From Zero to Hero: Integration testing in ASP.NET Core
Learn integration testing in ASP.NET Core with real-world examples. Ensure your services are reliable and behave as expected using modern techniques.
About This Course
Integration testing has quickly become one of the most used and most
important types of testing for modern .NET and ASP.NET Core applications.
This is mainly due to how much value a single Integration test can add and
how easy it has become nowadays to write Integration Tests due to advancements
in tooling. In this course, Nick Chapsas will introduce you to the beautiful
world of modern integration testing and how you can ensure that your services
behave as expected.
