Okay, so apparently I got completely off-track, so this is a major interlude here. I actually have the next post in the pipeline.
Anyway, I came across this and thought it was a really good read and explanation of something similar to what I think.
There are some differences. For instance, since I dislike TDD so much, I’d change all references to Context/Specification testing.
But, it is a very concise and clear summary. Take a look.
