Use enzyme in tests

[gaearon]

We should start using enzyme in component tests. It is great and the community seems to have converged on it. We should migrate all our existing tests from ReactTestUtils to enzyme, and use it for any new component tests.

I don’t plan to work on this, but if you’d like, please leave a comment stating your intention, and then send a PR when you have something to show so we keep a conversation. If you feel you don’t have the time, don’t worry—just let us know so another person can pick up the task.

Help wanted 😉

I'll take it.

I've been working on updating the todomvc example. That example had some existing integration tests. I haven't had the opportunity to try enzyme yet. I can work on converting those existing tests over to enzyme.

Thanks, please do! It seems that counter example is the best candidate right now. We plan to completely replace todomvc so it might not be worth trying there (and @mjw56 plans to take care of it anyway). Please send a PR after you’ve done with counter and we can figure out next steps.

Thank you for the counter update! If you’d like, feel free to add enzyme tests to either of these examples:

• https://github.com/reactjs/redux/tree/master/examples/shopping-cart
• https://github.com/reactjs/redux/tree/master/examples/tree-view
• https://github.com/reactjs/redux/tree/master/examples/real-world

They currently have no component tests at all.

[fshowalter]

Will do.

Hey I am interested in adding enzyme tests too to the projects with none. May be I'll start with the real world one?

[gaearon]

@fshowalter @borisyankov Please work it out between yourselves 😉

[fshowalter]

@borisyankov real world is all yours 😉

@gaearon did you want to keep the tests under /test or colocate them with the source in a tests folder ala React?
