Id love to agree with this but my experience differs on modern stacks. We so often mock or stub APIs, use a web driver that's pinned to a certain version of WebKit, test against virtual dom, etc that it's hard to get real reliable test results that don't break all the time.
But I suppose that's the problem; we don't have the time to fix bugs related to the environment that crop up when no code changes so we insulate our tests from the environment by design.
