These (from #4619 and #4625) are very similar and I'm also going to add
more cases to them in the next commit.
Also add similar tests to Instant and PlainTime.
The spec describes the internal representation of Duration as float64-
representable integers. There are a few tricky ways that it is
observable if an implementation does not do this correctly. Here are
some tests for them.
These tests confirm that Temporal-object-like property bags have the
correct default values for their optional properties.
This provides coverage for a V8 bug:
https://issues.chromium.org/issues/446728405
* Temporal: Add an overflow test for date addition with maximum year
* Add tests for other cases
* Fix minimum dates
* Add cases for adding/subtracting the negated duration to the opposite end of the allowed years
These tests cover the normative change approved in the July 2025 TC39
plenary. See https://github.com/tc39/proposal-temporal/pull/3130.
All properties of user-passed options objects should be read and cast
before any "algorithmic validation" is done.
This is a lot of tests, that cover every entry point where an options
object is passed in, where subsequently an exception can be thrown or user
code can be called.
However, the normative change only affects 10 of these tests:
- Instant.p.since,until,toString
- PlainDate.p.since,until
- PlainTime.p.since,until
- PlainYearMonth.p.since,until
- ZonedDateTime.p.toString
The other 35 tests simply close a gap in coverage.
See: tc39/proposal-temporal#3121
A type assertion in the spec was incorrect, but the assertion wasn't hit
in the Firefox implementation in any test262 test. These three tests add
coverage for all the paths that would have hit that assertion.
Changes made to:
- PlainDate
- PlainYearMonth
- ZonedDateTime
- PlainDateTime
- PlainMonthDay
Merged calendar-number.js and calendar-wrong-type.js, due to no special behaviour of number to be tested.
Extracted string tests to calendar-iso-string.js and renamed the file to calendar-invalid-iso-string.js, due to the contents of the file initially testing invalid ISO strings.
Closes#3873
Syntax is validated first. Only after the property bag is fully converted
into a Calendar Fields Record does the calendar validate whether the month
code actually exists in the year.
See tc39/proposal-temporal#2962
Remove the existing "instant-string-limits.js" that only applied to APIs
where ToTemporalInstant was called. Add "argument-string-limits.js" tests
everywhere ISO strings are converted.
Related to tc39/proposal-temporal#2985
Tweak some tests to provide coverage of new execution paths in the spec,
such as calling GetOptionsObject inside ToTemporal___; add a few new tests
for things that weren't covered before, such as rounding a PlainDateTime
at the edge of the range; and tweak the tests verifying when the
properties of the options bag are read, which I made a mistake in #4119.
See: https://github.com/tc39/proposal-temporal/pull/2925
Now that we don't have to deal with strings or objects as input to the
calendar ID or time zone ID parameter of constructors, we accept only the
data that actually goes into the internal slots.
Previously getISOFields() was used to get the exact value of the
[[Calendar]] and [[TimeZone]] internal slots, as well as to get the
reference ISO year for PlainMonthDay and reference ISO day for
PlainYearMonth.
Use calendarId and timeZoneId for the former and toString() for the
latter.
Without custom calendars and time zones there are actually a bunch of
things that we now can't test on implementations that don't have non-ISO
calendars or non-UTC time zones. (Alternatively, we can say that these are
functionalities that those implementations don't have to implement.)
These are no longer possible without custom objects. Also add an exception
for calendar and timeZone properties in property bag observers so they are
not treated as objects.
Many tests tested some functionality while asserting that there were no
calls of calendar or time zone methods. We can continue testing the
functionality, but there are no more methods to call, so we can delete
those parts of the tests.
It's no longer possible to fake built-in time zones using custom objects.
So testing DST shifts will have to use real built-in time zones. Replace
TemporalHelpers.springForwardFallBackTimeZone with America/Vancouver (it
was modelled on the DST transitions in 2000) and
TemporalHelpers.crossDateLineTimeZone with Pacific/Apia (it was modelled
on the 2011 switch to the other side of the international date line.)
These tests have to move to the intl402/ folder since non-Intl-aware
implementations are allowed (but not required) to support any built-in
time zones other than UTC.
In many cases we created a TimeZone or Calendar instance from a built-in
time zone or calendar. These tests can be trivially adapted to just use
the string ID.
Temporarily replace them with getISOFields().calendar/timeZone just to
keep the tests running until we remove Calendar and TimeZone objects
altogether.
See: tc39/proposal-temporal#2826
Following the upstream ECMA-402 change tested in the previous commit, add
test coverage for the corresponding functionality in Temporal. Fix one
test that was erroneous.
This should produce all the same results (except for a change to weeks
balancing in round(), which is now more consistent with since()/until())
but leads to different observable user code calls.
See https://github.com/tc39/proposal-temporal/issues/2742
These tests were supposed to test an invalid ISO string being used as the
`calendar` property in a property bag. Instead they were testing being
used as an invalid ISO string directly where a PlainDate input was needed.
(That is also already covered elsewhere.)
Due to overlooked copy-paste errors we were creating the wrong type of
instance in these tests, and therefore testing the wrong method.
(Add blank line for consistency with the other instances of these tests.)
With test cases kindly provided by Anba, this adds test coverage for the
abrupt completion in the last step of DifferenceTemporalPlainDateTime,
where the resulting Duration components have mixed signs.
See: https://github.com/tc39/proposal-temporal/issues/2783
As per IETF, annotation keys may only consist of lowercase letters,
dashes, and digits, and an optional leading underscore. Uppercase letters
are non-syntactical. Add tests covering this.
