 // Common js for the HTML5_* tests. The following variables need to be defined
 // before this js is included:
 //   - 'willPlay' - indicates if the media is expected to start playing during
 //      the test.
 //   - 'testNetworkEvents' - if set to true, the test will test for the
 //     loadstart and stalled events. NOTE that since the loadstart event fires
 //     very early, to test for it reliably, the source of the media tag
 //     should be added after this script is included or add
 //     'onLoadStart=mediEventHandler' as an attribute to the media element.
