How Does TDD Affect Design?

TDD doesn't create good design. You do. TDD can help expose design smells. You have to pay attention and fix them. TDD can push you toward facile solutions. You have to be careful not to make your design worse just to make testing better.

Naming (Or How Names Can Be Ambiguous)

A really simple way to add an additional layer of information to an architecture diagram (and to remove any ambiguity) is to annotate boxes with a very short statement of what their responsibilities are. A bulleted list (7 ± 2 items) or a short sentence work well.

StackStorm Takes a Modernized Shot at DevOps

If DevOps is a verb and DevOps is a change in culture, does it make sense for anybody to call themselves a DevOps startup? Sort of. Especially if they’ve done it before.

TDD When You Can't Refactor

Maybe Rails apps are too sophisticated in terms of coding constructs to be easily and cheaply test driven. At least compared to Java. Maybe frameworks are harder to TDD too, compared to libraries. Refactoring, in tools like Intellij for Java, is like giving the Mona-Lisa a proper smile with your fingers, hundreds of years after the last brush stroke, and perfectly. Not only that, but Intellij’s local-history undo is perfect too. Don’t like that smile? Hit Ctrl-Z.
