Installing TUnit

First create an empty .NET console application:

dotnet new console --name YourTestProjectNameHere

To that project add the TUnit package:

cd YourTestProjectNameHere
dotnet add package TUnit --prerelease

And then remove any automatically generated Program.cs or main method, as this'll be taken care of by the TUnit package.

That's it. We're ready to write our first test.

.NET 8 and up

As TUnit is a newer framework, it has been built with next-generation .NET applications in mind. So it will support .NET 8 and later. This allows the framework to utilise newer language and framework capabilities, and not have to deal with legacy code.
