 There are some tags that are only allowed within some contexts and not globally. More precisely:

 - `@group`, for easier collecting unit tests together, following the guidelines in the [PHPUnit MoodleDocs](../../tools/phpunit.md#using-the-group-annotation).
 - `@requires`, to specify unit test requirements and skip if not fulfilled. See [`@requires` usages](https://docs.phpunit.de/en/9.6/incomplete-and-skipped-tests.html#incomplete-and-skipped-tests-requires-tables-api) for more information.
