-/*
- * This script is used for menu and popup tests. Call startPopupTests to start
- * the tests, passing an array of tests as an argument. Each test is an object
- * with the following properties:
- *   testname - name of the test
- *   test - function to call to perform the test
- *   events - a list of events that are expected to be fired in sequence
- *            as a result of calling the 'test' function. This list should be
- *            an array of strings of the form "eventtype targetid" where
- *            'eventtype' is the event type and 'targetid' is the id of
- *            target of the event. This function will be passed two
- *            arguments, the testname and the step argument.
- *            Alternatively, events may be a function which returns the array
- *            of events. This can be used when the events vary per platform.
- *   result - function to call after all the events have fired to check
- *            for additional results. May be null. This function will be
- *            passed two arguments, the testname and the step argument.
- *   steps - optional array of values. The test will be repeated for
- *           each step, passing each successive value within the array to
- *           the test and result functions
- *   autohide - if set, should be set to the id of a popup to hide after
- *              the test is complete. This is a convenience for some tests.
- *   condition - an optional function which, if it returns false, causes the
- *               test to be skipped.
- *   end - used for debugging. Set to true to stop the tests after running
- *         this one.
