FPTest (Free Pascal Testing Framework) is a unit testing framework. It is a fork of the DUnit2 project created by the late Peter McNabb, but tweaked specifically for use with the Free Pascal Compiler.
How does it compare to FPCUnit?
I (Graeme Geldenhuys) was a long time user of FPCUnit. I even contributed and helped extend the FPCUnit project. But FPCUnit has some design flaws which makes it mostly useful for smaller project and less complicated test suites. The FPTest testing framework overcomes all the issues I had with FPCUnit, and adds many more features.
