websock-client - Case 2.11 : Pass - 18 ms @ 2026-01-07T13:35:15.295Z

Case Description

Send 10 Pings with payload. Send out octets in octet-wise chops.

Case Expectation

Pongs for our Pings with all the payloads. Note: This is not required by the Spec .. but we check for this behaviour anyway. Clean close with normal code.

Case Outcome

Actual events match at least one expected.

Expected:
{'OK': [('pong', u'payload-0'), ('pong', u'payload-1'), ('pong', u'payload-2'), ('pong', u'payload-3'), ('pong', u'payload-4'), ('pong', u'payload-5'), ('pong', u'payload-6'), ('pong', u'payload-7'), ('pong', u'payload-8'), ('pong', u'payload-9')]}

Observed:
[('pong', u'payload-0'), ('pong', u'payload-1'), ('pong', u'payload-2'), ('pong', u'payload-3'), ('pong', u'payload-4'), ('pong', u'payload-5'), ('pong', u'payload-6'), ('pong', u'payload-7'), ('pong', u'payload-8'), ('pong', u'payload-9')]

Case Closing Behavior

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

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).
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).
