While writing tests for unsafe async warnings, I noticed that in certain cases, errors were swallowed by the toWarnDev matcher and resulted in confusing test failures. For example, if an error prevented the code being tested from logging an expected warning- the test would fail saying that the warning hadn't been logged rather than reporting the unexpected error. I think a better approach for this is to always treat caught errors as the highest-priority reason for failing a test.
I reran all of the test cases for this matcher that I originally ran with PR #11786 and ensured they all still pass.
* 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
* Adds danger_js with an initial rule for warning about large PRs

* [WIP] Get the before and after for the build results
* [Dev] More work on the Dangerfile
* [Danger] Split the reports into sections based on their package
* Remove the --extract-errors on the circle build
* [Danger] Improve the lookup for previous -> current build to also include the environment
* Fix rebase
The TestUtils lost media events when they were pulled out of the
topLevelTypes constant. This commit adds them back by concatenating
the media event keys to the list of top level types.
We want to start refactoring some of the event constants, but we don't
have a great way to confirm media events work as intended. This commit
adds a new DOM test fixture to verify that media events bubble.
In absence of a value, radio and checkboxes report a value of
"on". Between 16 and 16.2, we assigned a node's value to it's current
value in order to "dettach" it from defaultValue. This had the
unfortunate side-effect of assigning value="on" to radio and
checkboxes

* Added 'flow-coverage-report' package for discussion
* Aded flow-coverage command and configuration file
* Moved FLow coverage config file to scripts/flow/coverage-config
* Moved Flow coverage config back to root as dotfile
* Runs a lint rule on tests only that errors if it sees `fdescribe` or `fit` calls.
* Changes `file:` to `link:` for our custom, internal rules (just to simplify updating these in the future).
* Updates `eslint` from 3.10 -> 4.1 and `babel-eslint` from 7.1 -> 8.0 so that we can run this new rule only against tests.
* 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
* Deduplicate client-side warning if class doesn't extend React.Component
* Default componentName to Unknown if null
Removes the `useSyncScheduling` option from the HostConfig, since it's
no longer needed. Instead of globally flipping between sync and async,
our strategy will be to opt-in specific trees and subtrees.
* Updated misleading error message in production environment when adding ref to a functional component
* Reverted changes to codes.json
* Updated error message
* Warn about spying on the console
* Added suppress warning flag for spyOn(console)
* Nits
* Removed spy-on-console guard
* Fixed a potential source of false-positives in toWarnDev() matcher
Also updated (most of) ReactIncrementalErrorLogging-test.internal to use the new matcher
* Removed unused third param to spyOn
* Improved clarity of inline comments
* Removed unused normalizeCodeLocInfo() method
* enables ctrl + enter for keypress event on browsers other than firefox
* makes comment more descriptive as to affected platforms
* reverting fiber results
* Reset changes to results.json
* Remove old test file
* Add tests in the right place
* Move build/packages/* to build/node_modules/*
This fixes Node resolution in that folder and lets us require() packages in it in Node shell for manual testing.
* Link fixtures to packages/node_modules
This updates the location and also uses link: instead of file: to avoid Yarn caching the folder contents.
* Bump deps to Jest 22
* Prevent jsdom from logging intentionally thrown errors
This relies on our existing special field that we use to mute errors.
Perhaps, it would be better to instead rely on preventDefault() directly.
I outlined a possible strategy here: https://github.com/facebook/react/issues/11098#issuecomment-355032539
* Update snapshots
* Mock out a method called by ReactART that now throws
* Calling .click() no longer works, dispatch event instead
* Fix incorrect SVG element creation in test
* Render SVG elements inside <svg> to avoid extra warnings
* Fix range input test to use numeric value
* Fix creating SVG element in test
* Replace brittle test that relied on jsdom behavior
The test passed in jsdom due to its implementation details.
The original intention was to test the mutation method, but it was removed a while ago.
Following @nhunzaker's suggestion, I moved the tests to ReactDOMInput and adjusted them to not rely on implementation details.
* Add a workaround for the expected extra client-side warning
This is a bit ugly but it's just two places. I think we can live with this.
* Only warn once for mismatches caused by bad attribute casing
We used to warn both about bad casing and about a mismatch.
The mismatch warning was a bit confusing. We didn't know we warned twice because jsdom didn't faithfully emulate SVG.
This changes the behavior to only leave the warning about bad casing if that's what caused the mismatch.
It also adjusts the test to have an expectation that matches the real world behavior.
* Add an expected warning per comment in the same test
