websock server - Case 2.10 : Pass - 3 ms @ 2026-04-11T02:41:00.225Z
Case Description
Send 10 Pings with payload.
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)

| 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 | False | 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 | False | True, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility). |
| wasNotCleanReason | peer dropped the TCP connection without previous WebSocket closing handshake | 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 | 1000 | The close code I sent in close frame (if any). |
| localCloseReason | None | 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). |
