+ *
+ * The request has two types, audible and inaudible request. The result of the
+ * audible request would only take effect on audible media, and the result of
+ * inaudible request would only take effect on inaudible media.
+ *
+ * User activation policy still work on GeckoView, so once the page has been
+ * activated, then we won't have to send the request and would allow all media
+ * in that page to play.
+ *
+ * The following test cases contain the information which would be applied in
+ * test, and the expected result of the test. For example, the following info
+ * indicates that, play an [inaudible] media in the environment with [allowed]
+ * [audible] request, and we expect to see it plays successfully.
