Testing Endpoints With ASP .NET Core Integration Tests

Boost your ASP.NET Core skills with real‑world integration tests. You’ll spin up a Minimal API, hit it with real HTTP calls, and verify routing, middleware, DI, and JSON payloads. Less mocking and better test coverage. What you’ll do - Build a .NET 8 Minimal API in VS Code - Add a strong integration‑test project with MSTest + WebApplicationFactory - Swap real services for fakes on the fly - Hit endpoints with HttpClient and assert full request/response shapes - Keep refactors painless by testing behaviour, not plumbing - I walk you through every step, line by line. You’ll finish with green tests, clean code, and total confidence that your endpoints behave in prod.
