The following three tests fail on GTK because LayoutTestController::computedStyleIncludingVisitedInfo is unimplemented: fast/history/nested-visited-test.html fast/history/self-is-visited.html fast/history/sibling-visited-test.html Platform-specific failing results have been checked in for them. But we should implement this LayoutTestController API so we can pass them!
The function is now implemented and all three tests passing. http://trac.webkit.org/browser/trunk/Tools/DumpRenderTree/gtk/TestRunnerGtk.cpp#L110 http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=fast%2Fhistory%2Fnested-visited-test.html%2Cfast%2Fhistory%2Fself-is-visited.html%2Cfast%2Fhistory%2Fsibling-visited-test.html
