That's not a bad perspective, but the counterpoint that I have seen several times is that the tests can tend to take on a split quality where some will insist that nothing can be changed if a test has to be changed along with it - and then the other camp steps in and doesn't want to put in the effort for new tests, so the existing ones get removed. Testing makes a lot of sense if you're doing data munging, but for front end or other kinds of code that are almost defined by their ability to create side effects, it's usually a waste of time. In my humble.
