Using Enzyme with Mocha

Enzyme was originally designed to work with Mocha, so getting it up and running with Mocha should be no problem at all. Simply install it and start using it:

npm i --save-dev enzyme
import React from 'react';
import { expect } from 'chai';
import { mount, shallow } from 'enzyme';

describe('<Foo />', () => {
  it('calls componentDidMount', () => {
    const wrapper = mount(<Foo />);
    expect(Foo.prototype.componentDidMount.calledOnce).to.equal(true);
  });
});
