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.
A normative change that reached consensus at the June 2022 TC39 meeting
was this small change to throw on an invalid value for the overflow option
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 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.
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.
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.
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.
