Python unittest如何生成HTMLTestRunner模块


生成 HTMLTestRunner 模块

unittest 里面是不能生成 html 格式报告的,需要导入一个第三方的模块:HTMLTestRunner

方法1.这个模块下载不能通过 pip 安装了,只能下载后手动导入,下载地址:

http://tungwaiyip.info/software/HTMLTestRunner.html

方法2.在 python 安装文件的 Lib 目录下新增文件 HTMLTestRunner.py

两种模板如下,建议使用第一种(第一种模板更加美观)

文件内容如下:

(1)第一种模板

# -*- 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" rel="external nofollow" rel="external nofollow" 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 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" rel="external nofollow" rel="external nofollow" type="text/css">'

  # run the test
  runner.run(my_test_suite)
