There are some add-ons for DUnit, maybe this is worth a new entry on SO. Two which I can put on the list now are
- FastMM4 integration: Unit tests will automatically detect memory leaks (and other things), works with DUnit 9.3 and newer
- OpenCTF is a 'component test
framework' based on DUnit, it
creates the tests dynamically for
all components in the project's
forms, frames and datamodules, and
tests them using customized rules (open source)
