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.

Using xUnit for Test-Driven Development in .NET

* **The fundamentals of automated testing:** We learned that automated tests consist of code that’s written to test the application code, which significantly improves quality-control efforts.

* **Fundamentals of xUnit:** We learned that xUnit is one of the main testing frameworks on .NET, along with NUint and MSTest.

* **Parametrized and nonparametrized tests:** We covered the use of the `Fact` and `Theory` attributes in the test methods, which allow us to run tests with and without parameters, respectively.

* **The principles of TDD:** We covered the three principles of TDD— red (failing the test), green (passing the test), and refactor (making the code clean).
