HTMLTestRunner下载地址：

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

下载后存放在\python\Lib\site-packages下

验证是否导入成功：

python3中用HTMLTestRunner.py报ImportError: No module named 'StringIO'如何解决

1.原因是官网的是python2语法写的，看官手动把官网的HTMLTestRunner.py改成python3的语法：

2.修改汇总：

第94行，将import StringIO修改成import io

第539行，将self.outputBuffer = StringIO.StringIO()修改成self.outputBuffer = io.StringIO()

第642行，将if not rmap.has_key(cls):修改成if not cls in rmap:

第766行，将uo = o.decode('latin-1')修改成uo = e

第772行，将ue = e.decode('latin-1')修改成ue = e

第631行，将print >> sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime)修改成print(sys.stderr, '\nTime Elapsed: %s' % (self.stopTime-self.startTime))

生成测试报告（TestCase还是使用之前的）：
