A mock store for 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.

How to use

// 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 initialState = {}
  const addTodo = { type: 'ADD_TODO' }

  const store = mockStore(initialState)
  store.dispatch(addTodo)

  const actions = store.getActions()

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

// Promise test example with mocha and expect
it('should execute promise', () => {
    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({})

    // Return the promise
    return store.dispatch(fetchData())
      .then(() => {
        expect(store.getActions()[0]).toEqual(success())
      })
})
