* 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 🤷

* Make sure contains are unlinked from the document even if the test fails
* Remove unnecessary findDOMNode calls
* Generate Flow config on install
We'll need to do pre-renderer Flow passes with different configs.
This is the first step to get it working. We only want the original version checked in.
* Create multiple Flow configs from a template
* Run Flow per renderer
* Lint
* Revert the environment consolidation
I thought this would be a bit cleaner at first because we now have non-environment files in this directory.
But Sebastian is changing these files at the same time so I want to avoid conflicts and keep the PR more tightly scoped. Undo.

```
* Installed 3.x release of react-lifecycles-compat
* Updated ReactComponentLifeCycle-test and ReactDOMServerLifecycles-test to cover both polyfilled lifecycles in StrictMode
* Updated StrictMode warnings to not warn about polyfilled getSnapshotBeforeUpdate
* New context API
Introduces a declarative context API that propagates updates even when
shouldComponentUpdate returns false.
* Fuzz tester for context
* Use ReactElement for provider and consumer children
* Unify more branches in createFiberFromElement
* Compare context values using Object.is
Same semantics as PureComponent/shallowEqual.
* Add support for Provider and Consumer to server-side renderer
* Store providers on global stack
Rather than using a linked list stored on the context type. The global
stack can be reset in case of an interruption or error, whereas with the
linked list implementation, you'd need to keep track of every
context type.
* Put new context API behind a feature flag
We'll enable this in www only for now.
* Store nearest provider on context object
* Handle reentrancy in server renderer
Context stack should be per server renderer instance.
* Bailout of consumer updates using bitmask
The context type defines an optional function that compares two context
values, returning a bitfield. A consumer may specify the bits it needs
for rendering. If a provider's context changes, and the consumer's bits
do not intersect with the changed bits, we can skip the consumer.
This is similar to how selectors are used in Redux but fast enough to do
while scanning the tree. The only user code involved is the function
that computes the changed bits. But that's only called once per provider
update, not for every consumer.
* Store current value and changed bits on context object
There are fewer providers than consumers, so better to do this work
at the provider.
* Use maximum of 31 bits for bitmask
This is the largest integer size in V8 on 32-bit systems. Warn in
development if too large a number is used.
* ProviderComponent -> ContextProvider, ConsumerComponent -> ContextConsumer
* Inline Object.is
* Warn if multiple renderers concurrently render the same context provider
Let's see if we can get away with not supporting this for now. If it
turns out that it's needed, we can fall back to backtracking the
fiber return path.
* Nits that came up during review
* Adds danger_js with an initial rule for warning about large PRs
Signed-off-by: Anandaroop Roy <roop@artsymail.com>
* [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
* 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.
* 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
* use different eslint config for es6 and es5
* remove confusing eslint/baseConfig.js & add more eslint setting for es5, es6
* more clear way to run eslint on es5 & es6 file
* seperate ESNext, ES6, ES6 path, and use different lint config
* rename eslint config file & update eslint rules
* Undo yarn.lock changes
* Rename a file
* Remove unnecessary exceptions
* Refactor a little bit
* Refactor and tweak the logic
* Minor issues
* Rewrite the build scripts
* Don't crash when doing FB-only builds
* Group sync imports under Sync.*
* Don't print known errors twice
* Use an exclamation that aligns vertically
* Change build process to include npm pack and unpacking generated packages to corresponding build directories.
* Update function name, change to use os's default temp directory
* appending uuid to temp npm packaging directory.
* Unify the way we fork modules
* Replace rollup-plugin-alias with our own plugin
This does exactly what we need and doesn't suffer from https://github.com/rollup/rollup-plugin-alias/issues/34.
* Move the new plugin to its own file
* Rename variable for consistency
I settled on calling them "forks" since we already have a different concept of "shims".
* Move fork config into its own file
* Add bundle linting and tests to the release script
- add yarn lint-build
- use yarn lint-build in circle ci build.sh
- add yarn lint-build, yarn test-prod, yarn test-build, and yarn test-build-prod to the realse script
* Improve readability of release test messages
* Run prettier
* Updating package versions for release 16.2.0
* Seperate bundle specific tests
- Moved the runYarnTask into utils since its being used two files now
- Uncomment out checks I mistakenly committed
* Revert a bunch of version bump changes
Mistakenly commited by release script
* .js for consistency
* Extract Jest config into a separate file
* Refactor Jest scripts directory structure
Introduces a more consistent naming scheme.
* Add yarn test-bundles and yarn test-prod-bundles
Only files ending with -test.public.js are opted in (so far we don't have any).
* Fix error decoding for production bundles
GCC seems to remove `new` from `new Error()` which broke our proxy.
* Build production version of react-noop-renderer
This lets us test more bundles.
* Switch to blacklist (exclude .private.js tests)
* Rename tests that are currently broken against bundles to *-test.internal.js
Some of these are using private APIs. Some have other issues.
* Add bundle tests to CI
* Split private and public ReactJSXElementValidator tests
* Remove internal deps from ReactServerRendering-test and make it public
* Only run tests directly in __tests__
This lets us share code between test files by placing them in __tests__/utils.
* Remove ExecutionEnvironment dependency from DOMServerIntegrationTest
It's not necessary since Stack.
* Split up ReactDOMServerIntegration into test suite and utilities
This enables us to further split it down. Good both for parallelization and extracting public parts.
* Split Fragment tests from other DOMServerIntegration tests
This enables them to opt other DOMServerIntegration tests into bundle testing.
* Split ReactDOMServerIntegration into different test files
It was way too slow to run all these in sequence.
* Don't reset the cache twice in DOMServerIntegration tests
We used to do this to simulate testing separate bundles.
But now we actually *do* test bundles. So there is no need for this, as it makes tests slower.
* Rename test-bundles* commands to test-build*
Also add test-prod-build as alias for test-build-prod because I keep messing them up.
* Use regenerator polyfill for react-noop
This fixes other issues and finally lets us run ReactNoop tests against a prod bundle.
* Run most Incremental tests against bundles
Now that GCC generator issue is fixed, we can do this.
I split ErrorLogging test separately because it does mocking. Other error handling tests don't need it.
* Update sizes
* Fix ReactMount test
* Enable ReactDOMComponent test
* Fix a warning issue uncovered by flat bundle testing
With flat bundles, we couldn't produce a good warning for <div onclick={}> on SSR
because it doesn't use the event system. However the issue was not visible in normal
Jest runs because the event plugins have been injected by the time the test ran.
To solve this, I am explicitly passing whether event system is available as an argument
to the hook. This makes the behavior consistent between source and bundle tests. Then
I change the tests to document the actual logic and _attempt_ to show a nice message
(e.g. we know for sure `onclick` is a bad event but we don't know the right name for it
on the server so we just say a generic message about camelCase naming convention).
* Remove global mocks
They are making it harder to test compiled bundles.
One of them (FeatureFlags) is not used. It is mocked in some specific test files (and that's fine).
The other (FiberErrorLogger) is mocked to silence its output. I'll look if there's some other way to achieve this.
* Add error.suppressReactErrorLogging and use it in tests
This adds an escape hatch to *not* log errors that go through React to the console.
We will enable it for our own tests.
