How to test database transactions in delete API testing in Laravel?

To test database transactions in delete API testing in Laravel, you can follow these steps:

1. Set up your testing environment by creating a new test case class that extends the TestCase class in Laravel.
2. Within the test case class, create a test method that will test the delete API endpoint. This method should make a DELETE request to the API endpoint that you want to test.
3. Inside the test method, wrap the DELETE request in a database transaction using the $this->beginDatabaseTransaction() method. This will begin a transaction and roll back any changes made to the database during the test.
4. Perform any additional setup, such as creating mock data or setting up authentication for the DELETE request.
5. Make the DELETE request to the API endpoint using Laravel's Testing HTTP client.
6. Assert that the response from the API is successful and that the data has been deleted from the database.
7. Finally, call $this->rollbackDatabase() to roll back the database changes made during the test.

By following these steps, you can test database transactions in delete API testing in Laravel to ensure that the API endpoint functions correctly and that any changes made to the database are rolled back after the test.
