It really depends what one is building. As you point out, in your example, testing is very useful since it allows you to be confident that your code works. Some of the backlash around testing is about testing things that really shouldn't need to be. If there's a mandate from some clueless management that all code must be covered by tests and the new code is simple data containers, then one ends up having to write tests for methods like getValue() { return value; }, which is a bit absurd. I'm assuming the author of the article is in the latter situation, not the situation you describe where tests are actually useful.
