the failed check stops the pipeline so the bad numbers never reach the dashboard, and someone gets paged instead.
Blocking data test
Also callederror severity test, circuit breaker test
A data test whose failure halts publication rather than merely recording a warning. Choosing which tests block is the whole design: block on everything and the pipeline stops nightly, block on nothing and the tests are decoration. The useful rule is that a test blocks when serving wrong data is worse than serving stale data, which is a question for the consumer.
