The test is intended to fail because the change of user agent was not expected.
The browser must be JavaScript-enabled.

“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case fails the following success criterion at line 10, column 161: http://www.w3.org/TR/2007/WD-WCAG20-20070517/Overview.html#consistent-behavior-no-extreme-changes-context.
The user initiated the change of context, but did not expect it to be connected to the user's action.
The actual behaviour may depend on the user agent. On Windows XP, the following behaviour was observed. In Internet Explorer, the audio file was loaded in an instance of Windows Media Player. In Firefox 2.0 and SeaMonkey 1.1, audio file was played by QuickTime (in the same tab as the referencing file). In Opera 9.0, it is not clear how the behaviour should be explained: when pressing a (to cycle through links), the page becomes blank but the URL does not change; no music starts playing.
This test case maps to failure F22: Failure of SC 3.2.5 due to opening windows that are not requested by the user.
