thanks. you've got a good point there. if the test can't load the script that I want to run tests against, I want it to crash and just doing
require 'foo';
will do that.
but I prefer using the ok() or require_ok() with a die or croak (which I didn't include in my example) because then in a test suite I get better diagnostic:
not ok 2 - require foo;
# at /source/t/foo.t line 30.
# Tried to require 'foo'.
# Error: Can't locate foo.pm in @INC (@INC contains: /source/bin
+... at (eval 17) line 2.
Died at /source/t/foo.t line 30.
