Validate software features end-to-end without mocks by executing test scripts against live services and real dependencies, directly interacting with databases and APIs to capture real-world behavior and ensure empirical accuracy.

Integration testing against live services is executed by running scenario testing scripts that interact directly with real system components, verifying actual interactions between services to ensure software behaves as expected in real-world scenarios.

You can prove API contracts by creating proof programs that execute against live application stacks, demonstrating complex behaviors using real systems rather than mocked interactions to validate the entire workflow.

To start scenario testing a user registration flow, create a new test script in the .scratch/ directory to validate the workflow from frontend submission to database persistence and email confirmation against a staging environment.

End-to-end validation does not require a specific testing framework, as it facilitates testing by executing custom scripts against live services and real system components without relying on mocks or external dependencies.

You should avoid mocks and test with real dependencies when you need empirical accuracy and want to capture real-world behavior, ensuring that complex workflows like database persistence and API interactions work correctly.
