As integration tests got slower and harder to run, we've put more and more pressure on our developers to simulate the other services in their cluster. This is a timesink that doesn't reliably predict whether code will run right on production. The solution is to move integration tests earlier, and make them more available for developers. Right now we're penalizing developers for 'breaking staging,' and otherwise writing code that fails at the integration test stage. Failing at integration testing should be as common as breaking unit tests.
