-// Tests that the right platform-specific accessibility events are fired
-// in response to things that happen in a web document.
-//
-// Similar to DumpAccessibilityTree in that each test consists of a
-// single HTML file, possibly with a few special directives in comments,
-// and then expectation files in text format for each platform.
-//
-// While DumpAccessibilityTree just loads the document and then
-// prints out a text representation of the accessibility tree,
-// DumpAccessibilityEvents loads the document, then executes the
-// JavaScript function "go()", then it records and dumps all accessibility
-// events generated as a result of that "go" function executing.
-//
-// How each event is dumped is platform-specific, but should be of the
-// form:
-//
-// <event> on <node>
-//
-// ...where <event> is the name of the event, and <node> is a description
-// of the node the event fired on, such as the node's role and name.
-//
-// As with DumpAccessibilityTree, DumpAccessibilityEvents takes the events
-// dumped from that particular html file and compares it to the expectation
-// file in the same directory (for example, test-name-expected-win.txt)
-// and the test fails if they don't agree.
-//
-// Currently it's not possible to test for accessibility events that
-// don't fire immediately (i.e. within the call scope of the call to "go()");
-// the test framework calls "go()" and then sends a sentinel event signaling
-// the end of the test; anything received after that is too late.
