if __name__ == "__main__":    
    # runner = unittest.TextTestRunner()    
    # runner.run(all_case())    # html报告文件路径
    report_abspath = os.path.join(report_path, "result.html")
    fp = open(report_abspath, "wb")
    runner = HTMLTestRunner.HTMLTestRunner(stream=fp, title=u'自动化测试报告,测试结果如下：', description=u'用例执行情况：')    # 调用add_case函数返回值    runner.run(all_case())
    fp.close()

先这么操作试一试，实在不行再根据网上资料调整。或者你自己根据错误去一步一步调试：

  if __name__ == "__main__":
      suite = unittest.TestSuite()
      suite.addTest(QQLogin("test_01"))
      # runner = unittest.TextTestRunner()
      # runner.run(all_case())
      # html报告文件路径
      report_abspath = os.path.join(r'E:\github\Python\Appium\report', "result.html")
      fp = open(report_abspath, "wb")
      runner = HTMLTestRunner.HTMLTestRunner(stream=fp, title=u'自动化测试报告,测试结果如下：', description=u'用例执行情况：')
      # 调用add_case函数返回值
      runner.run(suite)
      fp.close()
  
  您给的方法 不用HTMLTestRunner运行就不报错，用就报错

  HTMLTestReportCN.py就以这个命名吗？还是python目录就有这个文件呢？我电脑找不到这个文件  只有一个HTMLTestRunnrt.py

  对的，就是HTMLTestRunner 哪个report也是。我给你的代码也是htmlttestrunner了的。你就按照我上面执行就ok。还有你htmltestrunner的因该是python2 换一个python3的

• 提问者 HelloPython01 回复 Mushishi #3

  我在官网下载的HTMLTestRunner是py2的吧  之前是生成不了测试报告 原因在网上查了  也对应的修改了HTMLTestRunnr.py 的语法     
  
  
  另外有个html-testRunner 1.2.1     这个也跟HTMLTestRunnr用法一样吗 ？好像是python2 python3都能用？
