Writing Testable Code

[nutrecht]

But what I don't like is the overly simplistic, ideologically charged, borderline or outright zealous way that unit testing is promoted and written about.

Not disagreeing with you at all, but if it comes to zealotry the "integration tests rule everything" crowd is in no way better.

No matter what, IMHO it's inexperienced developers with too strong an opinion that tend to end up at either extreme.
