1## 10.2\. CTS Verifier 2 3The CTS Verifier is included with the Compatibility Test Suite, and 4is intended to be run by a human operator to test functionality that cannot be 5tested by an automated system, such as correct functioning of a camera and 6sensors. 7 8Device implementations: 9 10* [C-0-1] MUST correctly execute all applicable cases in the CTS verifier. 11 12The CTS Verifier has tests for many kinds of hardware, including some hardware 13that is optional. 14 15Device implementations: 16 17* [C-0-2] MUST pass all tests for hardware that they possess; for instance, 18if a device possesses an accelerometer, it MUST correctly execute the 19Accelerometer test case in the CTS Verifier. 20 21Test cases for features noted as optional by this Compatibility Definition 22Document MAY be skipped or omitted. 23 24* [C-0-2] Every device and every build MUST correctly run the CTS Verifier, 25as noted above. However, since many builds are very similar, device 26implementers are not expected to explicitly run the CTS Verifier on builds 27that differ only in trivial ways. Specifically, device implementations that 28differ from an implementation that has passed the CTS Verifier only by the 29set of included locales, branding, etc. MAY omit the CTS Verifier test. 30
