@User I didn't think you were having a go at me at all. I know and am frustrated by current system, but can't change it yet.
And unfortunately most managers/POs/people watching time don't see immediate return then it isn't necessary and when working with such a legacy app they want all or nothing coverage quickly vs just working up coverage as you go which makes it very difficult to say, hey let me spend an extra hour to get some testing up and running so we can start small.
