一个回归测试脚本
示例：my_PP4E/system/filetools/tester/tester.py
#!/usr/bin/env python
"""
##############################################################################
测试某一目录下的Python脚本，传入命令行参数，将stdin与管道相连，通过捕捉stdout、stderr和退
出状态来探测失败，以及获得前一次运行输出的回归记录。利用subprocess模块派生和控制流（类似Pyt
hon 2.X中的os.popen3），并可跨平台运行。流把它在subprocess中均为二进制字节。测试用到输入
、参数、输出、和错误均映射到子目录中的文件。
测试目录必须包含一个存放测试脚本的目录“Scripts”；如果有某个脚本需要获取命令行参数，则需在“A
rgs”目录下创建一个文件名为“除去.py后缀的原文件名 + .args”的文本文件；
如果需要输入，则需在“Inputs”目录下创建一个文件名为“除去.py后缀的原文件名 + .in”的文本文件；
“Errors”、“Outputs”等目录程序会自动创建。
这是一个命令行脚本，命令行参数均为可选，并不强制：第1个为测试的目录；若使用者输入参数“-f”或“
--forcegen”，则强制生成运行输出文件；若输入参数“-v”或“--verbose”，则显示详细运行情况。
