websock-client - Case 5.20 : Pass - 1002 ms @ 2025-11-26T12:36:06.467Z
Case Description
Same as Case 5.19, but send all frames with SYNC = True.
Note, this does not change the octets sent in any way, only how the stream
is chopped up on the wire.
Case Expectation
Same as Case 5.19. Implementations must be agnostic to how
octet stream is chopped up on wire (must be TCP clean).
Case Outcome
Actual events match at least one expected.
Expected:
{'OK': [('pong', u'pongme 1!'), ('pong', u'pongme 2!'), ('message', u'fragment1fragment2fragment3fragment4fragment5', False)]}
Observed:
[('pong', u'pongme 1!'), ('pong', u'pongme 2!'), ('message', u'fragment1fragment2fragment3fragment4fragment5', False)]
Case Closing Behavior
The spec requires the connection to be failed cleanly here (UNCLEAN)

| Key | Value | Description |
| isServer | True | 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). |
