Actually most if not all the tests in this generated test class don’t look that good:

Ideally the tests should be reviewed but since this is painful I think we should just add them and when we fix the bug, the generated tests will fail and we’ll just need to regenerate them. This means the global coverage and mutation score could actually decrease as a result.
