Mock react-redux for testing

redux-react-mock

Mock the react-redux package.

Installation

yarn add --dev react-redux-mock

npm install --save-dev react-redux-mock

Usage

Let's assume that you have an connected component with this structure.

import React from 'react';
import { connect } from 'react-react';

const Text = ({ content }) => <p>{content}</p>;
const contentSelector = state => state.content;

const ConnectedText = compose(
  connect(state => {
    content: contentSelector(state),
  }),
)(Text);

export default ConnectedText;

This is how you can test the component above with react-redux-mock?

jest.mock('react-redux', () => require('react-redux-mock'));
import { __setState } from 'react-redux';
import { mount } from 'enzyme';

describe('Text component', () => {
  it('renders correctly', () => {
    __setState({
      content: 'foo',
    });
    const component = mount(<ConnectedText />);
    expect(component).toMatchSnapshot();
  });
});

Notice that you can render the connected component itself without defining what is the store and the Provider component.
