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.
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.
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.
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.
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.
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.
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/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.
These tests already existed for PlainDate. Copy them to the other types
(and use the constructor instead of from() in order to be as simple as
possible)
Some of these (in PlainDate) had already been rewritten to test more
invalid strings that are otherwise valid units. This commit takes these
improvements and brings them to all of the similar tests for other types'
since() and until() methods.
https://github.com/tc39/proposal-temporal/issues/1753 records the
consensus reached at the October 2021 TC39 meeting to disallow "-000000"
as an extended year, both in Date.parse and Temporal. This adds tests for
the Temporal part of that.
https://github.com/tc39/proposal-temporal/pull/1893 was a bug that caused
the 'offset' property to be ignored in ZonedDateTime property bags. Add
tests that ensure it is not ignored.
This was a normative change that achieved consensus at the October 2021
TC39 meeting.
This requires a few adjustments of time zone names and offsets in some
places. The only named time zone that is required to be supported by an
implementation not supporting ECMA-402 is "UTC".
In order to test this functionality on hosts that don't have Intl, we have
to use "UTC" and offset-only time zones here, as the full set of IANA time
zone names are not required to be supported across all hosts.
This makes some progress on https://github.com/tc39/test262/issues/3253
Nails down intended behavior of `PlainDate` and
`PlainDateTime`'s `since` that is already true in the
polyfill but which was specified in a buggy way (and hence
potentially not true in an implementation of Temporal).
Add similar tests for Instant, PlainTime, PlainYearMonth, and
ZonedDateTime.
Reference:
https://github.com/tc39/proposal-temporal/pull/1881
Move part of the test of toLocaleString which depends on
15 Amendments to the ECMAScript® 2021 Internationalization API Specification
to intl402. Keep behavior specified in earlier chapters in built-ins
Unfortunately, in #3304 I made a last-minute mistake when I added the
uncallable value to the assertion message, and neglected to test it;
Symbols can't be converted to strings like that, so these tests would
fail. This fixes the assertion messages.
