/**
 * Test that messages can be sent from the browser to the server,
 * and sent from the server to the browser.
 *
 * For reference:
 * 1) Initially tried HtmlUnit, but it could not receive messages from the server.
 * 2) Tried using WebDriver implicit wait times with the following:
 * driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 * but made the client unable to send or receive messages, thus we use sync()/sleep().
 *
 * FIXME Graphene2 should handle timeouts better using requests Guards and Waits
