call so I can return built json payload
  mockFindAll("profile", 2);

  await visit('/profiles');

  // test stuff
});

Testing models, controllers, components

FactoryGuy needs to setup the factories before the test run.

By default, you only need to call manualSetup(this) in unit/component/acceptance tests

Or you can use the new setupFactoryGuy(hooks) method if your using the new qunit style tests

Sample usage: (works the same in any type of test)

import { setupFactoryGuy } from "ember-data-factory-guy";
    
module('Acceptance | User View', function(hooks) {
  setupApplicationTest(hooks);
  setupFactoryGuy(hooks);

  test("blah blah", async function(assert) {
     await visit('work');
     assert.ok('bah was spoken');
  });
});

Sample model test: profile-test.js
- Use moduleForModel ( ember-qunit ), or describeModel ( ember-mocha ) test helper
- manually set up FactoryGuy

Sample component test: single-user-test.js

Using moduleForComponent ( ember-qunit ), or describeComponent ( ember-mocha ) helper
manually sets up FactoryGuy

import { make, manualSetup }  from 'ember-data-factory-guy';
import hbs from 'htmlbars-inline-precompile';
import { test, moduleForComponent } from 'ember-qunit';

moduleForComponent('single-user', 'Integration | Component | single-user (manual setup)', {
  integration: true,

  beforeEach: function () {
    manualSetup(this);
  }
});

test("shows user information", function () {
  let user = make('user', {name: 'Rob'});

  this.render(hbs`{{single-user user=user}}`);
  this.set('user', user);

  ok(this.$('.name').text().match(user.get('name')));
  ok(this.$('.funny-name').text().match(user.get('funnyName')));
});

Acceptance Tests

For using new style of ember-qunit with setupApplicationTest check out demo here: user-view-test.js:

Using mock methods

Uses pretender
- for mocking the ajax calls made by ember-data
- pretender library is installed with FactoryGuy
http GET mocks
- mockFindRecord
- mockFindAll
- mockReload
- mockQuery
- mockQueryRecord
- takes modifier method returns() for setting the payload response
  - returns() accepts parameters like: json, model, models, id, ids, headers
    - headers are cumulative so you can add as many as you like
    - Example:
```
  let mock = mockFindAll('user').returns({headers: {'X-Man': "Wolverine"});
  mock.returns({headers: {'X-Weapon': "Claws"}});
```
- these mocks are are reusable
  - so you can simulate making the same ajax call ( url ) and return a different payload
http POST/PUT/DELETE
Custom mocks (http GET/POST/PUT/DELETE)
- mock
Use method fails() to simulate failure
Use method succeeds() to simulate success
- Only used if the mock was set to fail with fails() and you want to set the mock to succeed to simulate a successful retry
Use property timesCalled to verify how many times the ajax call was mocked
- works when you are using mockQuery, mockQueryRecord, mockFindAll, mockReload, or mockUpdate
- mockFindRecord will always be at most 1 since it will only make ajax call the first time, and then the store will use cache the second time
- Example:
```
  const mock = mockQueryRecord('company', {}).returns({ json: build('company') });

  FactoryGuy.store.queryRecord('company', {}).then(()=> {
    FactoryGuy.store.queryRecord('company', {}).then(()=> {
      mock.timesCalled //=> 2
    });
  });
```
Use method disable() to temporarily disable the mock. You can re-enable the disabled mock using enable().
Use method destroy() to completely remove the mock handler for the mock. The isDestroyed property is set to true when the mock is destroyed.

setup

As of v2.13.15 mockSetup and mockTeardown are no longer needed
Use FactoryGuy.settings to set:
- logLevel ( 0 - off , 1 - on ) for seeing the FactoryGuy responses
- responseTime ( in millis ) for simulating slower responses
- Example:
```
  FactoryGuy.settings({logLevel: 1, responseTime: 1000});
```

Using fails method

Usable on all mocks
Use optional object arguments status and response and convertErrors to customize
- status : must be number in the range of 3XX, 4XX, or 5XX ( default is 500 )
- response : must be object with errors key ( default is null )
- convertErrors : set to false and object will be left untouched ( default is true )
  - errors must be in particular format for ember-data to accept them
    - FactoryGuy allows you to use a simple style: {errors: {name: "Name too short"}}
    - Behind the scenes converts to another format for ember-data to consume
Examples:

  let errors401 = {errors: {description: "Unauthorized"}};
  let mock = mockFindAll('user').fails({status: 401, response: errors401});

  let errors422 = {errors: {name: "Name too short"}};
  let mock = mockFindRecord('profile').fails({status: 422, response: errors422});

  let errorsMine = {errors: [{detail: "Name too short", title: "I am short"}]};
  let mock = mockFindRecord('profile').fails({status: 422, response: errorsMine, convertErrors: false});

`mockFindRecord`

For dealing with finding one record of a model type => store.findRecord('modelType', id)
Can pass in arguments just like you would for make or build
- mockFindRecord( fixture or model name, optional traits, optional attributes object)
Takes modifier method returns() for controlling the response payload
- returns( model / json / id )
Takes modifier method adapterOptions() for setting adapterOptions ( get passed to urlForFindRecord )
Sample acceptance tests using mockFindRecord: user-view-test.js:

Usage:

   import { build, make, mockFindRecord } from 'ember-data-factory-guy';

To return default factory model type ( 'user' in this case )

   // mockFindRecord automatically returns json for the modelType ( in this case 'user' )
   let mock = mockFindRecord('user');
   let userId = mock.get('id');

Using returns({json}) to return json object

   let user = build('user', 'whacky', {isDude: true});
   let mock = mockFindRecord('user').returns({ json: user });
   // user.get('id') => 1
   // user.get('style') => 'whacky'

   // or to acccomplish the same thing with less code
   let mock = mockFindRecord('user', 'whacky', {isDude: true});
   // mock.get('id') => 1
   // mock.get('style') => 'whacky'
   let user = mock.get();
   // user.id => 1
   // user.style => 'whacky'

Using returns({model}) to return model instance

   let user = make('user', 'whacky', {isDude: false});
   let mock = mockFindRecord('user').returns({ model: user });
   // user.get('id') => 1
   // you can now also user.get('any-computed-property')
   // since you have a real model instance

Simper way to return a model instance

   let user = make('user', 'whacky', {isDude: false});
   let mock = mockFindRecord(user);
   // user.get('id') === mock.get('id')
   // basically a shortcut to the above .returns({ model: user })
   // as this sets up the returns for you

To reuse the mock

   let user2 = build('user', {style: "boring"});
   mock.returns({ json: user2 });
   // mock.get('id') => 2

To mock failure case use fails method

   mockFindRecord('user').fails();

To mock failure when you have a model already

  let profile = make('profile');
  mockFindRecord(profile).fails();
  // mock.get('id') === profile.id

To use adapterOptions

  let mock = mockFindRecord('user').adapterOptions({friendly: true});
  // used when urlForFindRecord (defined in adapter) uses them
  urlForFindRecord(id, modelName, snapshot) {
    if (snapshot && snapshot.adapterOptions) {
       let { adapterOptions }  = snapshot; // => {friendly: true}
       // ... blah blah blah
    }
    // ... blah blah
  }

`mockFindAll`

For dealing with finding all records for a model type => store.findAll(modelType)
Takes same parameters as makeList
- mockFindAll( fixture or model name, optional number, optional traits, optional attributes object)
Takes modifier method returns() for controlling the response payload
- returns( models / json / ids )
Takes modifier method adapterOptions() for setting adapterOptions ( get passed to urlForFindAll )
- used just as in mockFindRecord ( see example there )
Sample acceptance tests using mockFindAll: users-view-test.js

Usage:

   import { buildList, makeList, mockFindAll } from 'ember-data-factory-guy';

To mock and return no results

   let mock = mockFindAll('user');

Using returns({json}) to return json object

   // that has 2 different users:
   let users = buildList('user', 'whacky', 'silly');
   let mock = mockFindAll('user').returns({ json: users });
   let user1 = users.get(0);
   let user2 = users.get(1);
   // user1.style => 'whacky'
   // user2.style => 'silly'

   // or to acccomplish the same thing with less code
   let mock = mockFindAll('user', 'whacky', 'silly');
   let user1 = mock.get(0);
   let user2 = mock.get(1);
   // user1.style => 'whacky'
   // user2.style => 'silly'

Using returns({models}) to return model instances

    let users = makeList('user', 'whacky', 'silly');
    let mock = mockFindAll('user').returns({ models: users });
    let user1 = users[0];
    // you can now also user1.get('any-computed-property')
    // since you have a real model instance

To reuse the mock and return different payload

   let users2 = buildList('user', 3);
   mock.returns({ json: user2 });

To mock failure case use fails() method

   mockFindAll('user').fails();

`mockReload`

To handle reloading a model
- Pass in a record ( or a typeName and id )

Usage:

Passing in a record / model instance

  let profile = make('profile');
  mockReload(profile);

  // will stub a call to reload that profile
  profile.reload()

Using returns({attrs}) to return new attributes

  let profile = make('profile', { description: "whatever" });
  mockReload(profile).returns({ attrs: { description: "moo" } });
  profile.reload(); // description is now "moo"

Using returns({json}) to return all new attributes

  let profile = make('profile', { description: "tomatoes" });
  // all new values EXCEPT the profile id ( you should keep that id the same )
  let profileAllNew = build('profile', { id: profile.get('id'), description: "potatoes" }
  mockReload(profile).returns({ json: profileAllNew });
  profile.reload(); // description = "potatoes"

Mocking a failed reload

  mockReload('profile', 1).fails();

`mockQuery`

For dealing with querying for all records for a model type => store.query(modelType, params)
- Takes modifier method returns() for controlling the response payload
  - returns( models / json / ids )
Takes modifier methods for matching the query params - withParams( object ) - withSomeParams( object )
Sample acceptance tests using mockQuery: user-search-test.js

Usage:

  import FactoryGuy, { make, build, buildList, mockQuery } from 'ember-data-factory-guy';
  let store = FactoryGuy.store;

  // This simulates a query that returns no results
  mockQuery('user', {age: 10});

  store.query('user', {age: 10}}).then((userInstances) => {
    /// userInstances will be empty
  })

with returns( models )

  // Create model instances
  let users = makeList('user', 2, 'with_hats');

  mockQuery('user', {name:'Bob', age: 10}).returns({models: users});

  store.query('user', {name:'Bob', age: 10}}).then((models)=> {
    // models are the same as the users array
  });

with returns ( json )

  // Create json with buildList
  let users = buildList('user', 2, 'with_hats');

  mockQuery('user', {name:'Bob', age: 10}).returns({json: users});

  store.query('user', {name:'Bob', age: 10}}).then((models)=> {
    // these models were created from the users json
  });

with returns( ids )

  // Create list of models
  let users = buildList('user', 2, 'with_hats');
  let user1 = users.get(0);

  mockQuery('user', {name:'Bob', age: 10}).returns({ids: [user1.id]});

  store.query('user', {name:'Bob', age: 10}}).then(function(models) {
    // models will be one model and it will be user1
  });

withParams() / withSomeParams()

  // Create list of models
  let users = buildList('user', 2, 'with_hats');
  let user1 = users.get(0);

  mock = mockQuery('user').returns({ids: [user1.id]});

  mock.withParams({name:'Bob', age: 10})

  // When using 'withParams' modifier, params hash must match exactly
  store.query('user', {name:'Bob', age: 10}}).then(function(models) {
    // models will be one model and it will be user1
  });

  // The following call will not be caught by the mock
  store.query('user', {name:'Bob', age: 10, hair: 'brown'}})

  // 'withSomeParams' is designed to catch requests by partial match
  // It has precedence over strict params matching once applied
  mock.withSomeParams({name:'Bob'})

  // Now both requests will be intercepted
  store.query('user', {name:'Bob', age: 10}})
  store.query('user', {name:'Bob', age: 10, hair: 'brown'}})

`mockQueryRecord`

For dealing with querying for one record for a model type => store.queryRecord(modelType, params)
- takes modifier method returns() for controlling the response payload
  - returns( model / json / id )
takes modifier methods for matching the query params - withParams( object )

Usage:

  import FactoryGuy, { make, build, mockQueryRecord } from 'ember-data-factory-guy';
  let store = FactoryGuy.store;

  // This simulates a query that returns no results
  mockQueryRecord('user', {age: 10});

  store.queryRecord('user', {age: 10}}).then((userInstance) => {
    /// userInstance will be empty
  })

with returns( models )

  // Create model instances
  let user = make('user');

  mockQueryRecord('user', {name:'Bob', age: 10}).returns({model: user});

  store.queryRecord('user', {name:'Bob', age: 10}}).then((model)=> {
    // model is the same as the user you made
  });

with returns( json )

  // Create json with buildList
  let user = build('user');

  mockQueryRecord('user', {name:'Bob', age: 10}).returns({json: user});

  store.queryRecord('user', {name:'Bob', age: 10}}).then((model)=> {
    // user model created from the user json
  });

with returns( ids )

  // Create list of models
  let user = build('user', 'with_hats');

  mockQueryRecord('user', {name:'Bob', age: 10}).returns({id: user.get('id')});

  store.queryRecord('user', {name:'Bob', age: 10}}).then(function(model) {
    // model will be one model and it will be user1
  });

`mockCreate`

Use chainable methods to build the response
- match: takes a hash with attributes or a matching function
  1. attributes that must be in request json
  - These will be added to the response json automatically, so you don't need to include them in the returns hash.
  - If you match on a belongsTo association, you don't have to include that in the returns hash either ( same idea )
  1. a function that can be used to perform an arbitrary match against the request json, returning true if there is a match, false otherwise.
- returns
  - attributes ( including relationships ) to include in response json
Need to import run from @ember/runloop and wrap tests using mockCreate with: run(function() { 'your test' })

Realistically, you will have code in a view action or controller action that will create the record, and setup any associations.


  // most actions that create a record look something like this:
  action: {
    addProject: function (user) {
      let name = this.$('button.project-name').val();
      this.store.createRecord('project', {name: name, user: user}).save();
    }
  }

In this case, you are are creating a 'project' record with a specific name, and belonging to a particular user. To mock this createRecord call here are a few ways to do this using chainable methods.

Usage:

  import { makeNew, mockCreate } from 'ember-data-factory-guy';

  // Simplest case
  // Don't care about a match just handle createRecord for any project
  mockCreate('project');

  // use a model you created already from store.createRecord or makeNew
  // need to use this style if you need the model in the urlForCreateRecord snapshot
  let project = makeNew('project');
  mockCreate(project);

  // Matching some attributes
  mockCreate('project').match({name: "Moo"});

  // Match all attributes
  mockCreate('project').match({name: "Moo", user: user});

  // Match using a function that checks that the request's top level attribute "name" equals 'Moo'
  mockCreate('project').match(requestData => requestData.name === 'Moo');

  // Exactly matching attributes, and returning extra attributes
  mockCreate('project')
    .match({name: "Moo", user: user})
    .returns({created_at: new Date()});

  // Returning belongsTo relationship. Assume outfit belongsTo 'person'
  let person = build('super-hero'); // it's polymorphic
  mockCreate('outfit').returns({attrs: { person }});

  // Returning hasMany relationship. Assume super-hero hasMany 'outfits'
  let outfits = buildList('outfit', 2);
  mockCreate('super-hero').returns({attrs: { outfits }});

mocking a failed create


  // Mocking failure case is easy with chainable methods, just use #fails
  mockCreate('project').match({name: "Moo"}).fails();

  // Can optionally add a status code and/or errors to the response
  mockCreate('project').fails({status: 422, response: {errors: {name: ['Moo bad, Bahh better']}}});

  store.createRecord('project', {name: "Moo"}).save(); //=> fails

`mockUpdate`

mockUpdate(model)
- Single argument ( the model instance that will be updated )
mockUpdate(modelType, id)
- Two arguments: modelType ( like 'profile' ) , and the profile id that will updated
Use chainable methods to help build response:
- match: takes a hash with attributes or a matching function
  1. attributes with values that must be present on the model you are updating
  2. a function that can be used to perform an arbitrary match against the request json, returning true if there is a match, false otherwise.
- returns
  - attributes ( including relationships ) to include in response json
Need to import run from @ember/runloop and wrap tests using mockUpdate with: run(function() { 'your test' })

Usage:

  import { make, mockUpdate } from 'ember-data-factory-guy';

  let profile = make('profile');

  // Pass in the model that will be updated ( if you have it available )
  mockUpdate(profile);

  // If the model is not available, pass in the modelType and the id of
  // the model that will be updated
  mockUpdate('profile', 1);

  profile.set('description', 'good value');
  profile.save() //=> will succeed

  // Returning belongsTo relationship. Assume outfit belongsTo 'person'
  let outfit = make('outfit');
  let person = build('super-hero'); // it's polymorphic
  outfit.set('name','outrageous');
  mockUpdate(outfit).returns({attrs: { person }});
  outfit.save(); //=> saves and returns superhero

  // Returning hasMany relationship. Assume super-hero hasMany 'outfits'
  let superHero = make('super-hero');
  let outfits = buildList('outfit', 2, {name:'bell bottoms'});
  superHero.set('style','laid back');
  mockUpdate(superHero).returns({attrs: { outfits }});
  superHero.save(); // => saves and returns outfits

  // using match() method to specify attribute values
  let profile = make('profile');
  profile.set('name', "woo");
  let mock = mockUpdate(profile).match({name: "moo"});
  profile.save();  // will not be mocked since the mock you set says the name must be "woo"

  // using match() method to specify a matching function
  let profile = make('profile');
  profile.set('name', "woo");
  let mock = mockUpdate(profile).match((requestBody) => {
    // this example uses a JSONAPI Adapter
    return requestBody.data.attributes.name === "moo"
  });
  profile.save();  // will not be mocked since the mock you set requires the request's top level attribute "name" to equal "moo"

  // either set the name to "moo" which will now be mocked correctly
  profile.set('name', "moo");
  profile.save(); // succeeds

  // or

  // keep the profile name as "woo"
  // but change the mock to match the name "woo"
  mock.match({name: "woo"});
  profile.save();  // succeeds

mocking a failed update

  let profile = make('profile');

  // set the succeed flag to 'false'
  mockUpdate('profile', profile.id).fails({status: 422, response: 'Invalid data'});
  // or
  mockUpdate(profile).fails({status: 422, response: 'Invalid data'});

  profile.set('description', 'bad value');
  profile.save() //=> will fail

mocking a failed update and retry with success

  let profile = make('profile');

  let mockUpdate = mockUpdate(profile);

  mockUpdate.fails({status: 422, response: 'Invalid data'});

  profile.set('description', 'bad value');
  profile.save() //=> will fail

  // After setting valid value
  profile.set('description', 'good value');

  // Now expecting success
  mockUpdate.succeeds();

  // Try that update again
  profile.save() //=> will succeed!

`mockDelete`

Need to import run from @ember/runloop and wrap tests using mockDelete with: run(function() { 'your test' })
To handle deleting a model
- Pass in a record ( or a typeName and id )

Usage:

Passing in a record / model instance

  import { make, mockDelete } from 'ember-data-factory-guy';

  let profile = make('profile');
  mockDelete(profile);

  profile.destroyRecord() // => will succeed

Passing in a model typeName and id

  import { make, mockDelete } from 'ember-data-factory-guy';

  let profile = make('profile');
  mockDelete('profile', profile.id);

  profile.destroyRecord() // => will succeed

Passing in a model typeName

  import { make, mockDelete } from 'ember-data-factory-guy';

  let profile1 = make('profile');
  let profile2 = make('p
