xUnit project example for unit testing in .NET and C#

Download our xUnit project to start learning about how to unit test your .NET and C# code.

The example includes singular test methods using the Fact attribute, as well as the Theory and InlineData attributes which are used for multiple tests on the same test method.

It also includes some of the different Assert methods used, including Assert.True and Assert.Equals.

By running the tests in Visual Studio, you'll be able to debug them by putting breakpoints on methods that are used within them.


This is the software that will need to be installed onto your machine.
