Answer
Testing involves:

- Validating status codes, payloads, headers
Quick Answer
Web API testing: unit tests with xUnit/NUnit + Moq (mock services, test action logic in isolation). Integration tests with WebApplicationFactory - spins up the real app with an in-memory or test database, makes HTTP calls with HttpClient. Test all HTTP verbs, status codes, error cases. Use TestServer for lightweight integration tests without a real HTTP server.
