 If you use 2 factor authentication on your Github account, tests that require a login/password authentication will fail.
-You can use `python -m github.tests Issue139.testCompletion --record --auth_with_token` to use the `oauth_token` field specified in `GithubCredentials.py` when recording a unit test interaction. Note that the `password = ""` (empty string is ok) must still be present in `GithubCredentials.py` to run the tests even when the `--auth_with_token` arg is used. (Also note that if you record your test data with `--auth_with_token` then you also need to be in token authentication mode when running the test. A simple alternative it to replace `token private_token_removed` with `Basic login_and_password_removed` in all your newly generated ReplayData files.)
