NUnit documentation
+NUnit is the open-source unit-testing framework for .NET. Write a test in a few lines, get warnings about mistakes as you type from the NUnit Analyzers, run it with many sets of data, and run it anywhere: in Visual Studio, Rider, VS Code, on the command line or in your build pipeline.
