导入HTMLTestRunner到Python,生成测试报告的工具类 """ 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) ------------------------------------------------------------------------ Copyright (c) 2004-2007, Wai Yip Tung All rights reserved.
