Test::More & interactive testby pileofrogs (Priest) |

pileofrogs has asked for the wisdom of the Perl Monks concerning the following question: Greetings Monks! Yes, I know I shouldn't have interactive tests. I'll make them all automated or optional or something later. Maybe I'll use expect. Basically, I'm writing some stuff that will alter user accounts on a system and send them email to tell them what it did. I want the script to run vi so I can review the email and make edits before it gets sent. In the test harness, vi gets all confused because STDOUT isn't a tty. I can see the text to edit and I can close vi by typing "<esc>:q!" but I can't see the cursor or anything I type. No, this is not a surprise. I think I need a way to tell the test harness to give me back the TTY for a minute, to stop looking for TAP and then start again. If I run system("vi $filename") it behaves like I describe. If I run system("vi $filename >&2") it works great (vi still complains, but I don't care.) If I redirect STDOUT to STDERR and back in the test script, it doesn't help. I guess that's what you'd expect because STDOUT is already screwed with before I get there so redirecting it after the fact isn't going to help. Anyway, is there a good way to handle this? I'm interested not only to solve my problem but also to improve my understanding of all these interacting filehandles and whatnot. Here's the shortest script I could think of that shows the situation. Obviously you need 'vi' in your path.
Thanks All!
