> Spinning up a local instance of postgres defeats the whole purpose of an end-to-end test. So run some end to end test in a fully featured staging-style environment as well? I'm not disagreeing at all that having some environment that closely resembles production for very late phases as well is nice to have. I'm arguing against nonsense like mocking out database calls because of weird superstitions. > And network latency and transfer speeds mean that taking more than 100ms may happen often. The operative word being "may". If your staging server in Timbutku needs to talk to your other staging server on the South Pole you will blow your 100ms window all the time. If it all runs within a single good DC, network latency ought to be ~0.1ms roundtrip and you can shovel around Gigabytes per second.
