laravel-testing

Arrange-Act-Assert in Laravel testing separates state setup, action execution, and assertion verification. Using Pest, this pattern structures feature and action tests sequentially to ensure domain logic is validated in clear, isolated steps.

Testing isolated domain logic in Laravel uses action testing patterns to bypass HTTP requests. By mocking dependencies and utilizing factories, you validate specific domain rules directly, ensuring robust unit-level coverage without booting the full framework.

Feature testing in Laravel with Pest validates complete request and response cycles for HTTP endpoints. It leverages testing patterns to simulate HTTP requests, interact with the database, and assert outcomes, ensuring your application's endpoints function correctly.

Yes, Pest operates as a testing framework built on top of PHPUnit. To execute Laravel testing patterns with Pest, both Pest and PHPUnit dependencies must be present in your PHP environment to support the underlying testing mechanisms.

Mocking improves Laravel test maintainability by isolating the system under test from external dependencies. By simulating object behaviors, mocking ensures tests run faster and remain robust against external changes, adhering to best practices for reliable testing.

Use factories for realistic database state setup and mocking for isolating external services. In Laravel testing, factories generate database records for feature tests, while mocking prevents actual service calls, balancing integration depth with isolation.
