* Temporal.now.plainDateTime: import tests from prop
* Add required metadata
* Correct invalid test
Ensure the error is thrown due to the invocation of the provided method.
Add a separate test to verify how the method is invoked.
* Remove duplicated assertions
* Improve coverage
* Rewrite test to focus on Calendar parameter
The observable interactions with the "timeZone" parameter are verified
by another test which is named for that purpose.
* Remove non-standard test
This test's title suggests that it was intended to verify the behavior
when the "calendar" parameter was undefined. The expected behavior in
that case depends on the presence of a builtin calendar named
"undefined." Test262 cannot definitively assert the presence or absence
of such a calendar.
In contrast to the title, the test body actually uses the calendar name
"japanese." Test262 cannot definitively assert the presence or absence
of such a calendar.
* Fix test for only {localeMatcher: "lookup"}
The expectation that "sr-Thai-RS" would be returned is only true with the
9.2.2 BestAvailableLocale ( availableLocales, locale )
https://tc39.es/ecma402/#sec-bestavailablelocale
algorithm used by 9.2.3 LookupMatcher ( availableLocales, requestedLocales )
https://tc39.es/ecma402/#sec-lookupmatcher
The default for localeMatcher is "best fit" but not "lookup" for all Intl objects.
And for 9.2.4 BestFitMatcher ( availableLocales, requestedLocales )
https://tc39.es/ecma402/#sec-bestfitmatcher
It may not match "sr-Thai-RS" for "sr" and return ["de", "zh-CN"] instead. Therefore, we need to change this test to only test on {localeMatcher: "lookup"}
* Add option to getLocaleSupportInfo
Needed to test different localeMatcher
* only test for "lookup" localeMatcher
* Get the info based on the localeMatcher
* pass in localeMatcher to getLocaleSupportInfo
This code is setting values to $1 etc., which can be non-writable or accessors.
For example, https://github.com/tc39/proposal-regexp-legacy-features/ is specifying them as accessors, and they should throw an error when
it is done in strict code. We should execute `(/(?:)/).test("");` to clear them.
The WeakRefs proposal advanced to Stage 4 but cleanupSome moved back to a Stage 2 status.
The tests should remain in Test262 for now but this feature flag should help users to
filter tests out.
Verify that every test file which references a harness file using the
"includes" directive also contains at least one reference to a value
defined in the harness file.
To support this check, extend each harness file with a list of values
which it defines.
