* Remove event simulation of onChange events
It’s time to get rid of even more `ReactTestUtils.Simulate`s. In this PR
we remove the event simulation from all onChange tests. To do this, we
have to get a setter to the untracked value/checked props.
All remaining `ReactTestUtils.Simulate` calls are either testing
ReactTestUtils or assert that they do/don't throw.
* Use input instead of change event for all but checkbox, radio, and select
* 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 🤷

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

* 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
* 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()
* Ensure value and defaultValue do not assign functions and symbols
* Eliminate assignProperty method from ReactDOMInput
* Restore original placement of defaultValue reservedProp
* Reduce branching. Make assignment more consistent
* Control for warnings in symbol/function tests
* Add boolean to readOnly assignments
* Tweak the tests
* Invalid value attributes should convert to an empty string
* Revert ChangeEventPlugin update. See #11746
* Format
* Replace shouldSetAttribute call with value specific type check
DOMProperty.shouldSetAttribute runs a few other checks that aren't
appropriate for determining if a value or defaultValue should be
assigned on an input. This commit replaces that call with an input
specific check.
* Remove unused import
* Eliminate unnecessary numeric equality checks (#11751)
* Eliminate unnecessary numeric equality checks
This commit changes the way numeric equality for number inputs works
such that it compares against `input.valueAsNumber`. This eliminates
quite a bit of branching around numeric equality.
* There is no need to compare valueAsNumber
* Add test cases for empty string to 0.
* Avoid implicit boolean JSX props
* Split up numeric equality test to isolate eslint disable command
* Fix typo in ReactDOMInput test
* Add todos
* Update the attribute table
* Use defaultValue instead of setAttribute('value')
This commit replaces the method of synchronizing an input's value
attribute from using setAttribute to assigning defaultValue. This has
several benefits:
- Fixes issue where IE10+ and Edge password icon disappears (#7328)
- Fixes issue where toggling input types hides display value on dates
in Safari (unreported)
- Removes mutationMethod behaviors from DOMPropertyOperations
* initialValue in Input wrapperState is always a string
* The value property is assigned before the value attribute. Fix related tests.
* Remove initial value tests in ReactDOMInput
I added these tests after removing the `value` mutation
method. However they do not add any additional value over existing
tests.
* Improve clarity of value checks in ReactDOMInput.postMountWrapper
* Remove value and defaultValue from InputWithWrapperState type
They are already included in the type definition for HTMLInputElement
* Inline stringification of value in ReactDOMInput
Avoids eagier stringification and makes usage more consistent.
* Use consistent value/defaultValue presence in postMountHook
Other methods in ReactDOMInput check for null instead of
hasOwnProperty.
* Add missing semicolon
* Remove unused value argument in ReactDOMInput test
* Address cases where a value switches to undefined
When a controlled input value switches to undefined, it reverts back
to the initial state of the controlled input.
We didn't have test coverage for this case, so I've added two describe
blocks to cover both null and undefined.
* 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.

We used to before, too. I just forgot to add the arguments after deleting the script.
Fixes a case where changing the name and checked value of a radio button in the same update would lead to checking the wrong radio input. Also adds a DOM test fixture for related issue.

This uncovered an interesting problem where ./b from package/src/a would resolve to a different instantiation of package/src/b in Jest.
Either this is a showstopper or we can solve it by completely fobbidding remaining /src/.
* Fix all tests
It seems we can't use relative requires in tests anymore. Otherwise Jest becomes confused between real file and symlink.
https://github.com/facebook/jest/issues/3830
This seems bad... Except that we already *don't* want people to create tests that import individual source files.
All existing cases of us doing so are actually TODOs waiting to be fixed.
So perhaps this requirement isn't too bad because it makes bad code looks bad.
Of course, if we go with this, we'll have to lint against relative requires in tests.
It also makes moving things more painful.
