* 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.
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.
This test started failing when updating to ICU 64, because ICU supports "zh"
and "zh-Hans-CN", but not explicitly also "zh-Hans", which is required for this
test to pass. The same kind of error is reproducible with ICU <64 when "Guru"
is added to the list of script codes in 'testIntl.js', because ICU supports
"pa-Guru-IN", but "pa-IN" isn't explicitly supported, too.
So, change this test to also check 'byFallback' to see if a locale is supported.
Drive-by change:
- Modernise the test to make it more readable how subtags are combined.
- Also add "419" to the list of region codes to cover the digit region syntax.
harness/testIntl.js
- Add now invalid tags to getInvalidLanguageTags, these tags were previously used in test files changed in this commit.
- Update isCanonicalizedStructurallyValidLanguageTag regular expressions.
test/intl402/Intl/getCanonicalLocales/canonicalized-tags.js
- Moved five now invalid tags to getInvalidLanguageTags function in testIntl.js
test/intl402/Intl/getCanonicalLocales/preferred-grandfathered.js
- All irregular grandfathered tags are invalid now
- Regular grandfathered with extlang subtags are now also invalid
- Regular grandfathered with variant-like subtags are still valid
test/intl402/Intl/getCanonicalLocales/weird-cases.js
- Revert changes from last commit
- "x-u-foo" is now invalid and was moved to getInvalidLanguageTags function
test/intl402/ListFormat/constructor/constructor/locales-valid.js
test/intl402/RelativeTimeFormat/constructor/constructor/locales-valid.js
test/intl402/Segmenter/constructor/constructor/locales-valid.js
- Irregular grandfathered and privateuse only are no longer valid language tags
test/intl402/language-tags-canonicalized.js
- Same changes as in test/intl402/Intl/getCanonicalLocales/canonicalized-tags.js
test/intl402/language-tags-invalid.js
- Invalid tags list in this file was a subset of getInvalidLanguageTags, so replaced with getInvalidLanguageTags to get more coverage
test/intl402/language-tags-valid.js
- Same changes as in test/intl402/Intl/getCanonicalLocales/canonicalized-tags.js
* Add Intl.RelativeTimeFormat feature.
* Add tests for the shape of the Intl.RelativeTimeFormat API.
* fixup! Add tests for the shape of the Intl.RelativeTimeFormat API.
