Multiple chat rooms are created by just sending "test" as a message (xmpp->matrix). One of them will have the message sent, the rest will be empty rooms. When the matrix user joins & sends any message it will be "echoed" back as sent by the xmpp user, while the xmpp messages won't be received. Any messages sent by the xmpp user will be sent in a new room.

Tests done using a matrix.org account.
