Hi jaypal,

I have written a Perl framework which uses those modules which you mentioned in your post, my framework will take the test cases as YAML file format. my framework is well suited to test CLI based commands.

YAML file is nothing but has command to execute, output to match. So when my framework runs it takes the command from YAML file and executes and matches with the expected output you configure. so if it matches it passes otherwise fails.

Finally it gives an Excel file consist the passed and failed test cases with status and why it failed like what was expected and what was the actual output. If you are interested in this please get touch with me. I can guide you.
