| // Exhaustive enum-completeness testing would require multi-facing-mode |
| // hardware (or mock-device infrastructure that honors the facingMode |
| // option through to getSettings — WebKit's addMockCameraDevice |
| // currently does not). What we can verify is the narrower |
| // spec-conformance claim: any value WebKit returns through |
| // getSettings().facingMode or getCapabilities().facingMode entries must |
| // be one of the four enum values. A value outside this set would be a |
| // spec violation regardless of which subset WebKit's mocks expose. |

| // TODO: when mock cameras honor the facingMode constructor arg through |
| // to getSettings(), extend this test to verify all four values |
| // round-trip through the IDL binding. |
