| /datum/unit_test/focus_only | These tests perform no behavior of their own, and have their tests offloaded onto other procs.
This is useful in cases like in build_appearance_list where we want to know if any fail,
but is not useful to right a test for.
This file exists so that you can change any of these to TEST_FOCUS and only check for that test.
For example, change /datum/unit_test/focus_only/invalid_overlays to TEST_FOCUS(/datum/unit_test/focus_only/invalid_overlays),
and you will only test the check for invalid overlays in appearance building. |
