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".
Includes key should use flow notation to be able parsed easier
as suggested in https://github.com/tc39/test262/issues/1997
Added this check to the linting script and updated tests accordingly.
Prior to this patch, the tests for certain Array prototype methods
incorrectly expected all elements to be "visited" even when a given
property was not present according to HasProperty.
Update the tests to reflect the fact that under such conditions, the
removed element is not visited.
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
Tests for the normative changes made to Temporal in
https://github.com/tc39/proposal-temporal/pull/1873
This adds a new Temporal helper calendar that asserts that its dateAdd()
method is always called with a PlainDate instance. This allows testing
that relativeTo parameters are always converted to PlainDate if they are
not ZonedDateTime and not undefined. Prior to the normative PR, they
would be converted to PlainDateTime instead.
Additionally and optionally, the helper calendar can also assert that its
dateAdd() method is called with a specific PlainDate instance. This allows
testing that the instance is the same PlainDate passed as the relativeTo
parameter (in the case of Duration methods) or is the receiver (in the
case of PlainDate methods). For the PlainDateTime and PlainYearMonth
methods the PlainDate instance is synthesized internally so there is no
need to assert that dateAdd() is called with a specific instance.
A number of tests were found to be duplicative based on an analysis of
file contents (included below). Eliminate the duplication by removing
the version of each test with less precise metadata. In cases where this
removal could technically be considered a reduction in coverage,
preserve the verification of additional semantics in the remaining test.
