wsgo fuzzing client - Case 6.2.4 : Fail - 1002 ms @ 2025-03-31T15:47:10.763Z
Case Description
Send a valid UTF-8 text message in fragments of 1 octet, resulting in frames ending on positions which are not code point ends.
MESSAGE:
κόσμε
cebae1bdb9cf83cebcceb5
Case Expectation
The message is echo'ed back to us.
Case Outcome
Actual events differ from any expected.
Expected:
{'OK': [('message', u'\u03ba\u1f79\u03c3\u03bc\u03b5', False)]}
Observed:
[]
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 | True | 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 | True | 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 did not respond (in time) in 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 | True | When we initiated a closing handshake, but the peer did not respond in time, this gets True. |
| localCloseCode | 1007 | The close code I sent in close frame (if any). |
| localCloseReason | UTF-8 text message payload ended within Unicode code point at payload octet index 1 | 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). |
