mock-server-api

A project to facilitate the use of Mountebank

The key points for this project are:

1. Mountebank - server used to run the mocked API

Configurations

To use this project the easiest way is to use the /sample-project as it already contains a package.json configured and the structure to initiate the mocked api.

src/mconfig.ts

• configuration file with required values

src/stubs

• folder with all stubs packages that will be used
• every folder directly inside /stubs must have an index.ts file that exports the stubs object
• the export stubs object is as follow:

it is an object that map each property or 'stubName' to it's stub object, the stub has two properties: predicates and responses.

As you can see the predicates in https://www.mbtest.org/docs/api/predicates or http://localhost:2525/docs/api/predicates if the mountebank is running.

And the responses in https://www.mbtest.org/docs/api/stubs or http://localhost:2525/docs/api/stubs

src/stubs/index.ts

• file that load and configure all stubs packages

src/index.ts

• file responsible to communicate with the Mountebank and configure the mock server

Required configurations

• On the command line inside the base folder of the repository, run: npm i to install everything

Run steps using

• On the command line run: npm run mb

• On an new command line run: npm run mock

  • Every time that its necessary to update the mock server it is just this last command again.

Integrating with another project:

• An project can copy all the sample project inside of it and make it available to others as unique project, with only a few configuration options.

• Structure example:

The current mock-server project

• Inside /mocks/stubs there are some folders that can be discarded, they are there to be used as a sample;

There is two methods of generating the mock:

1. from any index.ts inside a folder in /mock/stubs export the stubs as: export const stubs
   1. This stubs const is a mapper of stubs as { anyStubName: {} as StubData } as StubCollection
   2. For better understanding see the file @types/index.ts there is a lot of definitions including StubData and StubCollection
2. from any index.ts inside a folder in /mock/stubs export the apis as: export const apis
   1. A better example is implemented on the folder /mocks/stubs/projects there is use of urlParams, generated fields and query functions;

Query filters options (using list-total model api)

There are some options for query filters they are:

• "CONTAINS" : the query param name must be equal to the param inside the object, the query param value must be inside the object param value

• any other string: the same as "CONTAINS" but it will search for equality;

• array [param, type]: the 'param' is the param name in the object, the 'type' follow the above rules

• (funtion) : the funcion will have this structure: (list: any[], value: any, config: ConfigInjection) => any[];

  • list: array of values that would be returned without this filter,
  • value: the value of the query param;
  • config: object containing all the values passed by Mountebank

• queryPriority: set the priority of an query, if the priority is greater than 9 that query will be executed after extract the list length, default value is 5.

• list-total/utils.ts there are 2 functions that could be used to add query function: sort = used to sort the result list, offset = used for pagination, a sample of use is on /mocks/stubs/projects

THE NEWEST SUPER COOL WAY TO CREATE RESPONSES:

On the sample-project there is this folder withImport with this StubCollection:

The main point is to use an exported function inside the stub response, it will only need to pass the path to the function on the following format: "/pathToFolder/InsideStubs/Location/FileName.functionExported"
