Some of us still "live" in a programming environment where unit testing has not yet been embraced. To get started, the obvious first step would be to try to implement a decent framework for unit testing, and I guess xUnit is the "standard".
So what is a good starting point for implementing xUnit in a new programming language?
BTW, since people are asking: My target environment is Visual Dataflex.
I found Pragmatic Unit Testing in C# with NUnit very helpful!
