Teardown example (in dependency pattern)

I use the recommended dependency pattern from the doc, which is very well explained for the setup part. But I'm struggling with the teardown part, as I can't find any examples of what the gloabal.teardown.ts file should contain. I've tried to use a test function in it, mimicking the setup, but it fails with no logs at all (my setup succeeded with no logs at all either) contrary to what I understood from the docs

I'm willing to contribute to the docs to make it more clear about it, once I'll have really understand it myself 😄
