xUnit is an open source modern testing framework for .NET written by the author of NUnit v2, a unit-testing framework for all .NET languages. xUnit is the first testing framework that is compatible with .NET Core.

xUnit is the default testing tool in Visual Studio for .NET Core and is currently being used by Microsoft themselves in their modern projects.

Let's check out the features of xUnit, as follows:

• Supports multiple platforms: You can use it for testing .NET Framework applications, Xamarin applications, .NET Core applications, and ASP.NET Core applications.
• Supports parallel test execution: It speeds up the execution of unit tests.
• Supports data-driven tests: You can write one test and then pass different data inputs to see different expected outputs.
• It is designed to be extensible: You can add more data types, attributes, and asserts, and also use xUnit alongside other testing frameworks.
