"""A TestRunner for use with the Python unit testing framework. Itgenerates 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 unittestimport 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 filefp = 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 optionsrunner.STYLESHEET_TMPL = '<link rel="stylesheet" href="my_stylesheet.css" type="text/css">'# run the testrunner.run(my_test_suite)------------------------------------------------------------------------Copyright (c) -, Wai Yip TungAll rights reserved.Redistribution and use in source and binary forms, with or withoutmodification, are permitted provided that the following conditions aremet:* Redistributions of source code must retain the above copyright notice,this list of conditions and the following disclaimer.* Redistributions in binary form must reproduce the above copyrightnotice, this list of conditions and the following disclaimer in thedocumentation and/or other materials provided with the distribution.* Neither the name Wai Yip Tung nor the names of its contributors may beused to endorse or promote products derived from this software withoutspecific prior written permission.THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "ASIS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITEDTO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR APARTICULAR PURPOSE ARE DISCLAIMED.
