unittest 报告——HTMLTestRunner/BSTestRunner+代码覆盖率

1. HTMLTestRunner.py 代码（python3）如下:

python2:  https://github.com/tungwaiyip/HTMLTestRunner

 """
 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)

 """
 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 BSTestRunner

     ... define your tests ...

     if __name__ == '__main__':
         BSTestRunner.main()

 For more customization options, instantiates a BSTestRunner object.
 BSTestRunner is a counterpart to unittest's TextTestRunner. E.g.

     # output to a file
     fp = file('my_report.html', 'wb')
     runner = BSTestRunner.BSTestRunner(
                 stream=fp,

                 description='This demonstrates the report output by BSTestRunner.'
                 )

     # 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)

pip3 install coverage

 coverage3 run ttst.py #上面代码的主运行文件
 coverage3 html

会生成htmlcov 的文件夹，打开index.html
