Hello, I think I have found a bug in the mentioned test. The test verifies that NodeA does not receive any message whose origin is peerA, but when the test defines msgRecN1 with the 'streamIncomingGossips' function, a Callback is defined. In the project specification it is stated that every time a peer receives a new message(from another gossiper or from the client), it must call the callback. But in the second case the rumor message will have as origin the node itself, making the test fail. I don't know if I am wrong, please let me know.
