Filament tests failing with testbench 9.x

[mokhosh]

• Testbench Version: 9.x-dev c1a5b1f
• Laravel Version: dev-master 39561b1
• PHP Version: 8.3.3
• Database Driver & Version: sqlite :memory:

Description:

We've been working on dependencies supporting Laravel 11 to be able to support it in Filament. https://github.com/filamentphp/filament/pull/10972

Now the dependencies are ok, but most tests fail with this error:

  FAILED  Tests\src\Actions\ActionTest > it can call an action with data                                  PDOException
  There is already an active transaction

I checked out the PRs and commits of laravel/framework, but none of them seemed to have caused the issue. I'm guessing it's a testbench issue, specially after going through this PR https://github.com/laravel/framework/pull/49385

Can you please shed some light?

Steps To Reproduce:

• git clone git@github.com:filamentphp/filament.git && cd filament
• git checkout laravel-11
• composer install
• composer test

https://github.com/laravel/framework/pull/49385 is not merged yet and has nothing to do with this issue.

See https://github.com/laravel/framework/pull/47912

In Laravel 11, RefreshDatabase and LazilyRefreshDatabase combined with in-memory database will keep PDO instances between tests and is the root cause of this issue. You would need to reset RefreshDatabaseState between tests.
