Has anyone built a great solution to 'run all my unit tests automatically'? It's straightforward to write a while loop in bash, but handling timeouts, syntax errors etc well is hard. Running on save would be good, although I wonder if you could run fast tests on each keystroke.

I've been experimenting with an 'evaluate up to cursor' mode for my PL project. I love evaluating self-contained snippets in Lisp, this generalises the idea. The interpreter remembers the arguments when you run tests, then can re-use them when you say 'eval up to here'. What do you think?
