Closing Behavior

Key	Value	Description
isServer	False	True, iff I (the fuzzer) am a server, and the peer is a client.
closedByMe	True	True, iff I have initiated closing handshake (that is, did send close first).
failedByMe	False	True, iff I have failed the WS connection (i.e. due to protocol error). Failing can be either by initiating closing handshake or brutal drop TCP.
droppedByMe	False	True, iff I dropped the TCP connection.
wasClean	False	True, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility).
wasNotCleanReason	peer dropped the TCP connection without previous WebSocket closing handshake	When wasClean == False, the reason what happened.
wasServerConnectionDropTimeout	False	When we are a client, and we expected the server to drop the TCP, but that didn't happen in time, this gets True.
wasOpenHandshakeTimeout	False	When performing the opening handshake, but the peer did not finish in time, this gets True.
wasCloseHandshakeTimeout	False	When we initiated a closing handshake, but the peer did not respond in time, this gets True.
localCloseCode	1000	The close code I sent in close frame (if any).
localCloseReason	None	The close reason I sent in close frame (if any).
remoteCloseCode	None	The close code the peer sent me in close frame (if any).
remoteCloseReason	None	The close reason the peer sent me in close frame (if any).
