Using TestUtils in v2.4

See original GitHub issue

How do I use TestUtils with react-rails v2.4? As far as I see TestUtils are no longer bundled in ReactAddons (removed from react-rails), but are available in ReactDOM. React manual states that to use TestUstils one must import/require react-dom/test-utils But how should I do it using react-rails?

@wrzasa My apologies, I mistook this for another open issue without re-reading the comments. I do plan on working on the testing documentation within react-rails. This is currently 4th on my queue.

I downgraded to 2.3.1, then fought with

Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner). in http://localhost:3000/assets/react-server.self-857bafe80cca2229eb9750a4b8396dd4ca9bea6760effc6dfd15c1a66996ca8c.js?body=1 (line 979)

for some time (but only in specs! widget in application worked correctly!), since app/assets/javascripts/server_rendering.js conveniently loaded react second time… finally after a few hours spent to make passing specs pass again on correctly working widget it all works.

So for rails4 and sprockets:

if you have problems with duplicates of React in specs (but not in development), check your app/assets/javascripts/server_rendering.js
I still don’t know how to use v2.4 and Reatc’s TestUtils (maybe it’s not possible – so its worth to mention it i README?).
