### Question:
MessageEnvelope implements Message { public String getContent() { return content; } MessageEnvelope(NodeHandle sendingNode, String content);  MessageEnvelope(NodeHandle sendingNode, i5.las2peer.communication.Message content); NodeHandle getSendingNode(); String getContent(); i5.las2peer.communication.Message getContainedMessage(); @Override int getPriority();  }### Answer:
@Test public void testSimpleContent() { try { String data = "some data to test"; MessageEnvelope testee = new MessageEnvelope(null, data); byte[] serialized = SerializeTools.serialize(testee); MessageEnvelope andBack = (MessageEnvelope) SerializeTools.deserialize(serialized); assertEquals(data, andBack.getContent()); } catch (Exception e) { e.printStackTrace(); Assert.fail(e.toString()); } }
