* Fixed ReactNativeFiber event system regression introduced in b354db2
Also added test coverage to ReactNativeEvents-test for Fiber
* ReactNative tests now run against fiber renderer when env flag set
Updated the test-framework-setup file so that record-tests runs native tests against ReactNativeFiber. ReactComponentTreeHook native tests all now fail but that's expected.
* Avoid calling setChildren() if no children
A new module has been added (ReactFiberErrorLogger). This logs error information (call stack and component stack) to the console to make errors easier to debug. It also prompts users to use error boundaries if they are not already using them.
In the future, perhaps this will be injectable, enabling users to provide their own handler for custom processing/logging. For the time being, this should help with issues like this / #2461.
* fix failed tests on Windows #8737
* Use regexp literal instead of `RegExp` constructor so that we don't need to bother with escaping special character like `\` and `.`.
Note that by removing the path separator in regexp, I've relaxed the matching condition a little.Since there's little chance we have files like `XXXReact.d.ts`,it should not matter.
* Add a failing test for recursion check
* Make requestIdleCallback() and requestAnimationFrame() shims async
They no longer need to be sync in tests because we already made DOM renderer sync by default.
This fixes a crash when testing incrementalness in DOM renderer itself.
* Style fix
* Fix lint
I'll plan to change all of our console.error and component-tree expects to expectDev. It's a little annoying that we need to make sure tests don't throw (see my change to normalizeCodeLocInfo) but any alternative would seem to require two separate test runs or a much more cumbersome syntax.
Jest 15 has just been released and is way more awesome: http://facebook.github.io/jest/blog/2016/09/01/jest-15.html
This pull request updates jest from version 12 to 15. Right now there's a fix in jest around Symbol that hasn't been released yet, so this will break CI and cannot be merged it. But once it ships by the end of the day, we'll be good to go :)
See comments inline for all the changes I've done.
We currently write all our tests against the DOM implementation.
I need a way to run the Fiber tests against it. But I don't want
to take on any package dependencies on Fiber modules yet.
There's a problem with jest right now where you can't globally
mock modules that already exist. So I have to add a global call
to jest.mock.
Luckily we already have a way to test the useCreateElement paths
using a feature flag. I won't activate this flag in travis until
it passes, but the idea is to run all three variants in travis.
I'm not sure that invoking rAF and rIC synchronously is the best
way to test this since it doesn't capture the backwards
compatibility aspect. I.e. the fact that people might be relying
on the synchronous nature in real apps too. It's a start.
Ideally, jest would have these built-in.
Test Plan: Changed the preprocessor to log the output of babel.transform and saw
```
var _jsxFileName = 'src/isomorphic/modern/element/__tests__/ReactJSXElementValidator-test.js';
```
in the resulting output, instead of an absolute path.
You could make the argument that this should be optional, but it doesn't
work without it so we might as well just enforce it.
Makes `jest` work by default.
Turns out jest is _incredibly_ slow at resolving require paths like `require('fbjs/lib/foo')`. Like several milliseconds per require. Really adds up when all our files require `invariant` and `warning`. Here's a temporary hack to make things fast again.
Test Plan:
```
npm test src/renderers/shared/reconciler/__tests__/ReactCompositeComponent-test.js
```
has a self-proclaimed runtime of ~8 seconds now instead of ~35 seconds.
This reworks a few things in building and distributing React. The biggest change is using fbjs to share dependencies with other libraries. We're also using Gulp for some build steps.
