During standard pre-launch or manufacturing tests. It should be verified by applying some change and checking that this change is measured correctly.
Generally for critical sensors, you can add some circuitry or even mechanical means of checking (eg heater on temperature sensor). If mechanical side fails, whole sensor module is marked as failed. Critical sensors should be designed in a way that you know when it fails.
