One file example to run data driven tests using python and nose with XML and HTML reports

I was discussing data driven tests with a colleague and how easy it to create in python just with nose test framework.

The file looks like:

def test_dirs():
    for data in test_data():
        yield check_dir, data[0], data[1]

def check_dir(dir_ref, dir_new_gen):
    assert len(dir_ref) > 1
    assert len(dir_new_gen) > 1

def test_data():
    return [["dir1_ref", "dir1_gen"], ["dir2_ref", "dir2_gen"]]

I created a repository  and shared with him following is current content of the Readme:
