Follow-up: Coding for Testability

I got a few comments (3) when I posted up about coding for testability. Paul took the time to post a detailed comment which came out kind of mangled and then followed up on his blog. Paul extends the pattern, essentially adding a fair bit more code and structure – this is a good thing if you can keep it up, but I wonder if I did a spot inspection of Paul’s code whether he had used it uniformly ().

Actually - the main point that I wanted to make is what effect a simple change can have on testability. I also think that if you can be more surgical in which parts of the program you mock with test harnesses you can reach into different parts of the code. This helps you test specific things, but it also helps drive your code coverage up.
