Do you want to test all of your Entity Framework queries without setting up a test database? Do you want to test your API without leaving Visual Studio? Do you want to add integration tests to your CI build without adding another library? Do you want to "cheat" and hit 95%+ code coverage? In this talk, I will walk through using the WebApplicationFactory (Microsoft.AspNetCore.Mvc.Testing) library to spin up your API in memory. I will then show how to add an in-memory data connection. Finally, I will pull it all together and show a full integration test.
