[Bug]: A dependency with the name `Pest\Mutate\Contracts\MutationTestRunner` cannot be resolved.

[TobiasNagel01]

What Happened

In my Bitbucket Pipeline, I can't run my tests:

I am just running php artisan test without --mutate, but all my files have the covers(...) method to ensure that I can run the mutate tests.

Locally on my sail enviroment, both with and without --mutate works flawlessly.

The Pipeline Image running has PCOV installed and configured.

php artisan test
Pest\Exceptions\ShouldNotHappen
