Testing broken?

Silverstripe Version:

4.7.3

Question:

I’m trying to use fixture files and substitute objects and am just running into a wall of errors. So I made a very basic installation of silverstripe/recipe-cms and tried to run the tests in vendor/silverstripe/versioned-admin/tests and got a wall of “Incorrect tablename” errors. I’m trying to decide whether it’s worthwhile using the testing facilities in a real project. I’ve set up $extra_dataobjects but that doesn’t help. Am I missing something simple, or is testing just broken now? I suspect the latter, since versioned-admin is a supported module.
