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.

https://github.com/tc39/proposal-temporal/pull/2003 is a normative change
that reached consensus at the March 2022 TC39 plenary meeting. This adds
tests that verify the new spec text is implemented correctly, performing
arithmetic on a PlainYearMonth instance that would previously have thrown
an error if it was implemented as written.
https://github.com/tc39/proposal-temporal/pull/2090 is a normative change
that reached consensus at the March 2022 TC39 plenary meeting. This adds
tests that verify the change made to the formatting of years between 0 and
999 inclusive in all toString and toJSON methods of Temporal types that
can output an ISO year number in their return value.
(Philip, March 2022: This was originally Frank's PR #3057. I did some
reformatting, removed duplicate tests, addressed the review comments that
I left the first time around, and added some cases that I felt were not
yet complete.)
(Philip, March 2022: This was originally Frank's PR #3060. I did some
reformatting, removed a test that didn't exercise the whole feature, and
combined some duplicate tests with some existing tests.)
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)`.
See tc39/proposal-temporal#1685.
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.
* Create a Temporal.PlainDateTime with all arguments supplied.
Migrates some tests that currently exist in the
proposal-temporal repo.
* Check all data in Temporal.PlainDateTimes, variously constructed
Enrich existing tests to check all basic data in the
instance of `Temporal.PlainDateTime`, not just a single
field.
These additional checks were motivated by the migration of
existing Demitasse tests in the proposal-temporal repo to
test262. The Demitasse tests check more than a single
field.
Here's a test I should have included in #3395. It's allowed to replace the
"T" in the middle of an ISO string with a space, but not when the "T" is a
time designator prefix. This assertion ensures that implementations make
this distinction correctly.
https://github.com/tc39/proposal-temporal/issues/1910 found a bug in an
indentation level of a line in the Temporal proposal, which affected the
outcome of the PreparePartialTemporalFields abstract operation. This adds
tests for all entry points that use that abstract operation, to make sure
the behaviour is correct: only defined properties are copied in with()
methods.
This was a normative change that achieved consensus at the December 2021
TC39 meeting.
https://github.com/tc39/proposal-temporal/pull/1956 clarified that the
fractionalSecondDigits and smallestUnit options to
Temporal.Duration.p.toString() specified the exact number of digits after
the decimal point, no more and no less.
This was a normative change that achieved consensus at the December 2021
TC39 meeting.
https://github.com/tc39/proposal-temporal/pull/1952 added support for time
designator prefixes in PlainTime strings. This adds three tests to all
entry points that convert an ISO string to a PlainTime:
- no-implicit-midnight: ISO strings with only a date and no time are no
longer accepted. Previously they were implicitly interpreted as 00:00.
- with-time-designator: Tests that various forms of string with time
designator are correctly parsed.
- time-designator-required-for-disambiguation: Tests various cases where
a string without a time designator is ambiguous and therefore the time
designator is required, as well as various cases that implementations
might assume are ambiguous but in fact are not.
This was a normative change that achieved consensus at the December 2021
TC39 meeting.
https://github.com/tc39/proposal-temporal/pull/1907 was a bug that caused
negative Duration strings with fractional units to be rounded incorrectly.
Add tests that ensure the rounding mode is correct.
This was a normative change that achieved consensus at the December 2021
TC39 meeting.
A follow up to the previous commit, this rewrites some tests that relied
on the lack of brand checks for certain Temporal.TimeZone methods.
https://github.com/tc39/proposal-temporal/pull/1693 added brand checks to
these methods.
We can no longer use a plain object time zone or even a Proxy with a real
branded Temporal.TimeZone object as its handler to do these tests, so we
instead create an instance of Temporal.TimeZone and define own accessor
properties on it in order to test the observable property accesses that we
need to see according to the spec text.
This requires an improvement to TemporalHelpers.observeProperty() in order
to be able to log property accesses to Symbol-valued properties.
https://github.com/tc39/proposal-temporal/pull/1693 added checks for the
receiver of certain Temporal.Calendar and Temporal.TimeZone methods. Add
branding tests for these methods, similar to the already existing branding
tests.
This was a normative change that achieved consensus at the December 2021
TC39 meeting.
