Notes

This video assumes that you've already installed entr. On MacOS you can run;

brew install entr

If you're running linux then you can build this yourself. If you're running ubuntu then you might also be able to install via:

sudo apt-get update
sudo apt-get install entr

Either way, assuming you've got entr installed you can now automatically run the unit tests apon saving by running:

ls checking/*.py | entr pytest test.py::test_starts_correctly
