From Zero to Hero: Effective testing in C#

Testing is an absolute must when building reliable software. It allows us to make code changes with minimal amount of risk and it ensures that bugs or problems within our codebase are caught early, before they can even have any customer impact. It can also let us know how our application performs under pressure and we can use that information to optimize what really matters.

This workshop will get you started on the right track and teach you all the best practices you need to know to write clean and effective unit and integration tests in .NET with C#.
