This is a simple project that we can play with to understand some "coverage" tools in Python. It is essentially the "TicTacToe" program from a few months ago (it's okay if you didn't come to those meetups).
Create a virtualenv and install the example:
virtualenv venv ./venv/bin/pip install --editable . source ./venv/bin/activate
On Windows, instead of the last line use this:
./venv/bin/activate.bat
Once you're set up like the above (in a shell where you've run the "activate" part) you can run the tests:
py.test -sv tests
