to test my libraries..I now want to use it to test a Gtk2 perl app I've written. I want to do things like select a bunch of items in a SimpleList and hit a button, this objects are global variables in my main program, call it foo.pl..whats the best, cleanest way to launch my program from within foo.t test and interact with it..I'd like to keep readability of the test at a maximum, at the cost of efficency of the test it's self if I must.
