Back a year ago or so the phrase “dependency injection” kept rearing its ugly head and I couldn’t get away from it. Although I spent some time reading about it and could explain what it was, I never really understood it in terms of application. Then one day I stumbled across one of these videos while having lunch and it all started to make some sense, now that it had been given some context.

I’ve written a reasonable number of tests before on past projects but truth be told I’m still probably a bit of a n00b with the whole thing. Keep in mind though, the videos discuss how to write code that’s testable, not the tests themselves… Either way, what I like most about Miško’s talks is that the methods he demonstrates for writing testable code seem to enhance the overall quality of the code in a number of other dimensions. Now I just need a project to start applying all this stuff to. Yeah yeah, onto the videos…

For anyone new to Google tech talks, there’s a whole bunch more from other people also. I’ll continue to be taking my favourite ones and posting about them here.
