Mongo executable for pytest-mongo

Hi,

I’m running pytest which needs access to /usr/bin/mongod. What path is the mongo executable accessible on if I add it with the docker image command? Is it at all? Or do I need to install it separately?

On a sidenote, I am runnig pytest via python setup.py pytest which does not take advantage of the dependencies cache. Is there any way to speed up the test, by caching the eggs as it does on my local machine?

Thanks!
