Redux TDD

Install

npm install --save-dev redux-tdd

import reduxTdd from 'redux-tdd';

// reduxTdd() takes as arguments an object which will be passed to redux combineReducers()
// and a function which returns an array of components that map your state to props
reduxTdd({ counter: counterReducer }, state => [
  <Counter
    onClick={incrementAction}
    counter={state.counter.count} />
])
.action(props => props.onClick()) // action() takes a function that must return a redux action
.toMatchProps({ counter: 1 }) // toMatchProps() checks whether the component took the correct props
.contains(<span>1</span>) // finally contains() checks that the component contains correct value
