in reply to Genome UV Mutation Script -- Critique

Thank you all for your input. Although I didn't check CPAN before I started writing this, I'm not surprised that someone else has solved this problem before. I don't get enough opportunities at work to flex my perl muscles and thought this would be a great learning experience (as it has been). I will look into references, I definitely didn't understand them the first time through Larry's Programming Perl, and it seems from your comments, that they warrant a second look. Thanks again! I really appreciate everyone's input!

[marinersk]: sub newtest{my $expected_result = &target('foo'); my $actual_result = &target('foo'); if ($actual_result eq $expected_result) { &tdd_success(); } else { &tdd_fail(); } } # Test works after three years!
[choroba]: or nobody bothered...
[choroba]: The problem was bigger, as the test tried to call a method that didn't exist anymore
[marinersk]: :: ducking ::
[choroba]: because, someone renamed the method, but didn't notice it was used in the test, as the test was skipped
[marinersk]: Well, if the method doesn't exist, it would be hard to pass the test.
[choroba]: later, someone removed the new method, as all its usage places were safe, but didn't notice the test still used the old name
[choroba]: fortunately, it wasn't that hard to replace the method and fix a few remaining failures due to the changes we did to the codebase over the years
[marinersk]: choroba Sounds like a process improvement opportunity; tests may not all need to be run, but they should all be compiled with perl -c before check-in/promotion happens.
[choroba]: so, now I have the test, so I can start making changes in the code. Back to the original ticket, yay!
