Developer: “Last Sprint I delivered 18 story points all on my own!” This post will not be about story points. I will leave the story points are evil discussion for another time. Instead I want to focus on the intent behind such a statement. And by intent, I am referring to the proud declaration and feeling…

When you are coming up with a testing strategy for green field applications, you should follow the testing triangle or pyramid. For legacy application, a different strategy is needed. Writing tons and tons of unit tests when working with a very large application with zero tests is very costly and results in very little benefits. A…
Acceptance test driven development takes the TDD practice and applies it to acceptance tests.
