Same as before, just use don't use prefixes, since they pretty match useless now
and use page visibility API to determine if animation should start.
Also null the requestAnimationFrame attribute in window for tests since
sinon does not provide fake method for it.
Fixes#15147
* Removed inline usage of QUnit.reset() because it is messing with the
expectation model as reset does .empty() which does a recursive cleanData
on everything in #qunit-fixture, so any expectJqData above .reset() would
fail negatively.
Instead of calling reset inline, either updated the following assertions to
take previous assertions' state into account, or broke the test() up into
2 tests at the point where it would call QUnit.reset.
* After introducing the new memory leak discovery a whole bunch of tests were
failing as they didn't clean up everything. However I didn't (yet) add
QUnit.expectJqData calls all over the place because in most if not all of
these cases it is valid data storage. For example in test "data()", there
will be an internal data key for "parsedAttrs". This particular test isn't
intending to test for memory leaks, so therefor I made the new discovery
system only push failures when the test contains at least 1 call to
QUnit.expectJqData.
When not, we'll assume that whatever data is being stored is acceptable
because the relevant elements still exist in the DOM anyway (QUnit.reset
will remove the elements and clean up the data automatically).
I did add a "Always check jQuery.data" mode in the test suite that will
trigger it everywhere. Maybe one day we'll include a call to everywhere,
but for now I'm keeping the status quo: Only consider data left in storage
to be a problem if the test says so ("opt-in").
* Had to move #fx-tests inside the fixture because ".remove()" test would
otherwise remove stuff permanently and cause random other tests to fail
as "#hide div" would yield an empty collection.
(Why wasn't this in the fixture in the first place?)
As a result moving fx-tests into the fixture a whole bunch of tests failed
that relied on arbitrary stuff about the document-wide or fixture-wide
state (e.g. number of divs etc.). So I had to adjust various tests to
limit their sample data to not be so variable and unlimited...
* Moved out tests for expando cleanup into a separate test.
* Fixed implied global variable 'pass' in effects.js that was causing
"TypeError: boolean is not a function" in *UNRELATED* dimensions.js that
uses a global variable "pass = function () {};" ...
* Removed spurious calls to _removeData. The new test exposed various failures
e.g. where div[0] isn't being assigned any data anyway.
(queue.js and attributes.js toggleClass).
* Removed spurious clean up at the bottom of test() functions that are
already covered by the teardown (calling QUnit.reset or removeClass to
supposedly undo any changes).
* Documented the parentheses-less magic line in toggleClass. It appeared that
it would always keep the current class name if there was any (since the
assignment started with "this.className || ...".
Adding parentheses + spacing is 8 bytes (though only 1 in gzip apparently).
Only added the comment for now, though I prefer clarity with logical
operators, I'd rather not face the yayMinPD[1] in this test-related commit.
* Updated QUnit urlConfig to the new format (raw string is deprecated).
* Clean up odd htmlentities in test titles, QUnit escapes this.
