Wrap your root component with the Provider component

import { Provider } from 'react-redux';

<Provider store={store} key="provider">

The store is created with

import { createStore } from 'redux';

const store = createStore(reducers);

Reducers is the combined reducers of your application

import { combineReducers } from 'redux';
import { routerReducer as routing } from 'react-router-redux';

export default combineReducers({

A reducer boils down to a function that takes a state and an action and return a new state

const homeReducer = (state = initialState, action) => {
  return {
    something: action.something,

Your root components now have to be exported with a decorator (or a function call), example with decorator:

const mapStateToProps = (state) => {
  return {

const mapDispatchToProps = (dispatch: Dispatch<any>) => ({
  toggleLoading: (options) => dispatch({ type: homeTypes.loading, ...options }),

@(connect(mapStateToProps, mapDispatchToProps) as any)


You can call mockStore with a function like mockStore(() => mockState); and then modify mockState at any point to simulate different states of the application.

Be careful when testing a reducer with an undefined value, see 13c63de
