+\class TestHTTPServer
+\brief provides a very, very basic HTTP server for testing.
+
+Inside the test case, an instance of TestHTTPServer should be created, with the
+appropriate port to listen on. The server will listen on the localhost interface.
+
+Directories to serve can then be added to server, which will be added as "roots".
+Each root can be added as a Normal, Delay or Disconnect root. Requests for files
+within a Normal root are returned immediately. Request for files within a Delay
+root are delayed for 500ms, and then served. Requests for files within a Disconnect
+directory cause the server to disconnect immediately. A request for a file that isn't
+found in any root will return a 404 error.
+
+If you have the following directory structure:
+
+\code
+disconnect/disconnectTest.qml
+files/main.qml
+files/Button.qml
+files/content/WebView.qml
+slowFiles/slowMain.qml
+\endcode
+it can be added like this:
+\code
+TestHTTPServer server(14445);
+server.serveDirectory("disconnect", TestHTTPServer::Disconnect);
+server.serveDirectory("files");
+server.serveDirectory("slowFiles", TestHTTPServer::Delay);
+\endcode
+
+The following request urls will then result in the appropriate action:
+\table
+\header \o URL \o Action
+\row \o http://localhost:14445/disconnectTest.qml \o Disconnection
+\row \o http://localhost:14445/main.qml \o main.qml returned immediately
+\row \o http://localhost:14445/Button.qml \o Button.qml returned immediately
+\row \o http://localhost:14445/content/WebView.qml \o content/WebView.qml returned immediately
+\row \o http://localhost:14445/slowMain.qml \o slowMain.qml returned after 500ms
+\endtable
