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'm experimenting with live-evaluating tests in my programming language project. It's relatively fiddly to hook up a UI for this, but it saves a precious keystroke to run the tests! I'm hoping that it results in more, better tests due to the convenience.

I'm designing a programming language and trying to decide the type of `let x = 1;`. Should it be Unit or Int? Advantage of Int: really convenient when evaluating snippets in a REPL. Advantage of Unit: It's much less confusing when type inference runs on an incomplete function.
