pytest-watch is a fine quick “continuously run my tests” thing for Python in a tty. It’s nothing fancy, and the default UI is not perfect. But with -c and –no-beep and using –runner to run a custom command for your tests, it’s fine. Nice to not have to switch from my editor window to a console just to run the tests.
I’m envious of the NodeJS folks and their hipster test runners, they are very nice. Alternately I wish there were a good way to turn SublimeText into a bit more of an IDE with debugging and test output parsing. But after years of trying IDEs and going back to plain text editors, I think I’m not going to try to board that ship again.
