I’m probably not the only one who had a chance to participate in deliberations over whether some private method should be tested (because it’s worth it) or not (because we shouldn’t test private methods). I’m not writing about pure theoretic conversations while you’re filling your cup of coffee and talking with your colleagues. I believe that in those moments most of developers would tell you a firm NO.
But what about situations when you are working with real code? When all those rules and principles are not so strictly followed? Would they also say NO so firmly? Based on my experience, I can tell you they wouldn’t. At least not always.
Ok, but should they? Should we? Or is it yet another nice-to-follow rule the observance of which depends on context?
