websock secure server - Case 5.6 : Pass - 1 ms @ 2025-11-26T12:36:17.101Z

Case Description

Send text Message fragmented into 2 fragments, one ping with payload in-between.

Case Expectation

A pong is received, then the message is echo'ed back to us.

Case Outcome

Actual events match at least one expected.

Expected:
{'OK': [('pong', u'ping payload'), ('message', u'fragment1fragment2', False)]}

Observed:
[('pong', u'ping payload'), ('message', u'fragment1fragment2', False)]

Case Closing Behavior

The spec requires the connection to be failed cleanly here (UNCLEAN)

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.
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.
localCloseCode1000The close code I sent in close frame (if any).
localCloseReasonNoneThe 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).
