# redux-mock-store

A mock store for your testing your redux async action creators and middleware. The mock store will store the dispatched actions in an array to be used in your tests.

## Install

```
npm install redux-mock-store --save-dev
```

## How to use

```js

// actions.test.js

import configureStore from 'redux-mock-store';
import thunk from 'redux-thunk';

const middlewares = [thunk]; // add your middlewares like `redux-thunk`
const mockStore = configureStore(middlewares);

// Test example with mocha and expect
it('should dispatch action', () => {
  const getState = {}; // initial state of the store
  const addTodo = { type: 'ADD_TODO' };

  const store = mockStore(getState);
  store.dispatch(addTodo);

  const actions = store.getActions();

  expect(actions).toEqual([addTodo]);
});

// Promise test example with mocha and expect
it('should execute promise', (done) => {
    function success() {
      return {
        type: 'FETCH_DATA_SUCCESS'
      };
    }

    function fetchData() {
      return dispatch => {
        return fetch('/users.json') // Some async action with promise
          .then(() => dispatch(success()));
      };
    }

    const store = mockStore({});

    store.dispatch(fetchData())
      .then(() => {
        expect(store.getActions()[0]).toEqual(success())
        done();
      });
})
```
