Docker + pycharm + teamcity

I am new to PyCharm and have an existing django project that uses a docker-compose configuration. When I start my django runserver I get some logging about teamcity:

backend_1 | ##teamcity[enteredTheMatrix]
backend_1 | Creating test database for alias 'default'...

which then runs the tests. On test failure the runserver doesn't start.

1) I don't understand why this is happening
2) how can i switch the teamcity off
