Optional test name if you only want to run 1 test. If not provided all tests in `testclass` will be loaded.
Arguments for the test class constructor. These will be passed after the test method name.

Attempts to read the default connection string from the setup.cfg file.
If the file does not exist or if it exists but does not contain the connection string, None is returned. If the
file exists but cannot be parsed, an exception is raised.
