websock secure server - Case 1.2.8 : Pass - 25 ms @ 2026-04-11T02:41:19.737Z

Case Description

Send binary message message with payload of length 65536. Sent out data in chops of 997 octets.

Case Expectation

Receive echo'ed binary message (with payload as sent). Clean close with normal code.

Case Outcome

Actual events match at least one expected.

Expected:
{'OK': [('message', '0xfefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefe ...', True)]}

Observed:
[('message', '0xfefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefefe ...', True)]

Closing Behavior

KeyValueDescription
isServerFalseTrue, 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).
failedByMeFalseTrue, 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.
wasCleanTrueTrue, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility).
wasNotCleanReasonNoneWhen 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.
localCloseCode1000The close code I sent in close frame (if any).
localCloseReasonNoneThe close reason I sent in close frame (if any).
remoteCloseCode1000The close code the peer sent me in close frame (if any).
remoteCloseReasonNoneThe close reason the peer sent me in close frame (if any).
