HTTP integration tests validate server behavior by automating real request and response assertions against your API endpoints. They confirm that status codes, authentication enforcement, and middleware behavior align with your OpenAPI contracts across server changes.

The best way to test API authentication and middleware behavior is through end-to-end HTTP integration tests that assert real request validation and authentication handling. This approach verifies that middleware correctly enforces auth rules across your REST API endpoints.

You assert status codes and DB side effects in REST API integration tests by executing real HTTP requests through the repository test harness and verifying the resulting server state. This confirms that endpoint contracts and database mutations align with expected behavior.

Yes, this HTTP integration testing approach works with OpenAPI alignment guidance to validate endpoint contracts. It verifies that real HTTP request and response assertions match your defined API specifications during server behavior testing.

You need real integration tests when evolving APIs and services to guarantee middleware, authentication, and endpoint contracts remain correct. Mocked tests miss actual DB state side effects and fail to validate true server behavior across REST API changes.
