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.
See tc39/proposal-temporal#2825.
Various edits to existing tests so that they make more sense with the
removal of relativeTo.
New tests specifically testing that calendar units cannot be added or
subtracted directly.
See tc39/proposal-temporal#2825. This is a mass removal of tests that use
this functionality, in a separate commit for ease of review. Further
adjustments will be made in the following commit.
This covers an edge case that we hit, where 24 hours would not balance up
to one day in a 25-hour day if only largestUnit was specified, but would
erroneously balance up if rounding was also performed by specifying
smallestUnit.
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
After rounding relative to a ZonedDateTime, we have to potentially adjust
for DST. With a time zone providing nonsensical values, the duration may
go out of range.
See: tc39/proposal-temporal#2801
This test isn't testing what the assertion message previously said it was
testing. The integer is allowed to be unsafe, but in this case its
float64-representation is out of range.
See: https://github.com/tc39/proposal-temporal/issues/2785
These test cases ensure that DST disambiguation does not take place on
intermediate values that are not the start or the end of the calculation.
Note that NormalizedTimeDurationToDays is no longer called inside
Temporal.Duration.prototype.add/subtract, so a few tests can be deleted.
Other tests need to be adjusted because NormalizedTimeDurationToDays is
no longer called inside Temporal.ZonedDateTime.prototype.since/until via
DifferenceZonedDateTime, although it is still called as part of rounding.
In addition, new tests for the now-fixed edge case are added, and for the
day corrections that can happen to intermediates.
See https://github.com/tc39/proposal-temporal/pull/2760
Adapts the tests that checked arbitrarily long loops, to now check that an
exception is thrown if the loop would happen.
Adds tests that exercise the newly added checks on return values of
getPossibleInstantsFor and getOffsetNanosecondsFor that limit UTC offset
shifts to 24 hours or less.
Also updates some step numbers in related tests.
The existing tests didn't cover some edge cases where implementations
have to compute the exact result of `numerator / denominator`, where at
least one of `numerator` and `denominator` can't be exactly represented
by an IEEE-754 double precision floating point value.
"precision-exact-mathematical-values-5.js" gets added in #3961, so the
new tests from this commit start at "precision-exact-mathematical-values-6.js".
NormalizedTimeDurationToDays can no longer loop indefinitely, because at
a certain point we will hit the upper bound of MAX_SAFE_INTEGER, so rename
the test to reflect that it can loop an arbitrary but limited number of
times.
Add a test for the RangeError condition in NormalizedTimeDurationToDays
when the time zone calculates a day length that is not a safe integer
number of nanoseconds.
While editing these tests, rename them to match the current name of the AO
and make sure the step numbers are up to date. (Normally I wouldn't care
so much about that, but these tests can be pretty confusing so it's good
to be able to refer to the spec text.)
Adapts or removes tests that relied on creating durations that are now out
of range. Adds new tests for maximum in-range and minimum out-of-range
durations.
A few results change because the algorithm previously used for rounding
didn't always add duration units to dates in RFC 5545 order, and we also
introduce a special case for rounding with largestUnit years or months and
smallestUnit weeks.
See https://github.com/tc39/proposal-temporal/issues/2563
The old behaviour was encoded in one test in staging, but the behaviour of
largestUnit in duration rounding has changed since that test was written.
Therefore I'm assuming that toString() should've been updated when that
happened.
In the AO DisambiguatePossibleInstants, a PlainDateTime instance is passed
to user code. This instance should have the built-in ISO 8601 calendar.
Here are some tests that ensure it does.
See tc39/proposal-temporal#2671.
This removes several loopholes where it was possible to return particular
values from user calls that would cause infinite loops, or calculate
zero-length days.
This allows removing several tests, as calendar.dateAdd() is no longer
called in several places, and it's no longer possible to create a
situation where BigInt arithmetic is observable in NanosecondsToDays.
