        <p>
            This test validates the value of window.performance.navigation.type with a forward
            and back navigation.</p>

        <p>This page should be loaded with a yellow background frame below.  It should turn green for a starting
            navigation, back to yellow for a back navigation and then back to green again for a forward navigation.</p>

        <p>Along the navigation timeline the frame.window.performance.type is checked for TYPE_BACK_FORWARD.</p>

        <p>This test passes if all of the checks to the navigation.type are correct throughout the navigation
            scenario and the frame below ends with a green background.  Otherwise, this test fails.</p>
