  • Hybrid interface testing
    Patent number: 11789854
    Abstract: A user interface testing system, method, and device for a vehicle under test (“VUT”). A test system is communicatively coupled to the VUT. A test system records outputs of at least one human-machine-interface (“HMI”) responsive to a first set of test cases and then scores the recorded HMI outputs responsive to the first set of test cases. The test system generates a second set of test cases and scoring criteria for the second set of test cases based on the received first set of test cases and the recorded HMI outputs responsive to the first set of test cases. The test system performs the second set of test cases on the HMI and records HMI outputs responsive to the second set of test cases. The test system assigns scores for the recorded HMI outputs responsive to the second set of test cases using the generated scoring criteria.
