Rollback database after each test method

Hey,

I've got bunch of tests that used to run on Sqlite in memory database and it all works fine. Now that I need to run it against an actual MySQL database, errors keep on coming. I need database to be fresh (no data in it) each time a test function runs (not a test class, but each test method).

I've been using RefreshDatabase trait which does the trick. Or doesn't. I have no idea. When I run test methods individually, they all work fine. But when I run them in bulk (either entire class or the entire suite), it's all filled with errors because the data is already filled in the database. So if I seed the database in one test method, then I need the same seeder in another test method, it would try to seed twice, hence the failures. RefreshDatabase class has a refreshTestDatabase method which, in theory, should rollback everything after each tearDown (each time a test method finishes). And debugging shows that it actually runs. However, database is still not clean, it still has data in it.

Environment is simple: phpunit.xml says DB_CONNECTION is mysql. Each test that needs a database uses RefreshDatabase trait. That's it. Running Laravel 5.8.

I've been really struggling to run PHPUnit tests on MySQL. Anyone know a good way to do that? Ya need any more info?
