TDD, Agile, Scrum, XP etc are a religion.
And a lot of people have managed to make their lives easier by making the teachings of this religion mandatory. So what I've been witnessing the last few years is that saying "no I don't think we need a test for this" is a position that will get you no where. So instead every one just puts up with longer and longer build times and spending more time each day fixing broken tests.
