Using xUnit for Test-Driven Development in .NET

Test-driven development (TDD) is a proven way of developing high-quality applications with clean and well-maintainable code. In this course, you will learn how to use the xUnit testing library to apply the principles of test-driven development on .NET.

You will start this course by reviewing the fundamentals of xUnit and how automated testing works on .NET. Then, you will practice the key TDD fundamentals. After this, you will move to more advanced topics, such as mocking, understanding the testing pyramid, running integration tests against hosted apps, etc.

By the end of the course, you will have learned how to develop high-quality software by following the TDD principles. You will also have learned how to use xUnit to write any automated tests supported by .NET.
