Testing, testing…

I’ve been adding tests to one of the Perl modules I have written for the buildtools project. This is for two reasons, firstly, it’s good to have tests for the code as it helps spot bugs and makes it easier to add further functionality safe in the knowledge that none of the earlier work has been broken. Secondly, I wanted to try out a few testing strategies which might be useful when it comes to the LCFG core refactoring project. I have been playing with Devel::Cover which measures how much of the code is covered by the test suite – here’s some results. My initial trials suggest this is quite a good strategy as it encouraged me to think about all the different pathways through the code and it did find one rather nasty bug.
