-\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
