发现163的博客，还是不太适合写技术类的东西，特别是代码处理的很不舒服，就搬迁到这里了，学习继续进行。

添加一段代码试试：

1 def run_tc(tc_folder, output_folder, case_name, env_name, parameters, logfile):    2     """ 3     run a test case 4     return: result in a string 5     """ 6     # check Python version 7     if sys.version_info[:2] < (2,7): 8         print("Current Python verion "+sys.version.split()[0]+" is not supported, please use 2.7 or higher") 9         sys.exit()10     11     output_folder=os.path.abspath(output_folder)12     tc_folder=os.path.abspath(tc_folder)13     14     # change working directory to where the test case loacted15     os.chdir(os.path.join(tc_folder, os.path.split(case_name)[0]))16     17     # initialize log18     log_format="%(asctime)s %(levelname)-8s %(name)-8s %(message)s"19     logging.basicConfig(format=log_format, level=logging.DEBUG)
