Python2 HTMLTestRunner自动化测试报告美化

python2 的测试报告美化，需要的同学直接用

 #coding=utf-8
 """
 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)
