This contains tests for the normative PR
https://github.com/tc39/proposal-temporal/pull/2437, which is to be
presented for consensus to TC39 in the upcoming plenary meeting. That PR
changes the observable order of property accesses to be alphabetical where
possible.
This reconciles changes made in two normative PRs to the Temporal proposal
which each had their own separate PRs for tests. The yearOfWeek tests were
written before the changes to the ISO 8601 grammar which disallowed the
YYYY-MM-DD+UU format. This brings the yearOfWeek tests in line with the
tests for the other calendar methods.
As per the discussion in
https://github.com/tc39/proposal-temporal/issues/2379#issuecomment-1248557100
and the PR https://github.com/tc39/proposal-temporal/pull/2398, which is
to be presented for consensus to TC39 in the upcoming plenary meeting, UTC
offsets and the Z designator should be disallowed after any date-only
strings (YYYY-MM-DD, YYYY-MM, and MM-DD). They should only be allowed to
follow a time component. Z remains disallowed in any string being parsed
into a Plain type.
Annotations become allowed after any ISO string, even YYYY-MM and MM-DD
where they were previously disallowed.
To be presented for consensus in the November/December TC39 meeting. This
adds tests for a 'yearOfWeek' getter to PlainDate, PlainDateTime, and
ZonedDateTime, for use alongside 'weekOfYear', and tests for a
corresponding method to Calendar.
The tests are basically the existing tests of 'weekOfYear' adapted.

This contains tests for the normative PR
https://github.com/tc39/proposal-temporal/pull/2433, which is to be
presented for consensus to TC39 in the upcoming plenary meeting. That PR
changes ToTemporalCalendar to throw when it encounters a Temporal.TimeZone
instance, and ToTemporalTimeZone to throw when it encounters a
Temporal.Calendar instance.
We already have a similar test covering TimeZone.id that ensures toString
is not called. We did not have this coverage yet for Calendar.id, so adapt
the TimeZone test for Calendar.
This adds order-of-operations tests that cover all of the Temporal entry
points that accept options bags, that were not already covered. We'll be
using these tests in the future to verify
https://github.com/tc39/proposal-temporal/issues/2254
However, the tests in this commit reflect the current state of the
proposal, not the potential normative change.
Some of the existing order-of-operations tests didn't observe the calendar
operations. Add a TemporalHelpers.calendarObserver() calendar to the
invocations of these methods in the order-of-operations tests.
Some of the existing order-of-operations tests didn't pass an options bag:
primarily from(), with(), add() and subtract(). (since() and until() were
covered in a previous commit.)
Add a TemporalHelpers.propertyBagObserver() options bag to the invocations
of these methods in the order-of-operations tests.
The `relativeTo` parameter in an options bag may be undefined, a PlainDate
instance, or a ZonedDateTime instance. Each of these three possibilities
causes a different set of observable operations, which we can test in our
existing order-of-operations tests.
There are additional observable operations that occur when providing an
`offset` property in a relativeTo or ZonedDateTime property bag. We can
test these in our existing order-of-operations tests.
Use the new collections of strings in TemporalHelpers.ISO to add more
tests for ISO strings in API entry points that convert an ISO string to
Temporal.PlainYearMonth or Temporal.PlainMonthDay.
The idea is to deduplicate more string tests into methods on this object,
that return collections of valid and invalid strings. This adds
collections of valid and invalid PlainYearMonth and PlainMonthDay strings.
This tests the normative changes in
https://github.com/tc39/proposal-temporal/pull/2245, which achieved
consensus in the July 2022 TC39 meeting, specifically as they apply to the
Temporal.Calendar.prototype.mergeFields method.
Due to the use of the pre-existing spec operation CopyDataProperties, now
symbol keys are merged into the return value, and the order of observable
property operations has changed from a batch of [[GetOwnProperty]]
followed by a batch of [[Get]], to a series of interleaved
[[GetOwnProperty]]/[[Get]] pairs.

consensus in the July 2022 TC39 meeting, specifically as they apply to
places where the MergeLargestUnitOperation was called.
Due to the use of the pre-existing spec operation CopyDataProperties, the
order of observable property operations has changed from a batch of
[[GetOwnProperty]] followed by a batch of [[Get]], to a series of
interleaved [[GetOwnProperty]]/[[Get]] pairs. This previously wasn't
tested because TemporalHelpers.propertyBagObserver didn't track
[[GetOwnProperty]] operations, but now it does.
Using assert.deepEqual was faulty here, since deepEqual doesn't take
symbol keys into account. This test wasn't actually testing that the
symbol keys were absent, and in fact passes if they are present.
(Rather than fixing deepEqual, since we hope to deprecate it as per
https://github.com/tc39/test262/issues/3476, add a custom assert function
in the test.)
Normally, a plain object passed into an API that takes a Temporal.TimeZone
has its 'timeZone' property checked (observably) with a Has operation
followed by a Get operation if the property is present. In the normative
change https://github.com/tc39/proposal-temporal/pull/2392 which reached
consensus at the September 2022 TC39 meeting, this was changed so that
this check is skipped for objects which have the Temporal.TimeZone
internal slots.
This adds tests to all entry points that pass a user-supplied object to
ToTemporalTimeZone, with a "poisoned" timeZone object which has the
correct internal slots but a 'timeZone' accessor property whose getter
throws. A correct implementation should not cause this getter to throw.

In these tests, we should make a distinction in the name for clarity. It's
testing a time zone passed as a property in a property bag (either as an
argument, or as a relativeTo option), so name it accordingly as we do with
other tests in the same folder.
See https://github.com/tc39/proposal-temporal/pull/2316 which eliminated
an observable call to Array.prototype[Symbol.iterator]() in the case where
a calendar's 'fields' property was undefined.
The best way I've thought of to test this is to monkeypatch the
Array.prototype[Symbol.iterator]() method to make it throw. In some cases,
where we are actually expected to iterate the return value from a
Temporal.TimeZone's getPossibleInstantsFor() method, we have to provide a
custom method for that as well, that returns a non-Array iterable so we
don't call the patched Array.prototype[Symbol.iterator]().
This normative change reached consensus at the July 2022 TC39 plenary
meeting.
The programmer always gets the last word over how the string is
interpreted, since otherwise it's not possible to make any guarantees
about the offset option. (This is the "out-of-band" mechanism mentioned in
the IETF draft.) Add a test for this.
Based on the improvements just made to the calendarName option, improve
the tests for the timeZoneName option of ZonedDateTime.prototype.toString
as well.
Since we are going to be adding a new test for calendarName: "critical",
take the existing tests for various values of the calendarName option, and
regularize them. Previously, depending on which type's toString() method
was under test, the tests had various degrees of thoroughness, and some
were only present in staging.
See https://github.com/tc39/proposal-temporal/pull/2397
Adds tests for ISO strings with more than one time zone annotation. These
are not syntactically correct according to the grammar and should be
rejected.
See https://github.com/tc39/proposal-temporal/pull/2397
Adds tests for ISO strings with unrecognized annotations, (i.e., neither
time zone nor calendar), in various combinations with recognized
annotations.
See https://github.com/tc39/proposal-temporal/pull/2397
Adds tests for ISO strings with calendar annotations, with and without the
critical flag, and also a check that the second calendar annotation is
disregarded, as per the IETF draft.
See https://github.com/tc39/proposal-temporal/pull/2397
Adds tests for ISO strings with named and numeric offset time zone
annotations, with and without the critical flag, with various combinations
of Z and offset in front of the annotation.
As of https://github.com/tc39/proposal-temporal/pull/2397 which reached
consensus in the August 2022 TC39 meeting, a date-time + Z with no bracket
annotation is no longer accepted as a relativeTo parameter; either the Z
should be removed or a bracket annotation should be added.
This requires adjusting a few existing tests, but doesn't require any new
ones.
See https://github.com/tc39/proposal-temporal/pull/2267 which eliminated
some unnecessary lookups of the calendar's dateAdd method from the
MoveRelativeDate AO, which is called in the calendar types' since() and
until() methods, Duration.p.round(), and Duration.p.total().
This adds tests for the order of all observable operations for these 10
methods, not just the lookups of dateAdd on the calendar. (These methods
needed to have their order of observable operations tested anyway.)
They heavily use the TemporalHelpers.calendarObserver and
TemporalHelpers.timeZoneObserver added in the previous commits.
https://github.com/tc39/proposal-temporal/pull/2267 included changes to
several code paths, not all of which are reachable through every method
tested here; only Duration.p.round() can trigger the full set.
https://github.com/tc39/proposal-temporal/pull/2267 reached consensus at
the July 2022 TC39 plenary meeting.
Similar to the previous commits with property bags and time zones, there
are also some existing tests that use a Proxy to test the order of
observable operations which involve user code
passed in as part of a Temporal.TimeZone object. I am going to write
several more tests that do this, as well. This seems like a good thing to
put into TemporalHelpers, where it can be implemented consistently so that
we don't get discrepancies in which operations are tracked, or bugs due to
a Symbol-valued property.
Updates existing tests to use this helper.

This adds tests for the normative change in tc39/proposal-temporal#2265,
which adds validation steps to certain abstract operations that call
Temporal.Calendar methods.
These had some duplication with some existing tests named
calendar-returns-infinity.js. Remove these, because the new tests are more
complete in testing what values are accepted.
The existing tests would fail after making the normative change from
tc39/proposal-temporal#2265 because they rely on the getter directly
returning whatever value the calendar method returned. This is no longer
the case, because the value returned by the calendar is validated, so
adjust the assertions in these tests.
Also, no longer any need to return a value from the calendar method that
needs to be converted; we'll add separate tests for that.
Expand these tests to cover all of the PlainDate, PlainDateTime,
PlainMonthDay, PlainYearMonth, and ZonedDateTime property getters that
delegate to the calendar methods.

The "half___" modes all round to the nearest increment except when there
is a tie. The previous tests didn't test rounding in the case of any ties
(except for .toString()) so here we use some different numbers in which
there is a tie, in order to make tests where the "half___" modes are more
thoroughly tested.
See https://github.com/tc39/proposal-temporal/pull/2262 which added new
rounding modes from NumberFormat V3.
See https://github.com/tc39/proposal-temporal/pull/2262 which added new
rounding modes from NumberFormat V3.
These tests use the same format as the previous ones. The tests for the
"half" rounding modes aren't very good yet, as they don't show any of the
differences between the tiebreaking schemes; there aren't any ties in the
data to be broken. (Except in .toString().) A subsequent commit will
correct this.
