usually it’s called “context” not “tags” because it is basically current test metadata that can be set either by testing framework/lib or you, manually, specifying tag.

The argument to setup is the “test context” which contains all metadata for the currently running test [1]. Tests can be tagged and those tags will live in the context [2].
