Titus suggested I post some of the links I keep sending him, so here they are:
Darren Hobbs talks about "Why a 20 minute build is 18 minutes too long". The build in question included acceptance tests. His conclusion is that I/O is the enemy. My take on it is that a continuous build system should run all the unit tests, plus a subset of acceptance tests that are known to run fast. The other acceptance tests, especially the ones that do a lot of I/O, can be run more leisurely, once every X hours.
Michael Hunter, aka The Braidy Tester, posts his impressions on Uncle Bob's SDWest talk on Agility and Architecture. I particularly enjoyed this point: "The first, most important part of making code flexible is to surround it with tests."
Tim Ottinger (from ButUncleBob's crew) blogs on his experience with Testing Hypothetically. It's all about seeing the big picture when writing acceptance tests, and not being bogged down in the implementation-specific details that are best left to the realm of unit testing.
Brian Marick tells us to pay attention when finishing a story. Is the system better off (more malleability is what Brian is looking for) now that the story is done?
Roy Osherove posted the first article in what I hope is a long series on "Achieving and recognizing testable software designs". He discusses a problem that I also raised in the Agile Testing tutorial at PyCon: writing good unit tests is hard. But thinking about making your system testable will go a long way toward increasing the quality of your system. And Roy proceeds with practical recipes on how to achieve this goal. Great article.
While I'm mentioning unit testing articles, here's another good one from Noel Llopis's Games from Within blog: "Making better games with TDD". I haven't seen too many articles on developing games in a TDD manner, and this one really stands out. I particularly enjoyed their discussion of when and when not to use mock objects. A lot of lessons learned in there, a lot of food for thought.
Andrew Glover writes about FIT in his IBM developerWorks article "Resolve to get FIT". Nothing too earth-shattering, but it's always nice -- at least for me -- to see tutorials/howtos on using FIT/FitNesse, since it's an area I feel it's under-represented in the testing literature (but some of us are on a mission to change that :-)
Finally (for now), via Keith Ray, here are Agile Development Conversations in the form of podcasts.
I'm thinking about periodically posting stuff like this. Of course, I could just post my del.icio.us bookmarks, but going through the articles and commenting on them a bit helps me in committing the highlights to memory.
