PHPUnit Testing - RefreshDatabase has different behavior when using :memory:

[indykoning]

The RefreshDatabase behaves differently when using databases other than :memory:
When an in memory database is used it will be cleared out before every function that is ran in a test file.
However if a database other than :memory: is used it's behavior changes to only clearing out the database before executing a file.

I have a seeder running on setUp() this works perfectly with the :memory: database, however it completely breaks when using any other database since old data has not been removed.
This could also breaks tests since they are build to be ran in a new database instead of one that has already been changed by previous tests.

What is the reason behind the different behavior, and is there a good way to make the tests behave the same way as :memory: databases in other databases?

could you post your setUp() method?

[indykoning]

Of course, it is quite a simple one:

protected function setUp(): void
{
    parent::setUp();

    $this->seed('DatabaseSeeder');
}
