+// Tests various output of the computed-view's getNodeInfo method.
+// This method is used by the HighlightersOverlay and TooltipsOverlay on mouseover to
+// decide which highlighter or tooltip to show when hovering over a value/name/selector
+// if any.
+//
+// For instance, browser_ruleview_selector-highlighter_01.js and
+// browser_ruleview_selector-highlighter_02.js test that the selector
+// highlighter appear when hovering over a selector in the rule-view.
+// Since the code to make this work for the computed-view is 90% the same,
+// there is no need for testing it again here.
+// This test however serves as a unit test for getNodeInfo.
