运行环境：python3+selenium

1.调用HTMLTestRunner运行未能输出报告：

检查pycharm运行代码名称是否加了unnittests

最简单的方法是使用Alt+Shift+F10，选择当前脚本运行

2.调用HTMLTestRunner运行输出HTML文件为空

度娘半天，终于解决，贴出修改后源码，记录一下也防止后人踩坑

直接替换HTMLTestRunner.py文件

修改后HTMLTestRunner下载地址：http://pan.baidu.com/s/1tp3Ts

源码如下：

"""

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 = ''

# run the test

runner.run(my_test_suite)
