Can I make tox fail when there are TODOs in the code?

Question

Currently, I run

grep -rnI "TODO" foodir

and tox to check if I can commit. Is there a way to make tox fail if the grep returns something?

Answer 1

exit 1 should be enough. Something like this in tox.ini:

[testenv]
commands =
    grep -FInrq TODO . && exit 1 || exit 0
