We have tests that errors are correctly trapped (data or pipeline code)

We also have detection and alarms if our pipelines don't run when they are supposed to or run for abnormal durations (too long or too short).

As part of a continuous improvement ethos when problems occur that are as yet not covered by tests we are always asking whether testing could have prevented the problem, if testing us currently possible and whether a different approach would make it testable.
