Adds a test similar to the one in #3697, but in the main tree.
The six code points in this test have an "F" for full case mapping in
CaseFolding.txt, and so they should not be considered in the
Canonicalize operation.
Current versions of SpiderMonkey and V8 fail this test, others pass.
These tests should cover the full functionality of the .groups object (and
the .indices.groups object, in the case of the /d flag) for RegExp.p.exec
and String.p.match:
- Matched DNCG has a result
- Unmatched DNCG is present and undefined
- DNCG matched in previous iteration but not in current iteration is
treated as unmatched
- Iteration order of properties corresponds with source order
See: #3704
Each named capturing group should count as its own parenthesized capturing
group, even if it has the same name as another group. So, some of these
expectations were missing `undefined` array elements for the variant of
the `x` capturing group that didn't match.
In the other expectations, we forgot to take into account that the
backreference is not inside a capturing group, so the group match should
not have doubled letters in it.
Parse-time syntax for RegExp literals is already tested. These two files
test runtime RegExp compilation, with respect to duplicate named capture
groups.

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.
This tests some of 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
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.
Normally, a plain object passed into an API that takes a Temporal.Calendar
has its 'calendar' 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.Calendar
internal slots.
This adds tests to all entry points that pass a user-supplied object to
ToTemporalCalendar, with a "poisoned" calendar object which has the
correct internal slots but a 'calendar' 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.
This adds tests to WeakMap, WeakSet, WeakRef, and FinalizationRegistry for
Symbols as weakly-held values. Regular symbols and well-known symbols are
both tested. These tests correspond to existing tests for Objects as
weakly-held values, but are put in separate files so that they can be
filtered out with the "symbols-as-weakmap-keys" feature flag.
Registered symbols are not allowed; this is already tested in the "cannot-
be-held-weakly" tests.
See: #2850
There are many existing tests for WeakMap, WeakSet, WeakRef, and
FinalizationRegistry using Objects as weak values. For symbols-as-weakmap-
keys, we'll want to write tests that parallel these for Symbol keys.
Change the descriptions and filenames of these tests to describe their new
scope of only Object weak values.
Update the front matter of these tests while we're at it, to reflect the
changes to the spec text that the symbols-as-weakmap-keys brings in. (In
some cases, remove irrelevant bits of the front matter.)
See: #2850
WeakMap, WeakSet, WeakRef, and FinalizationRegistry all had tests
verifying what would happen if they were called with a value that wasn't
allowed as a weak value: before this proposal, that was a non-Object.
Now, allowed weak values are Objects, well-known Symbols, and unregistered
Symbols. That leaves registered Symbols that are still not allowed as weak
values.
This commit updates those tests to use a registered Symbol instead of an
unregistered Symbol; they should still pass, regardless of whether the
implementation has implemented symbols-as-weakmap-keys yet.
The tests are renamed as appropriate.
Also updates the frontmatter to the most current spec text, including the
CanBeHeldWeakly abstract operation.
See: #2850
This test is duplicated by WeakSet/prototype/add/value-not-object-throw.js
Originally taken from Rick's draft commit for symbols-as-weakmap-keys
tests.
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.
Take all the existing tests for round() calculations using different
rounding modes and standardize them. Add tests for Duration, Instant and
ZonedDateTime, which were still in the old format in staging.
Take all the existing tests for since/until calculations using different

ZonedDateTime, which were still in the old format in staging.
See https://github.com/tc39/proposal-temporal/pull/2262, which reached
consensus in the July 2022 TC39 meeting. This change added several
rounding modes from the NumberFormat V3 proposal, some of which were
listed as invalid in the roundingmode-invalid-string tests. Remove these
items from the list of invalid modes, since they are no longer invalid.
Many existing tests use a Proxy to test the order of observable operations
on a property bag argument that gets passed in to a Temporal API. 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. (For example, we had some tests which didn't test for an ownKeys
operation that was supposed to be there.)
Updates existing tests to use this helper.
We did this inconsistently in PlainDate and ZonedDateTime, and not in the
other calendar-carrying types. Additionally, we don't have to create the
calendar explicitly in PlainDate.
This tests the normative change from
https://github.com/tc39/proposal-temporal/pull/2260
which achieved consensus in the July 2022 TC39 meeting.
The return value from a userland getOffsetNanosecondsFor method is no
longer allowed to be exactly one 24-hour day.
This adds tests that validate a user-callable getOffsetNanosecondsFor to
several APIs that didn't test this yet: ZonedDateTime.since/until, and
Calendar.era/eraYear.
In order for some tests to ensure that they are testing the right
exception, we need to make sure we are in the path where there are no
possible instants for a particular date-time. Override this method in some
tests.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2377 which reached
consensus at the September 2022 TC39 meeting.
It changes the order in which observable operations are performed on the
values passed to the ___fromFields methods of Calendar.
This adds an object, TemporalHelpers.ISO, which has methods that return
arrays of various ISO strings. The idea is to deduplicate more string
tests into methods on this object.

designator for disambiguation, are not disambiguated by adding a calendar
annotation.
This implements the normative change in

consensus at the July 2022 TC39 meeting.
It adds tests that ensure strings like HHMM-UU[TZ] and HHMMSS[TZ] do not
require a disambiguating T separator, even if HHMM-UU and HHMMSS would by
themselves.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2344 which reached
consensus at the July 2022 TC39 meeting.
It adds a test that catches a corner case in Duration.prototype.round().
For completeness, as we are doing in newer brand checking tests such as
those of Temporal, call these getters with a function object and a bigint
as the receiver.
Suggested in https://github.com/tc39/test262/pull/3614/files#r929662337
The intention of this test is to ensure that all built-in properties of
the global object are also exposed on the ShadowRealm's global object,
without penalizing implementations that don't have all of them
implemented.
Notably, SharedArrayBuffer may still not be (re-)enabled in all
circumstances.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2269 which reached
consensus at the July 2022 TC39 meeting.
There was already a test for PlainDate for this topic, which needs to be
adjusted to accommodate the normative change. Tests for PlainDateTime and
ZonedDateTime did not yet exist, so add new ones based on the PlainDate
test.
There are already tests to reject negative day lengths, so we can simply
remove these other tests.
Also remove a misleading comment ("Test negative divisor"), because the
test following the comment actually uses a positive divisor.

As of https://github.com/tc39/proposal-temporal/pull/2219 the arguments to
the calendar.mergeFields() methods should be null-prototype objects when
called from with() and toPlainDate() methods. This adds tests for that
behaviour.
As of https://github.com/tc39/proposal-temporal/pull/2219 the object
returned from the PrepareTemporalFields abstract operation should be a
null-prototype object. There are a number of places where this is
observable in one of the calendar's ...FromFields() methods. This adds
tests for this behaviour everywhere it is observable.
As of https://github.com/tc39/proposal-temporal/pull/2219 PlainYearMonth's
add() and subtract() methods should be calling the calendar's
yearMonthFromFields() method with a null-prototype object as the options
parameter, due to the change in
AddDurationToOrSubtractDurationFromPlainYearMonth. This adds a test for
this behaviour.
As of https://github.com/tc39/proposal-temporal/pull/2219 since() and
until() methods should be calling the calendar's dateUntil() method with a
null-prototype object as the options parameter, due to the change in
MergeLargestUnitOption. This adds a test for this behaviour.

The options-invalid.js tests were also covered by options-wrong-type.js.
The tests for add/subtract without an options argument were also covered by options-undefined.js.
ISO strings may separate the time from the date with a case-insensitive T,
or a space. This adds tests to all entry points that take ISO strings, to
ensure that they accept an uppercase T, lowercase T, or space as the time
separator.
These tests are based on the one test for Temporal.PlainDateTime.from that
was already present.
I suggested in #3517 that these lines should be removed but didn't realize
they must be present because TemporalHelpers.assertPlainDateTime is going
to check the 'era' and 'eraYear' properties.
This adds coverage for the situation where we get a different answer from
Temporal.Duration.compare depending on whether relativeTo resolves to a
PlainDate or ZonedDateTime.
See discussion in
https://github.com/tc39/test262/pull/3505#discussion_r859994610
Some of these strings wouldn't have been valid even with a valid year in
them (e.g. strings ending in +01:00[UTC]) so fix up the strings that we
test. While touching these tests, I took the opportunity to regularize
them, and add some missing ones for ISO strings that convert to Calendar
and TimeZone.
Be consistent about creating Temporal objects for use in tests with direct
constructor calls, instead of relying on string coercions. This reduces
coupling in the tests.
Everywhere an ISO string is accepted in Temporal, a seconds value of :60
should always be coerced to :59, because of how leap seconds are handled
in ISO strings.
In property bags, a 'seconds: 60' property is not subject to that rule: it
should be handled according to the overflow option if there is one.
These tests existed already for some types; regularize them and add the
ones that didn't exist yet.
Each from() method except Calendar and TimeZone should test that when you
pass an instance of that type, the return value is a clone of that
instance, and a distinct object.
These tests existed already for some types; regularize them and add the
ones that didn't exist yet.
In order to test the referenceISODay of a PlainYearMonth we add an
argument to TemporalHelpers.assertPlainYearMonth.
In Date.parse() and new Date(), representations of the year 0 as -000000
must not be accepted. In the case of Date.parse(), they should yield NaN,
and in the case of new Date(), they should yield an invalid Date object,
whose valueOf() is NaN.
These tests cover, for every API entry point where a Temporal object is
expected, what happens when a value of a different type is passed in that
can't be converted.
Most entry points can convert a string to the expected Temporal type, and
will do ToString on any non-Object argument, and throw RangeError if the
result isn't a string that's convertible to that Temporal type. ToString
will throw TypeError on a Symbol.
Most entry points also take a property bag, and will throw TypeError if
the property bag doesn't have the required properties.
We also have to test for TimeZone and Calendar what happens if the wrong
type is provided as the value of a 'timeZone' or 'calendar' property in
another property bag, up to one level of nested properties.
Adds tests for conversion of a Number whose corresponding toString() value
is a valid ISO string. For some Temporal types this is possible, with a
number like 20220418.
Especially for Temporal.Calendar, we have to take into account the case
where the number is provided as the value for the 'calendar' property in a
property bag, and the case of up to one level of nested property bag as
well.
Regularizes and expands existing tests for this case.
The test for a TimeZone created from an ISO string with multiple offsets
was missing from the Temporal.ZonedDateTime constructor, whereas it was
present for several other APIs. Add it.
We already had similar tests to these for other methods, such as
Temporal.PlainTime.prototype.equals(). since() and until() should have
these tests too.
Update assertion messages in all of the existing tests as well, as per
Ms2ger's review comment.
An object may be given in any context where a Temporal.Instant is expected
(see ToTemporalInstant). There is no conversion from a property bag to an
Instant, unlike with other Temporal types. Instead the object is converted
to a string, and if its toString() method yields a valid ISO string, the
conversion succeeds. (An object with the default Object.prototype.toString
will not.)
We should make sure that we are providing the correct arguments to these
methods even if they are supposed to throw; they should throw for the
reason we expect, and not because we provided the wrong arguments.
Note that this test currently unintentionally passes, because a
TypeError is thrown for failing to convert the undefined returned from
the getter to a BigInt. But since this test was intended to test
detaching, it's no longer valid and should still be removed.
See https://github.com/tc39/test262/pull/3465#issuecomment-1098388916
The round() and toString() methods of Temporal.Instant, PlainDateTime, and
ZonedDateTime can round up or down. However, the instance must not be
treated as "negative" even when the time is before 1 BCE (years are
negative) or before the Unix epoch (epoch nanoseconds are negative). That
is, rounding down is always towards the Big Bang, and rounding up is
always away from it. Add tests that verify this.
This takes the tests of the rounding functionality of
Temporal.PlainTime.p.toString() and adds similar tests covering the
equivalent functionality to Duration, Instant, PlainDateTime, and
ZonedDateTime: all the types that have rounding and precision controls
for how they output their subsecond values.
It also takes the opportunity to improve the existing PlainTime tests:
- fractionalseconddigits-auto.js: More descriptive variable names. Added
assertion messages.
- fractionalseconddigits-number.js: Ditto.
- rounding-cross-midnight.js: Use constructor directly to remove coupling
with from().
- roundingmode-*.js: Add additional tests for specifying the precision
using fractionalSecondDigits.
- smallestunit-fractionalseconddigits.js: Add assertion messages.
This consolidates the few existing tests for options bags in Temporal
being of the wrong type, and adds them for every entry point in Temporal
that accepts an options bag.
These are mostly identical tests, but there is a variation for methods
like round() where either an options bag or string is accepted.
Add a consistent set of invalid strings for all of the
smallestunit-invalid-string.js and largestunit-invalid-string.js tests:
- "era" and "eraYear" in singular and plural
- all of the units that are disallowed for that particular method call, in
singular and plural
- an allowed unit with \0 at the end
- an allowed unit with an "i" replaced by a dotless i
- an allowed unit but with all-caps
- an unrelated string.
Of the toString() methods that have options for printing a time with
seconds and fractional seconds, PlainTime seems to have the most
comprehensive set of tests. Bring all the others (Duration, Instant,
PlainDateTime, and ZonedDateTime) in sync with PlainTime, and edit the
PlainTime ones where necessary to include improvements from the others.
Tests:
- fractionalseconddigits-invalid-string.js: copy and expand on
PlainTime's more comprehensive set of invalid strings. Add assertion
message. Fix front matter.
- fractionalseconddigits-non-integer.js: Fix front matter.
- fractionalseconddigits-out-of-range.js: make sure infinity is tested.
Add assertion messages. Fix front matter.
- fractionalseconddigits-undefined.js: copy PlainTime's more
comprehensive test with whole minutes, whole seconds, and subseconds.
Copy PlainTime's test of an empty function object. Add more
descriptive variable names and assertion messages. Fix front matter.
- fractionalseconddigits-wrong-type.js: inline and delete TemporalHelper
used here; it was only good for this test anyway. Improve assertion
messages.
- smallestunit-valid-units.js: copy PlainTime's test with a second value
with zero seconds even. Refactor repetitive tests into a loop. Copy
the invalid unit "era" from the Instant test. Add assertion messages.
A prior version of ECMA262 described invalid mathematical operations
with infinite values [1]. Update the test metadata to reflect the
corrected specification text, and add two assertions for the obsolete
conditions.

Where possible, observable calls originating from within Temporal, that
require an options argument, should pass `undefined` as that options
argument, rather than `{}` or `Object.create(null)`.

These tests check API entry points that convert strings to
Temporal.PlainDate, with a list of various strings that are all not valid
for that context according to ISO 8601.
I'd like to add basic functionality tests for string arguments, and these
tests are testing something more specific: that a Get of the "overflow"
property on the passed-in options object is observable. Rename
accordingly.
