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