How to use integration test for Controller action that uses Db transactions In laravel php 8.

To write integration tests for a controller action that uses database transactions in Laravel PHP 8, follow these steps:

1. Set up your testing environment:

   • Make sure you have Laravel installed and configured correctly.
   • Ensure you have a database set up and configured in your .env file.
   • Install the Laravel testing tools by running composer install --dev phpunit mockery pest.

2. Create a test file:

   • In your tests/Feature directory, create a new file with a descriptive name, e.g., TestControllerAction.php.

3. Write the test case:

   namespace Tests\Feature;
   
   use App\Models\User;
   use Illuminate\Foundation\Testing\RefreshDatabase;
   use Tests\TestCase;
   
   class TestControllerActionTest extends TestCase
   {
       use RefreshDatabase;
   
       public function test_controller_action_uses_db_transaction()
       {
           // Arrange
           $user = User::factory()->create();
   
           // Act
           $response = $this->actingAs($user)
                             ->json('POST', '/api/actions', [
                                 'field1' => 'value1',
                                 'field2' => 'value2',
                             ]);
   
           // Assert
           $response->assertStatus(200); // or any other expected status code
           $this->assertDatabaseHas('users', [
               'email' => $user->email, // or any other column and value you want to check
           ]);
   
           // Additional assertions if needed
           // ...
       }
   }
   

   In the example above, we're using the RefreshDatabase trait to ensure a clean database state before each test. We're also using the actingAs method to authenticate the user before making the request.

4. Run the test:

   • Run the test by executing php artisan test in your terminal.

The test case above demonstrates a basic example of testing a controller action that uses database transactions. You can modify the test case to cover more complex scenarios, such as testing for errors or multiple database operations within a transaction.
