Sunil Pai e1c5e8720d warn if passive effects get queued outside of an act() call. (#15763)
* warn if passive effects get queued outside of an act() call

While the code itself isn't much (it adds the warning to mountEffect() and updateEffect() in ReactFiberHooks), it does change a lot of our tests. We follow a bad-ish pattern here, which is doing asserts inside act() scopes, but it makes sense for *us* because we're testing intermediate states, and we're manually flush/yield what we need in these tests.

This commit has one last failing test. Working on it.

* pass lint

* pass failing test, fixes another

- a test was failing in ReactDOMServerIntegrationHooks while testing an effect; the behaviour of yields was different from browser and server when wrapped with act(). further, because of how we initialized modules, act() around renders wasn't working corrrectly. solved by passing in ReactTestUtils in initModules, and checking on the finally yielded values in the specific test.
- in ReactUpdates, while testing an infinite recursion detection, the test needed to be wrapped in an act(), which would have caused the recusrsion error to throw. solived by rethrowing the error from inside the act().

* pass ReactDOMServerSuspense

* stray todo

* a better message, consistent with the state update one.

react-debug-tools

This is an experimental package for debugging React renderers.

Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.

Use it at your own risk.
