Let's say you have this prog.pl:

#!/usr/bin/perl sub do_something { return 42; } print "Running\n";

and this test.pl:

#!/usr/bin/perl require 'prog.pl'; print "ok 1\n" if do_something()==42;

Now, running test.pl produces:

Running ok 1

because the require will execute the program. So, if the program dies because @ARGV is wrong, or somesuch, your test dies as well...
