Should all methods be static if their class has no member variables

Question

I\'ve just had an argument with someone I work with and it\'s really bugging me. If you have a class which just has methods like calculateRisk or/and calc

Answer 1

It depends what your goal is:

If your goal is to write as few lines of code as possible, the static approach would be the best.

If your goal is testability, we've discovered that static methods are a bugger to mock out. We, sadly, end up writing an interface, and a class for some of these just to be able to mock them out easily.
