Got it working by changing the test key to /\.js$|\.jsx$/, in karma.conf.js. And you have to put the suffix on each .JSX file in each module and in the test:
import Foo from '../src/Foo.jsx';

Hey @lelandrichardson,

It's a bit off topic, but what kind of tool would you recommend for setting up a test coverage reporter on this stack? I've made some attempts using istanbul, karma-coverage, etc and haven't had any success yet. Do you have a favorite tool/method you would recommend?
Any tips or an example would be helpful!

I've tried this code from the main enzyme page:

  it('simulates click events', () => {
    const onButtonClick = sinon.spy();
    const wrapper = shallow(
      <Foo onButtonClick={onButtonClick} />
    );
    wrapper.find('button').simulate('click');
    expect(onButtonClick).to.have.property('callCount', 1);
  });

However, I get the following error:
TypeError: Object is not a constructor (evaluating '_sinon2['default'].spy()')

My set up is exactly the same as this repo. I've also tried using spies from jasmine and other libraries but none of them are working. Has anyone been able to get spies to work in this enzyme/karma setup? Is there's something I'm missing in my config file?
