I’ve released a new version of seatest which fixes some little bugs / flaws and also introduces global setup / teardowns.
It can be found at http://code.google.com/p/seatest/
I’ve found it really useful for the C based projects I’m working on. The only thing I think might be useful is some tools to help generate new tests / test fixtures / suites. In Visual studio I have both Visual Assist and Resharper which provide templating capabilities. But it might be nice to build my own custom tools specifically for seatest.
Most of my projects are for embedded systems but I tend to cross compile. So I develop everything in visual studio and stub out the hardware layer. Unit test the heck out of it, then compile for the target device. Tends to be a very quick way to develop.
