"""Run tests on a specific repo.

This file is called by marking_puller.py

Its job is to be set up and torn down for every student so that there is no
namespace pollution. Its run as a subprocess. The args are where the tests are,
and where the repo is. In almost all cases the tests are the teacher tests, and
the repo changes for each student.
