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

In this case, I would probably make a couple of static methods. I would assume that the calc function does not depend upon other resources to calculate the values, and it is generally segregated from the rest of the code.

In general, however, I tend to shy away from doing overly complicated things in static methods. If you were unit testing and wanted to swap in a MockCalcService, having the static calls spread out across your code would make it very difficult.
