No module named 'pytest'

I think this is a user error, because I've had Ward working before, but for some reason, it's now complaining about pytest not being found. Does Ward expect the user to have this installed on their system or am I doing something incorrect here?

When you run ward it has to find tests, so it recursively searches directories for Python files. Since your virtual env is in the same directory, it looks in there and finds a lots of Python files and loads them to find tests.

If you explicitly pass the path to ward with ward --path path/to/src then it should avoid this issue. I suspect renaming your virtualenv folder to .venv might also work - I think ward specifically ignores that folder name as it's a common convention (could be wrong on that though).

Awesome. --path . here worked, but I might rename the virtual environment as well. Appreciate the help here.
