These tests cover the normative change approved in the July 2025 TC39 plenary. See https://github.com/tc39/proposal-temporal/pull/3130. All properties of user-passed options objects should be read and cast before any "algorithmic validation" is done. This is a lot of tests, that cover every entry point where an options object is passed in, where subsequently an exception can be thrown or user code can be called. However, the normative change only affects 10 of these tests: - Instant.p.since,until,toString - PlainDate.p.since,until - PlainTime.p.since,until - PlainYearMonth.p.since,until - ZonedDateTime.p.toString The other 35 tests simply close a gap in coverage.
