This adds tests specifically for every kind of case that changes due to
the tweak to the date difference algorithm: differences from a longer
month to a shorter month, when the months are adjacent, in the same year
but not adjacent, and in different years.
Also adds tests for a case that does *not* change, but would trip on an
incorrectly implemented algorithm: when the intermediate months value
falls at the end of February.
There was incidental coverage of the change to the date difference
algorithm in other tests. Those are adjusted, as well.

Consensus in February 2024
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.
In order to fixtc39/proposal-temporal#2563, we added invocations of
BalanceDurationRelative after some invocations of RoundDuration. These
cause observable calendar calls, which must be accounted for in some
existing tests.
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.
Note the monkeypatch of getPossibleInstantsFor in test/built-ins/Temporal/
TimeZone/prototype/getInstantFor/argument-builtin-calendar-no-array-
iteration.js.
Other than that, all the tests are basically identical.
Adds new tests to order-of-operations.js in Duration.round and
Duration.total, to exercise the code path where previous to this normative
change, relativeTo would have been converted to PlainDate 3x and 2x,
respectively.
This shortcut path now exists in all round(), since(), and until()
operations.
In Instant, PlainDate, PlainDateTime, and PlainTime, the change isn't
observable, so no tests could be added. This adds test coverage for
- Duration.p.round()
- PlainYearMonth.p.since()
- PlainYearMonth.p.until()
- ZonedDateTime.p.round()
- ZonedDateTime.p.since()
- ZonedDateTime.p.until()
As well as a few cases where we are testing that certain calendar methods
get called during a round operation, but previously were doing so with
options that now become a no-op and no longer call those calendar methods.
In those cases, round to 2 ns, rather than 1 ns.
This commit verifies that ISO strings with sub-minute offsets cannot
be parsed into time zone identifiers. This was a change introduced in
the recently-merged tc39/proposal-temporal#2607, but tests for this case
were missing from #3862 (the tests for that PR).
I noticed in codecov results on an unrelated PR that this case wasn't
being tested, so fixing that mistake now.
Codecov showed that PlainTime strings like "09:00:00Z[UTC]" or
"09:00:00Z" were not being tested. This commit fills that gap.
It'd probably be good to make similar changes for other Plain* types,
but Codecov didn't complain about them so they may be covered
via other tests so it was less urgent.
This commit fills a test hole found by Codecov: we weren't checking for
the case of a custom time zone whose `id` property returns a non-string
value.
Note that the `id` property is only read in a few places, all on the
ZonedDateTime prototype: `until`, `since`, `equals`, `toString`,
`toLocaleString`, `toJSON`, and `timeZoneId`.
Edits Temporal tests to account for changes in
https://github.com/tc39/proposal-temporal/pull/2574.
This PR stops coercing non-string primitive inputs to strings
in Temporal methods, to avoid cases where numbers
are coerced to syntactically valid but often unexpected
string results.

As per IETF review, an IXDTF string (ISO 8601 with annotations) is no
longer valid if it contains more than one u-ca annotation and at least one
of the annotations is marked critical.
Removes tests where such a string was assumed to be valid, and adds new
ones with a few variations on invalid strings.
Add order-of-operations tests for:
- Temporal.ZonedDateTime.p.getISOFields()
- Temporal.ZonedDateTime.p.round()
- years with ZonedDateTime relativeTo in Temporal.Duration.p.round()
- years with ZonedDateTime relativeTo in Temporal.Duration.p.total()
- property Gets on receiver in Temporal.PlainDateTime.p.with()
- ZonedDateTime difference methods with largestUnit being a time unit
- Duration.compare with no units higher than hours
