For me the highlight of this post is the idea (that I think I only absorbed about a year ago, after over 3 months of testing) that testing, much like project management, is a practical toolkit, not a theoretical framework.

What this means is that you don't need to come up with The Way of doing testing correctly - just apply the tools and techniques that seem to work best for the current context, even if they're in contradiction with something that you did before on another project or even in another part of this project.
