"""Run all tests in the same directory.

This suite is expected to be run under pywebsocket's src directory, i.e. the
directory containing mod_pywebsocket, test, etc.

To change loggin level, please specify --log-level option.
    python test/run_test.py --log-level debug

To pass any option to unittest module, please specify options after '--'. For
example, run this for making the test runner verbose.
    python test/run_test.py --log-level debug -- -v
