Solve the following python programming problem given the following code:
@ unittest.skipIf (is_jython, 'FIXME: Currently not working on jython') 
def test_handle_read(self) : 
    class TestClient (BaseClient) : 
        def handle_read(self) : 
            self.flag = True 
class TestHandler (BaseTestHandler) : 
        def __init__(self, conn) : 
            BaseTestHandler.__init__ (self, conn) 
            self.send (('x' * 1024)) 
server = TCPServer (TestHandler) 
    client = TestClient (server.address) 
    self.loop_waiting_for_flag (self)
