Note that during verification, a failed verification doesn't return an error Result, but failed configuration or core bugs will. This is the intended default behaviour - as a failed verification doesn't necessarily indicate a problem in the code that is being verified. **Signature:** ```typescript verify(): Promise; ``` **Returns:** Promise<[BoundaryResult](./case-boundary.boundaryresult.md)> a promise that indicates the result of verifying this test (BoundaryResult)
