"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    import unittest
    import HTMLTestRunner

    ... define your tests ...

    if __name__ == ‘__main__‘:
        HTMLTestRunner.main()


For more customization options, instantiates a HTMLTestRunner object.
HTMLTestRunner is a counterpart to unittest‘s TextTestRunner. E.g.

    # output to a file
    fp = file(‘my_report.html‘, ‘wb‘)
    runner = HTMLTestRunner.HTMLTestRunner(
                stream=fp,
                title=‘My unit test‘,
                description=‘This demonstrates the report output by HTMLTestRunner.‘
                )

    # Use an external stylesheet.
    # See the Template_mixin class for more customizable options
    runner.STYLESHEET_TMPL = ‘‘

    # run the test
    runner.run(my_test_suite)
