"""Script to run tests with pre-configured command line arguments.

NOTICE: This test is designed to be run from the build output folder! It is
copied automatically during build.

With this script, it's easier for anyone to enable/disable or extend a test that
runs on the buildbots. It is also easier for developers to run the tests in the
same way as they run on the bots.
