Optimise for unnecessary DB migrations

Here is an example that ensures that you are still able to write tests that do not depend on the database - not running db migrations.

namespace Tests;

use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
use Illuminate\Support\Facades\Schema;
use Laravel\Passport\ClientRepository;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;

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

        if (Schema::hasTable('oauth_clients')) {
            resolve(ClientRepository::class)->createPersonalAccessClient(
                null, config('app.name') . ' Personal Access Client', config('app.url')
            );
        }
    }
}

Then in your test:

...

use RefreshDatabase;

/**
 * Test login
 *
 * @return void
 */
public function test_login()
{
    $this->withExceptionHandling();
    $user = factory(User::class)->create([
        'password' => 'secret'
    ]);

    $response = $this->json('POST', route('api.auth.login'), [
        'email' => $user->email,
        'password' => 'secret',
    ]);

    $response->assertStatus(200);
    $response->assertJsonStructure([ 
       //...
    ]);
}

...

This way you are able to write tests that do not have any db migrations
