Testing PHP: Database Integration Tests

Want to make sure your Laravel app is really saving data correctly? In this video, we write feature tests that interact directly with the database — using Pest and Laravel’s built-in testing tools.

We’ll walk through:

Using RefreshDatabase to reset your DB before each test
Testing invalid form submissions and asserting no data is saved
Verifying validation errors are stored in the session
Writing happy-path tests for successful subscriptions
Using assertDatabaseHas() and assertDatabaseEmpty() like a pro

This lesson is perfect if you’re ready to go beyond controller testing and start verifying that your Laravel app works from request to database - just like in the real world.
