           Summary: NRWT: confusing warning about a line being in a
                    Skipped file when it is really just listed in
                    _missing_symbol_to_skipped_tests in base.py
           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

When running run-webkit-tests, I am seeing the following warnings:

LayoutTests/platform/mac/TestExpectations:1033 /Volumes/Users/jessieberlin/Source/Safari/Opensource/LayoutTests/platform/mac/TestExpectations:1033 fast/css/variables is also in a Skipped file. fast/css/variables
LayoutTests/platform/mac/TestExpectations:1034 /Volumes/Users/jessieberlin/Source/Safari/Opensource/LayoutTests/platform/mac/TestExpectations:1034 inspector/styles/variables is also in a Skipped file. inspector/styles/variables

This is happening because ‘fast/css/variables’ and ‘inspector/styles/variables’ are listed in _missing_symbol_to_skipped_tests as well as being listed in that TestExpectations file.

    # Ports which use compile-time feature detection should define this method and return

    # When the symbol substrings are not matched, the directories will be skipped.

I talked with Eric Seidel and Dirk Pranke about this on IRC. We should just remove this code. ORWT used to detect if you had SVG compiled into your binary and auto-skip relevant tests, and this was added to support that. Dirk also noted "there's a separate similar code path for "runtime" feature detection that IIRC was only needed for the apple win port and probably never really worked right there, either."
