* Removed the enableGetDerivedStateFromCatch feature flag (aka permanently enabled the feature)
* Forked/copied ReactErrorBoundaries to ReactLegacyErrorBoundaries for testing componentDidCatch
* Updated error boundaries tests to apply to getDerivedStateFromCatch
* Renamed getDerivedStateFromCatch -> getDerivedStateFromError
* Warn if boundary with only componentDidCatch swallows error
* Fixed a subtle reconciliation bug with render phase error boundary
A recent change to the scheduler caused a regression when scheduling
many updates within a single batch. Added a test case that would
have caught this.
* 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
* 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()
* Updated several additional tests to use .toWarnDev() matcher
* Updated ReactElementValidator to distinguish between Array and Object in its warning. Also updated its test to use .toWarnDev() matcher.
* Updated a couple of additional tests
* Removed unused normalizeCodeLocInfo() methods
* 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
* Make validateDOMNesting tests DEV-only
* Fix error message assertions
* Document existing DEV/PROD message difference (possible bug)
* Change mocking assertions to be DEV-only
* Fix the error code test
* Fix more error message assertions
* Fix the last failing test due to known issue
* Run production tests on CI
* Unify configuration
* Fix coverage script
* Remove expectDev from eslintrc
* Run everything in band
We used to before, too. I just forgot to add the arguments after deleting the script.
* 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
