Case Description

Send a text message with payload which is not valid UTF-8 in one fragment.

Payload: 0x808182838485868788898a8b8c8d8e8f909192939495969798999a9b9c9d9e9fa0a1a2a3a4a5a6a7a8a9aaabacadaeafb0b1b2b3b4b5b6b7b8b9babbbcbdbe

Case Expectation

The connection is failed immediately, since the payload is not valid UTF-8.

Case Outcome

Expected:
{'OK': []}

Observed:
[('message', '0xefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdefbfbdef ...', False)]

013 TCP DROPPED BY PEER

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	True	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	True	True, iff full WebSockets closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility).
wasNotCleanReason	None	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	1001	The close code I sent in close frame (if any).
localCloseReason	Going Away	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).
