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：
