First, is it fast?

Faster test feedback means catching issues earlier or feeling confident about changes earlier, either way, we're moving faster

Second, is it deterministic, i.e. not flaky?

A flaky test is a test that fails nondeterministically, without any code change.

Flaky tests have a double tax: you need to rebuild AND you lose confidence in your tests so you slow down your rate of change to lower risks.
