I'm not sure if it's worth it having a test that fails on all platforms. What is the specific issue in EventSender? Linking to bug 42194 is not helpful in this regard. Mac DumpRenderTree has the code to send wheel events, so this seems like an overly broad statement that eventSender cannot simulate mouse wheel events. 975897 8 bfulgham 2014-02-03 09:49:15 -0800 (In reply to comment #7) > What is the specific issue in EventSender? Linking to bug 42194 is not helpful in this regard. Mac DumpRenderTree has the code to send wheel events, so this seems like an overly broad statement that eventSender cannot simulate mouse wheel events. I've been wrestling with this issue the past couple of days. I have filed https://bugs.webkit.org/show_bug.cgi?id=127606 to extend eventSender to support wheel events better. I do agree that the current infrastructure can send wheel events, but it is not currently capable of supporting gestures (such as a "flick" of the mouse wheel) that involve multiple mouse wheel phases and momentum support. I'm not sure if those shortcomings are relevant to this particular test case. For example, it might be possible to use the 'scrollTop' property of the scrollable region to confirm that the mouse operations caused the region to scroll. 975901 9 222988 bfulgham 2014-02-03
