Thanks!

[asottile]

nice! how did you find these?

[asottile]

context ;)

Don't remember in particular, but usually it's some homegrown greps, https://github.com/client9/misspell etc

[RonnyPfannschmidt]

@asottile that one looks like an nice potential addition as a pre-commit hook ^^

Weird, can anyone explain why codecov is saying that the coverage has decreased, when clearly that's not the case? 🤔

[blueyed]

why codecov is saying that the coverage has decreased, when clearly that's not the case?

I think codecov is still buggy / having problems with the pytest repo in general.
But here it might be a general bug/issue, maybe because of touching doc strings only, which might be considered as not being covered and then it gets it wrong etc, but really do not know.

Sometimes it also confuses the base commit - i.e. Travis gets run on the merge commit, but then it is compared to master or something like that.
