Philipp Spieß 036ae3c6e2 Use native event dispatching instead of Simulate or SimulateNative (#13023)
* Use native event dispatching instead of Simulate or SimulateNative

In #12629 @gaearon suggested that it would be better to drop usage of
`ReactTestUtils.Simulate` and `ReactTestUtils.SimulateNative`. In this
PR I’m attempting at removing it from a lot of places with only a few
leftovers.

Those leftovers can be categorized into three groups:

1. Anything that tests that `SimulateNative` throws. This is a property
   that native event dispatching doesn’t have so I can’t convert that
   easily. Affected test suites: `EventPluginHub-test`,
   `ReactBrowserEventEmitter-test`.
2. Anything that tests `ReactTestUtils` directly. Affected test suites:
   `ReactBrowserEventEmitter-test` (this file has one test that reads
    "should have mouse enter simulated by test utils"),
    `ReactTestUtils-test`.
3. Anything that dispatches a `change` event. The reason here goes a bit
   deeper and is rooted in the way we shim onChange. Usually when using
   native event dispatching, you would set the node’s `.value` and then
   dispatch the event. However inside [`inputValueTracking.js`][] we
   install a setter on the node’s `.value` that will ignore the next
   `change` event (I found [this][near-perfect-oninput-shim] article
   from Sophie that explains that this is to avoid onChange when
   updating the value via JavaScript).

All remaining usages of `Simulate` or `SimulateNative` can be avoided
by mounting the containers inside the `document` and dispatching native
events.

Here some remarks:

1. I’m using `Element#click()` instead of `dispatchEvent`. In the jsdom
   changelog I read that `click()` now properly sets the correct values
   (you can also verify it does the same thing by looking at the
   [source][jsdom-source]).
2. I had to update jsdom in order to get `TouchEvent` constructors
   working (and while doing so also updated jest). There was one
   unexpected surprise: `ReactScheduler-test` was relying on not having
   `window.performance` available. I’ve recreated the previous
   environment by deleting this property from the global object.
3. I was a bit confused that `ReactTestUtils.renderIntoDocument()` does
   not render into the document 🤷‍

Brian Vaughn 97e2911508 RFC 6: Deprecate unsafe lifecycles (#12028)
* Added unsafe_* lifecycles and deprecation warnings
If the old lifecycle hooks (componentWillMount, componentWillUpdate, componentWillReceiveProps) are detected, these methods will be called and a deprecation warning will be logged. (In other words, we do not check for both the presence of the old and new lifecycles.) This commit is expected to fail tests.

* Ran lifecycle hook codemod over project
This should handle the bulk of the updates. I will manually update TypeScript and CoffeeScript tests with another commit.
The actual command run with this commit was: jscodeshift --parser=flow -t ../react-codemod/transforms/rename-unsafe-lifecycles.js ./packages/**/src/**/*.js

* Manually migrated CoffeeScript and TypeScript tests

* Added inline note to createReactClassIntegration-test
Explaining why lifecycles hooks have not been renamed in this test.

* Udated NativeMethodsMixin with new lifecycle hooks

* Added static getDerivedStateFromProps to ReactPartialRenderer
Also added a new set of tests focused on server side lifecycle hooks.

* Added getDerivedStateFromProps to shallow renderer
Also added warnings for several cases involving getDerivedStateFromProps() as well as the deprecated lifecycles.
Also added tests for the above.

* Dedupe and DEV-only deprecation warning in server renderer

* Renamed unsafe_* prefix to UNSAFE_* to be more noticeable

* Added getDerivedStateFromProps to ReactFiberClassComponent
Also updated class component and lifecyle tests to cover the added functionality.

* Warn about UNSAFE_componentWillRecieveProps misspelling

* Added tests to createReactClassIntegration for new lifecycles

* Added warning for stateless functional components with gDSFP

* Added createReactClass test for static gDSFP

* Moved lifecycle deprecation warnings behind (disabled) feature flag

Updated tests accordingly, by temporarily splitting tests that were specific to this feature-flag into their own, internal tests. This was the only way I knew of to interact with the feature flag without breaking our build/dist tests.

* Tidying up

* Tweaked warning message wording slightly
Replaced 'You may may have returned undefined.' with 'You may have returned undefined.'

* Replaced truthy partialState checks with != null

* Call getDerivedStateFromProps via .call(null) to prevent type access

* Move shallow-renderer didWarn* maps off the instance

* Only call getDerivedStateFromProps if props instance has changed

* Avoid creating new state object if not necessary

* Inject state as a param to callGetDerivedStateFromProps
This value will be either workInProgress.memoizedState (for updates) or instance.state (for initialization).

* Explicitly warn about uninitialized state before calling getDerivedStateFromProps.
And added some new tests for this change.

Also:
* Improved a couple of falsy null/undefined checks to more explicitly check for null or undefined.
* Made some small tweaks to ReactFiberClassComponent WRT when and how it reads instance.state and sets to null.

* Improved wording for deprecation lifecycle warnings

* Fix state-regression for module-pattern components
Also add support for new static getDerivedStateFromProps method

* Add warning in server renderer if class doesn't extend React.Component

In dev mode, while server rendering, a warning will be thrown if there is a class that doesn't extend React.Component.

* Use `.toWarnDev` matcher and deduplicate warnings

Brian Vaughn a442d9bc08 Update additional tests to use .toWarnDev() matcher (#11952)
* Migrated several additional tests to use new .toWarnDev() matcher

* Migrated ReactDOMComponent-test to use .toWarnDev() matcher

Note this test previous had some hacky logic to verify errors were reported against unique line numbers. Since the new matcher doesn't suppor this, I replaced this check with an equivalent (I think) comparison of unique DOM elements (eg div -> span)

* Updated several additional tests to use the new .toWarnDev() matcher

* Updated many more tests to use .toWarnDev()

Dan Abramov 6041f481b7 Run Jest in production mode (#11616)
* Move Jest setup files to /dev/ subdirectory

* Clone Jest /dev/ files into /prod/

* Move shared code into scripts/jest

* Move Jest config into the scripts folder

* Fix the equivalence test

It fails because the config is now passed to Jest explicitly.
But the test doesn't know about the config.

To fix this, we just run it via `yarn test` (which includes the config).
We already depend on Yarn for development anyway.

* Add yarn test-prod to run Jest with production environment

* Actually flip the production tests to run in prod environment

This produces a bunch of errors:

Test Suites: 64 failed, 58 passed, 122 total
Tests:       740 failed, 26 skipped, 1809 passed, 2575 total
Snapshots:   16 failed, 4 passed, 20 total

* Ignore expectDev() calls in production

Down from 740 to 175 failed.

Test Suites: 44 failed, 78 passed, 122 total
Tests:       175 failed, 26 skipped, 2374 passed, 2575 total
Snapshots:   16 failed, 4 passed, 20 total

* Decode errors so tests can assert on their messages

Down from 175 to 129.

Test Suites: 33 failed, 89 passed, 122 total
Tests:       129 failed, 1029 skipped, 1417 passed, 2575 total
Snapshots:   16 failed, 4 passed, 20 total

* Remove ReactDOMProduction-test

There is no need for it now. The only test that was special is moved into ReactDOM-test.

* Remove production switches from ReactErrorUtils

The tests now run in production in a separate pass.

* Add and use spyOnDev() for warnings

This ensures that by default we expect no warnings in production bundles.
If the warning *is* expected, use the regular spyOn() method.

This currently breaks all expectDev() assertions without __DEV__ blocks so we go back to:

Test Suites: 56 failed, 65 passed, 121 total
Tests:       379 failed, 1029 skipped, 1148 passed, 2556 total
Snapshots:   16 failed, 4 passed, 20 total

* Replace expectDev() with expect() in __DEV__ blocks

We started using spyOnDev() for console warnings to ensure we don't *expect* them to occur in production. As a consequence, expectDev() assertions on console.error.calls fail because console.error.calls doesn't exist. This is actually good because it would help catch accidental warnings in production.

To solve this, we are getting rid of expectDev() altogether, and instead introduce explicit expectation branches. We'd need them anyway for testing intentional behavior differences.

This commit replaces all expectDev() calls with expect() calls in __DEV__ blocks. It also removes a few unnecessary expect() checks that no warnings were produced (by also removing the corresponding spyOnDev() calls).

Some DEV-only assertions used plain expect(). Those were also moved into __DEV__ blocks.

ReactFiberErrorLogger was special because it console.error()'s in production too. So in that case I intentionally used spyOn() instead of spyOnDev(), and added extra assertions.

This gets us down to:

Test Suites: 21 failed, 100 passed, 121 total
Tests:       72 failed, 26 skipped, 2458 passed, 2556 total
Snapshots:   16 failed, 4 passed, 20 total

* Enable User Timing API for production testing

We could've disabled it, but seems like a good idea to test since we use it at FB.

* Test for explicit Object.freeze() differences between PROD and DEV

This is one of the few places where DEV and PROD behavior differs for performance reasons.
Now we explicitly test both branches.

* Run Jest via "yarn test" on CI

* Remove unused variable

* Assert different error messages

* Fix error handling tests

This logic is really complicated because of the global ReactFiberErrorLogger mock.
I understand it now, so I added TODOs for later.

It can be much simpler if we change the rest of the tests that assert uncaught errors to also assert they are logged as warnings.
Which mirrors what happens in practice anyway.

* Fix more assertions

* Change tests to document the DEV/PROD difference for state invariant

It is very likely unintentional but I don't want to change behavior in this PR.
Filed a follow up as https://github.com/facebook/react/issues/11618.

* Remove unnecessary split between DEV/PROD ref tests

* Fix more test message assertions

Anushree Subramani 3f1f3dc12e Deduplicated many warnings (#11140) (#11216)
*  Deduplicated many warnings (#11140)

*  Deduplicated the following warnings:

1.  Can only update a mounted or mounting component.
    This usually means you called setState, replaceState,
    or forceUpdate on an unmounted component. This is a no-op

2.  %s.componentWillReceiveProps(): Assigning directly to
    this.state is deprecated (except inside a component's
    constructor). Use setState instead.'

3.  An update (setState, replaceState, or forceUpdate) was scheduled
    from inside an update function. Update functions should be pure,
    with zero side-effects. Consider using componentDidUpdate or a
    callback.

4.  setState(...): Cannot call setState() inside getChildContext()

* Code review changes made for #11140

* Minor style fix

* Test deduplication for noop updates in server renderer

* Test deduplication for cWRP warning

* Test deduplication for cWM setState warning

* Test deduplication for unnmounted setState warning

Dan Abramov d9c1dbd617 Use Yarn Workspaces (#11252)
* Enable Yarn workspaces for packages/*

* Move src/isomorphic/* into packages/react/src/*

* Create index.js stubs for all packages in packages/*

This makes the test pass again, but breaks the build because npm/ folders aren't used yet.
I'm not sure if we'll keep this structure--I'll just keep working and fix the build after it settles down.

* Put FB entry point for react-dom into packages/*

* Move src/renderers/testing/* into packages/react-test-renderer/src/*

Note that this is currently broken because Jest ignores node_modules,
and so Yarn linking makes Jest skip React source when transforming.

* Remove src/node_modules

It is now unnecessary. Some tests fail though.

* Add a hacky workaround for Jest/Workspaces issue

Jest sees node_modules and thinks it's third party code.

This is a hacky way to teach Jest to still transform anything in node_modules/react*
if it resolves outside of node_modules (such as to our packages/*) folder.

I'm not very happy with this and we should revisit.

* Add a fake react-native package

* Move src/renderers/art/* into packages/react-art/src/*

* Move src/renderers/noop/* into packages/react-noop-renderer/src/*

* Move src/renderers/dom/* into packages/react-dom/src/*

* Move src/renderers/shared/fiber/* into packages/react-reconciler/src/*

* Move DOM/reconciler tests I previously forgot to move

* Move src/renderers/native-*/* into packages/react-native-*/src/*

* Move shared code into packages/shared

It's not super clear how to organize this properly yet.

* Add back files that somehow got lost

* Fix the build

* Prettier

* Add missing license headers

* Fix an issue that caused mocks to get included into build

* Update other references to src/

* Re-run Prettier

* Fix lint

* Fix weird Flow violation

I didn't change this file but Flow started complaining.
Caleb said this annotation was unnecessarily using $Abstract though so I removed it.

* Update sizes

* Fix stats script

* Fix packaging fixtures

Use file: instead of NODE_PATH since NODE_PATH.
NODE_PATH trick only worked because we had no react/react-dom in root node_modules, but now we do.

file: dependency only works as I expect in Yarn, so I moved the packaging fixtures to use Yarn and committed lockfiles.
Verified that the page shows up.

* Fix art fixture

* Fix reconciler fixture

* Fix SSR fixture

* Rename native packages
