That sentence is only true if your tests are bug-free. If not, it's
possible to make a change that introduces a bug that passes testing
because of a bug in the tests. Since tests are code, they're never
bug-free. I will agree that the frequency of upgrades/updates breaking
things means testing isn't being done properly.
