Too Long; Didn't Read
The real challenge (and art!) of data testing is how you detect data problems and how you respond to them. The first line of response to a failed data test, before any humans are notified, are automated responses of the system to the test failure that decide whether and how to continue any pipeline runs. Who will actually see and respond to those notifications? Some factors to take into account are: Who gets notified and when? Upstream data producers, downstream data consumers, the team that owns the data pipelines, anyone else?
