            Bug ID: 203262
           Summary: Web Inspector: frontend tests should clear output
                    before resending results
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: yurys at chromium.org
                CC: inspector-bugzilla-changes at group.apple.com

FrontendTestHarness._resendResults should clear output before re-adding results to the test output after navigation. Otherwise there is a race between TestPage.addResult commands that are sent after navigation started but before InspectorTest.testPageDidLoad is called again. Such in flight commands may be sent to the new page second time from _resendResults introducing flakiness to the tests that rely on navigation.
