I've seen a lot of tests where people just mock everything by default without thinking. Smart programmers at a good company. It's an issue that does deserve more recognition. Abuse of mocks is bad for tests.
I know which company you are talking about :). I agree that abuse of mocks is bad for tests 100%. But when I clicked the link I was hoping to read an article giving a nuanced description of mocks, with some analysis on when to use and when to avoid mocks. Instead the article is just an opinion piece that just says "Stop using mocks" as if that was actually an option.
