Can we not have articles like this with blanket statements like this please? As with everything in software, no one size fits all. Mocks have their place. There are situations when the only way we can test something out is to mock out a certain function call. Sometimes our dependencies are so complex and deep that we cannot just replace it with a fake. But with a little mock we can replace a function or a class within that dependency to decouple our tests from it.

Having a title with a blanket statement like "Don't Use Mocks" is either plain wrong or clickbait. In this case, it seems it is both wrong and clickbait. Such blanket statements and clickbaits specifically trigger people to get into a long-winded debate (ironically, my own comment here is a case in point) about something that is obvious and otherwise uncontroversial.
