stratus@2 - Case 3.2 : Fail - 1001 ms @ 2026-04-02T15:17:18.866Z

Case Description

Send small text message, then send again with RSV = 2, then send Ping.

Case Expectation

Echo for first message is received, but then connection is failed immediately, since RSV must be 0, when no extension defining RSV meaning has been negotiated. The Pong is not received.

Case Outcome

Actual events differ from any expected.

Expected:
{'OK': [('message', u'Hello, world!', False)], 'NON-STRICT': []}

Observed:
[('message', u'Hello, world!', False), ('message', u'Hello, world!', False), ('pong', u'')]

Case Closing Behavior

The connection was failed by the wrong endpoint (FAILED)

Closing Behavior

KeyValueDescription
isServerTrueTrue, iff I (the fuzzer) am a server, and the peer is a client.
closedByMeTrueTrue, iff I have initiated closing handshake (that is, did send close first).
failedByMeTrueTrue, 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.
droppedByMeFalseTrue, iff I dropped the TCP connection.
wasCleanFalseTrue, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility).
wasNotCleanReasonpeer dropped the TCP connection without previous WebSocket closing handshakeWhen wasClean == False, the reason what happened.
wasServerConnectionDropTimeoutFalseWhen we are a client, and we expected the server to drop the TCP, but that didn't happen in time, this gets True.
wasOpenHandshakeTimeoutFalseWhen performing the opening handshake, but the peer did not finish in time, this gets True.
wasCloseHandshakeTimeoutFalseWhen we initiated a closing handshake, but the peer did not respond in time, this gets True.
localCloseCode1001The close code I sent in close frame (if any).
localCloseReasonGoing AwayThe close reason I sent in close frame (if any).
remoteCloseCodeNoneThe close code the peer sent me in close frame (if any).
remoteCloseReasonNoneThe close reason the peer sent me in close frame (if any).
