Instead of passing in two ports here, we could return two ports. If you call
listen on HttpServer without a port argument, it will use any available port.
That port can the be retrieved from the HttpServer instance and be returned
here. Those two port numbers can then be used in the URL for the test so that
the tests themselves are independent of the actual port numbers. That would
avoid issues when the hard-coded port numbers are already in use (either because
of other test scripts running or because those ports are used for other things).
