Here are some of the standard tests for property metadata of the
Array.fromAsync property and for the built-in function object. These don't
require doing anything asynchronously, so can be considered separately
from the Async Helpers RFC.
* Reject exceptional input to `isConstructor`
Prior to this commit, the `isConstructor` harness function would return
`false` when invoked with a value that lacked a [[Call]] internal
method. While it's true that such values are not constructors, there are
no tests which benefit from using `isConstructor` to make such an
assertion.
Extend `isConstructor` to throw an error when invoked with a
non-function object. Update a test which was misleadingly invoking the
function with the value `undefined`.
* fixup! Reject exceptional input to `isConstructor`
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.
1. String.prototype.toWellFormed's name is "toWellFormed".
2. "asserts" does not exist in the test harness, and "assert.throws"
expects the error type first.
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.
While we're at it, use assert() instead of assert.sameValue() for brevity,
if we are not specifically testing that the return value of hasOwnProperty
is the value true or false; and add more informative assertion messages to
help with debugging.
In some cases, the Object.hasOwnProperty.call could be replaced with
verifyProperty(), if the property descriptor was also being verified at
the same time.
This fixes some tests that were faulty to begin with: a common mistake was
Object.hasOwnProperty(obj, prop) which is probably going to return false
when that's not what you want.
The only instances left of `Object.hasOwnProperty` are one regression test
in implementation-contributed which I can't tell if it was intentionally
needed to trigger the regression, and a few instances of
`Object.hasOwnProperty('prototype')` which would defeat the purpose to
convert into `Object.prototype.hasOwnProperty.call(Object, 'prototype')`
form.
Closes: #3524
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.
Temporal issue: https://github.com/tc39/proposal-temporal/issues/2405
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.
%TypedArray%.prototype.map's iteration count does not change even though the source view is resized during the iteration.
And since result is just returning index, then result array should be [0, 1, 2].
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.
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.

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
rounding modes and standardize them. Add tests for Instant and
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.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2287 which reached
consensus at the July 2022 TC39 meeting.
It adds tests that ensure that PlainTime strings which require a T
designator for disambiguation, are not disambiguated by adding a calendar
annotation.
This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2284 which reached
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.

Values given as the fractionalSecondDigits option are now truncated to

A normative change that reached consensus at the June 2022 TC39 meeting

in PlainDate.from() and PlainDateTime.from(), in the case of a fast-path
conversion.
See https://github.com/tc39/proposal-temporal/pull/2225
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.
This adds tests for a normative change which reached consensus in the June
2022 TC39 meeting, ensuring that the representable range of
Temporal.Instant is always the same regardless of which time zone offset
is used when converting from a string.
