The Travis version of `pytest` seems to have been upgraded from `4.0.2` to `4.1.0` three days ago. Since then, all our test have been failing.

I was able to repro locally by installing `pytest==4.1.0` and `pytest-cov==2.6.0` which corresponds to the versions installed on Travis.

Updating to `pytest-cov=2.6.1` fixes my build locally again, though.

Could you consider also upgrading `pytest-cov` in Travis to fix things for us?

For what it’s worth, a temporary workaround was implemented in our repo, but this might still be affecting others too.

Your requirements.txt had a weak requirement (`pytest>=3.4.1`), and when a new release came out and you ran `pip3 install -r requirements.txt --upgrade`, `pip3` happily [downloaded and used version 4.1.0](https://travis-ci.org/Charcoal-SE/SmokeDetector/builds/476006742#L2152-L2154) instead. In the last passing build, you see that [it uses 4.0.2](https://travis-ci.org/Charcoal-SE/SmokeDetector/builds/475951754#L2152) from the cache.
