test_runner: support describe / it only shorthands #46562
Description
What is the problem this feature will solve?
A common shorthand when writing tests is to be able to quickly run isolated blocks of tests using describe.only and it.only.
Examples
- https://jestjs.io/docs/api#describeonlyname-fn
- https://jestjs.io/docs/api#testonlyname-fn-timeout (alias to
it.only) - https://vitest.dev/api/#describe-only
- https://vitest.dev/api/#test-only (alias to
it.only)
Currently the test runner doesn't support these shorthands.
TypeError: describe.only is not a functionerror: 'it.only is not a function'
What is the feature you are proposing to solve the problem?
Use a consistent approach with the other describe/it shorthands (skip and todo) and add another for only.
What alternatives have you considered?
