A method of performing an on-wafer function testis provided for multiple magnetic field sensor elements on a wafer. Each sensor element includes a magnetic-field-sensitive structure and a current conductor structure. The current conductor structure provides a test magnetic field in response to a test signal, and a change in an electrical characteristic of the respective magnetic-field-sensitive structure is sensed. The functionality of the respective magnetic field sensor element is then evaluated based on electrical characteristic change.
