AssertMeasurement

Learn AssertMeasurement in Q# with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Advanced

AssertMeasurement is an atomic Q# topic inside Testing & Resource Discipline. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what AssertMeasurement changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

qsharp-08-01-assertmeasurement.qs
qsharp Try It Live
operation Demo(q : Qubit) : Unit { AssertMeasurement([PauliZ], [q], Zero, "expected |0>"); }
Edge case / engineering note

Exercise both the success path and the failure path; verify what is caught, propagated, or cleaned up rather than only checking printed output.
