    DHH is essentially talking about how getting overly concerned with testing millions of isolated pieces is more trouble than it's worth.

        @wycats Makes sense if you are familiar with the code you are working on. Try walking onto a monolithic legacy app with millions of lines

        @chelseakomlo drawing conclusions from failures is just as problematic as survivor bias :)

        @wycats True :) All I'm saying is testing isolated pieces of code is helpful when you are fixing code that is huge, unfamiliar, and failing

        @chelseakomlo but the question is: where are the boundaries. My opinion: they're extracted as parts of your app stabilizes.

        @wycats Sure. Black boxes that just "work" can be fine. But when they break everyone longs for overly granular tests to identify the problem

        @wycats ok but how you can refactor your code without tests? It is amazingly convenient when you have them

        @shevchuk those are regression tests which DHH spoke well of

        @wycats Unless, of course, your product is being sold as a collection of millions of pieces.
