To add another string to my bow, I'm going to learn RSpec in depth, and have an application in mind for writing and learning RSpec via, makes more sense to at least enjoy myself while I'm learning!
Currently I'm working my way through the PeepCode screencasts on the subject, so I might be quiet for the next few days...
I spent last Friday/Saturday at Scotland on Rails and for a conference in it's first year, it was both really enjoyable and packed with really good talks.
A focus for many of the talks was testing, whether that be TDD, SDD or BDD! This was interesting aspect of the conference for me, as both personally and in a work environment, I find it hard to dedicate the right amount of time to testing.
The more application development I do in Rails, I believe it's important to both test and test correctly and the talk I enjoyed the most on testing, was the talk by Tammer Saleh on shoulda. I think the reason this talk impressed me was that Tammer personally wrote shoulda and therefore was obviously enthusiastic about the plugin!
Therefore, my next task (after learning more Ruby, more about that soon!) will be to delve in depth into testing.
