           Summary: NRWT support of per-test args and pass --pixel-tests
                    in per-test args
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: wangxianzhu at chromium.org
                CC: dpranke at chromium.org


For now, when running NRWT with --no-pixel-tests, DriverProxy maintains two drivers one of which run non pixel tests and one run ref tests.
This causes problem of chromium-android which doesn't support multiple drivers on one device. On chromium-android we don't use DriverProxy but restart the single driver when pixel-test mode changes. Bug 91533 groups the ref tests together to reduce the cost of restarting the driver on chromium-android.

The problem would be resolved if we can let one driver/DRT support support both pixel and non-pixel tests, that is, the --pixel-tests should be passed as a per-test arg instead of a command-line parameter to DRT.
