"""

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 = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'

    # run the test

    runner.run(my_test_suite)
