But the test database itself has a location in file system. Why don't make it 
available to tests? Finding it using "id" and current working directory is a 
little bit elaborated.

Thanks for this information.

What do you think about sys.path for python.ExecTest? Isn't expecting 
dir_path/QMTest there a reasonable expectation? I've actually wrote a test 
class that can add it there, but the need to extend QMTest for this simple 
task somewhat bothers me.
