Test case

Each mouseover throws this error:

[Error] TypeError: undefined is not a function (evaluating 'element._createTooltipForNode()')
	_onmousemove (DOMTreeOutline.js, line 313)
	(anonymous function) ([native code], line 0)

To reproduce, in the attached 501nodes.html file, inspect the dom and mouse over the "Show All Nodes" button below.

I think it might be better just to test for the presence of the "_createTooltipForNode" property, instead of doing an instanceof check. This is basically a delegation protocol, and those usually work best when they are agnostic about the type of the target object, and only check whether the target object responds to the delegate function.
Comment 7 Geoffrey Garen 2014-06-24 11:36:34 PDT
Also, can you add a Web Inspector regression test to this patch?
Comment 8 Timothy Hatcher 2014-06-24 12:21:13 PDT
We don't have Web Inspector UI regression tests. We only have tests for the protocol and model layers.
