NUnit is a popular open source alternative to the Microsoft MSTest framework and has over 1.5 Million NuGet downloads. NUnit can be used to write a variety of tests, from unit and integration tests, through to automated UI tests (when used in conjunction with other frameworks). In this course you'll learn about the general qualities of good tests before learning how to write and run tests in Visual Studio, from the command line, and using the NUnit GUI tool. In module 2 you will learn how to assert that your tests should pass or fail, including how to assert against floating point values, collections, and how to check that exceptions are thrown when expected. In the final module you will learn some additional attributes to perform tasks such as creating data-driven tests.
