in reply to A test harness for scripts

Well, what I'd say more than anything else is: put as little logic as possible in your scripts. Make them just executable wrappers around your modules, and then write test cases for your modules.

Beyond that, yes, it would be cool to have script harnesses (although, my limitted experience with IPC::Run would lead me to recomend it over IPC::Open3).

Last, as for testing web servers: what we do where I work is we actually wrote a web replay agent, which reads in apache logs and issues requests to the web server, logs the output and diffs it against the expected results. We've been trying to push the idea to management of getting this test harnass released to open source... but no luck yet. Anyway, the idea is pretty straight-forward, though.
