Writing tornado.testing.test as simple python script (and pass command line options to the testee).
I wanted to execute tornado.testing unit test with command line options(tornado.options). Something like python3 -m tornado.test.runtests test.py --port=8080 However I found this is impossible, because runtests tries to process options by itself. Then I tried to do this python3 test.py --port=8080 by putting following code at the end of the test script(test.py in this case). if __name__ == "__main__": tornado.testing.main() * tornado.options.parse_command_line() is called at the top of the testee's program. This didn't work because of "AttributeError: 'module' object has no attribute 'all'" error. So, I avoided this problem by adding "all()" function to the test.py like this, and it finally works. def all(): import unittest return unittest.defaultTestLoader.loadTestsFromNames([__name__])
