Example Integration Test. This test is not a unit test because it's testing multiple levels in the App tree.

chai.use(chaiEnzyme());
var expect = require('chai').expect
require('../../jsdom');

example isolated React "dumb" component unit test

I'm in the middle of some refactoring (ripping out a few things locally at the moment) but here's a view of isolated unit tests being run. Since these tests are truly isolated (not coupled to implementation details, only the right tests break for a given bug...that's important, because brittle tests can cause much pain).
example integration test making a real API call to my new backend Node REST API:
import React from 'react';
import chai from 'chai';
import chaiEnzyme from 'chai-enzyme';
chai.use(chaiEnzyme());
require('../../jsdom');
import { mount } from 'enzyme';
const expect = require('chai').expect;
import { createStore, applyMiddleware } from 'redux'
import thunk from 'redux-thunk'
import { Provider } from 'react-redux';
import rootReducer from '../../../client/reducers/root';
import FeaturedCompaniesContainer from '../../../client/company/containers/FeaturedCompaniesContainer';
describe('Feature - FeaturedCompanies - Integration', () => {
let Container;
before(() => {
Container = <Provider store={createStore(rootReducer, applyMiddleware(thunk))}>
<FeaturedCompaniesContainer />
</Provider>
});
it('returns featured companies', async () => {
const container = await new Promise(resolve => resolve(mount(Container))),
groups = container.find('.ft-featured-company-groups');
expect(groups.length).to.be.greaterThan(1);
});
})
React-redux example Connected Container
/*flow*/
import React, { Component } from 'react';
import { connect } from 'react-redux';
import FeaturedCompanies from '../FeaturedCompanies';
import { fetchNewCompanies } from '../../actions/companies';
class FeaturedCompaniesContainer extends Component {
componentDidMount(){
if(!this.props.companies){
fetchNewCompanies();
}
}
render(){
return(<FeaturedCompanies />)
}
}
export const mapStateToProps = (state) => ({
companies: state.featuredCompanies
});
export default connect(mapStateToProps)(FeaturedCompaniesContainer);
