Closing in favor of godotengine/godot-proposals#432, since this is more of a missing feature/documentation than a bug.

[evan-boissonnot]

Ok, taht's right : if the next feature will drop this bug, I'm ok :)

[evan-boissonnot]

Hug I retry unit tests, and really I'm not ok, it's not a missing doc, it's really a bug for me.
Why am I not able to create a unit test as usual ?

Hey @evan-boissonnot, you may write me on discord van800#9412. I can explain you the difficulty with UnitTesting support.
