Removed tests have been checking the type of error thrown. Considering the whole unification issue from the user perspective, it makes more sense to me to check whether interaction with the user is properly structured, and not whether the proper exception type has been thrown. That is why I decided to use main in test_common tests and check for particular error messages in caplog.

Sorry for a post-merge review, but we are going away from these obvious messages and deleting them everywhere. Are you sure we need it here?

not necessarily, I added it only to make it consistent with metrics - I guess we could remove it in both places. How about that?

Since this is really an exception that you are testing, it would be better to test it without going through CLI, as we did before. Just a bit cleaner. Same with tests above.
