automating command line program

[Victor Chen]

More specifically, I'm trying to automate testing for a command line program. I've successfully launched the program and now the program is prompting me for some information. However, I'm not able to tell python to input the information which I would like to enter. I've tried os.popen, and os.system, but they will not input information into the program, instead, they will run after i break out from the program and tries to input the information into the windows command prompt in which will result in an windows command prompt error because the information is not recognized as a valid command. If I don't break from the program, then I will be at a halt because the program just keeps on waiting for input of the information and will not exit itself.

Further, I've looked up a module called the Expect module for python. Sometimes called Expectpy or expy but am unable to find a windows version of it.

I will look into popen2. Thank you.
