Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Assertions for redux actions testing.

This library adds assertions for redux actions testing.
It use redux-mock-store to mock redux store.

Supported Assertion Frameworks/Libraries:

If you have not found assertion framework/library that you are using - please add comment into this issue.

What it does:

Allows to avoid retesting nested action creators

It allows to test only actions that need to be tested.

Example:
We have two actions (A, B). Each one makes async http requests.
Action A makes a request and if the result is successful it triggers Action B.
Action B is also used as an independent action.
Action B can be tested separately.
Therefore, we don't need to test it again in Action A.

Actions:

function actionA() {
  return dispatch => {
    dispatch(actionAStart());
    return api.getA().then(response => {
        dispatch(actionAFinish(response));
        dispatch(actionB());
      }).catch(err => {
        dispatch(actionAFailure(err));
      });
    };
}

function actionB() {
  return dispatch => {
    dispatch(actionBStart());
    return api.getB().then(response => {
        dispatch(actionBFinish(response));
      }).catch(err => {
        dispatch(actionBFailure(err));
      });
    };
}

Without:

const expectedActions = [
  { type: action_a_start },
  { type: action_a_success },   
  { type: action_b_start }, // retesting of action B
  { type: action_b_success } // retesting of action B];
const store = mockStore({ todos: [] });
store.dispatch(actionA()).then(() => {
  expect(store.getActions()).toEqual(expectedActions);
}).then(done).catch(done);

With:

expect(actionA()).withState({ todos: [] }).toDispatch([
  { type: action_a_start },
  { type: action_a_success },
  actionB() // just executing tested action
], done);

Reduces repetitive code of test methods

It reduces boilerplate of test methods and makes testing fluent.

Without:

const store = mockStore(/* initial state */);
const expectedActions = [
  { type: types.FETCH_TODOS_REQUEST },
  /* All expected triggered action objects */
];
store.dispatch(fetchData()).then(() => {
  const actions = store.getActions();
  expect(actions).toEqual(expectedActions);
}).then(done).catch(done);

With:

const expectedActions = [
  /*All expected triggered action objects or action creator functions*/
];
expect(fetchData()).toDispatchActions(expectedActions, done);

With using customised store state:

expect(fetchData()).withState({/*custom state*/}).toDispatchActions(expectedActions, done);

Simplifies initial setup

It provides singe-time global configuration for middlewares and initial store state.

Without:

const middlewares = [thunk];
const mockStore = configureStore(middlewares);
const store = mockStore({ /*initial store object*});

With:

registerMiddlewares([ thunk ]);
// to set custom initial state 
registerInitialStoreState(/*object of function*/);
// to generate initial state of your application
registerInitialStoreState(buildInitialStoreState(/*your root reducer*/));

Installation

Using npm:

$ npm install --save-dev redux-actions-assertions

Redux middlewares registration

// using ES6 modules
import { registerMiddlewares } from 'redux-actions-assertions';

// using CommonJS modules
var registerMiddlewares = require('redux-actions-assertions').registerMiddlewares;

// registration
registerMiddlewares([
  /* Here you need to list your middlewares */
]);

Default initial store state registration

By using state object or function:

// using ES6 modules
import { registerInitialStoreState } from 'redux-actions-assertions';

// using CommonJS modules
var registerInitialStoreState = require('redux-actions-assertions').registerInitialStoreState;

// registration
registerInitialStoreState(/* default initial state object or function */);

By using your root reducer:

// using ES6 modules
import { buildInitialStoreState, registerInitialStoreState } from 'redux-actions-assertions';

// using CommonJS modules
var reduxActionsAssertions = require('redux-actions-assertions');
var registerInitialStoreState = reduxActionsAssertions.registerInitialStoreState;

// registration
registerInitialStoreState(buildInitialStoreState(/* root reducer function */));
