When I use nose from terminal to display test result with coverage I get error and missing lines that are actually covered

$ python -m nose.core test_utils.py -s --with-coverage

saying

alright while troubleshooting I got my answer,

the test module have to have

if __name__ == '__main__': unittest.main()

in order for python -m nose.core test_utils.TestUtils --with-coverage to work

earlier i just had unittest.main()
