支持生成饼图的Python3.0的HTMLTestRunner

"""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 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)------------------------------------------------------------------------Copyright (c) 2004-2007, 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 copyright  notice, this list of conditions and the following disclaimer in the  documentation and/or other materials provided with the distribution.* Neither the name Wai Yip Tung nor the names of its contributors may be  used to endorse or promote products derived from this software without  specific 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.
