           Summary: Layout test output can be dependent on tests run
                    previously
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mpComplete at gmail.com


Run this command (all one line):
run-webkit-tests
dom/html/level1/core/documentinvalidcharacterexceptioncreateentref.html
dom/xhtml/level2/html/frame.xhtml 


The second test will fail.  The frame.xhtml test has dependencies on previous
test runs*.  The reason it doesn't fail normally is that run-webkit-tests
restarts DumpRenderTree every 1000 tests, and during normal execution,
frame.xhtml is run in a more "fresh" DumpRenderTree.  (Another way to see this
failure is to bump up the testsPerDumpTool to a large value, say 10000).

* The specific dependency here is that KJSProxy::m_handlerLineno is not reset
between pages in some cases.  This shows up in the DRT output as a CONSOLE
MESSAGE with an invalid line number.
