Python 2.7, please. You will also need Chrome installed and .chromedriver file added to $PATH environment variable as I use Chrome in tests. If occasionally you have Windows installed, unfortunately I have no idea how to run my tests there :)
Clone the repo. Then create and activate virtualenv and install dependencies:
virtualenv env
source env/bin/activate
pip install -r requirements.txt
Run tests:
pytest tests.py
If you want to run tests in parallel mode (e.g. in 2 threads):
pytest -n 2 tests.py
Tests have incorrect credentials (of course they do, it's a public repo). If you are really up to running them, please change login and password variables to valid ones in tests.py::TestTest::test_login_positive.
