xUnit.net 2 is a modern, extensible, multi-platform testing framework for .NET. Currently being used by the Microsoft ASP.Net 5 development team, xUnit.net allows the creation, execution, and customization of automated tests such as unit, integration, and, when combined with other libraries, even automated UI tests. In this course, you'll learn about the features of xUnit.net 2 and learn how to write and run tests in Visual Studio Test Explorer, ReSharper, and from the command line. You'll learn to write test asserts against different types of objects, including how to assert against floating point values, collections, and how to check that exceptions are thrown when expected. The course also covers how to customize the test execution life cycle and how data driven tests can reduce the amount of test code that needs to be written and help reduce test maintenance costs.
