From Zero to Hero: Unit testing for C# Developers
Learn modern unit testing in C# from scratch! This course by Nick Chapsas teaches you how to write reliable, maintainable unit tests, covering key concepts, techniques, and real-world applications.
About This Course
There is a reason why Unit Testing is the bottom layer in the testing pyramid.
You can only build a solid testing suite on a robust foundation. Nothing is more reassuring when
working on a codebase than knowing that if you accidentally break something, a test will alert you,
saving you hundreds to thousands or even hundreds of thousands of dollars in potential customer impact.
In this course, Nick will teach you how to write modern unit tests for your code bases so you are always
confident in change. Oh, and if you don't know what the testing pyramid is, don't worry.
You will after you take this course.
