wsgo fuzzing client - Case 3.4 : Non-Strict - 1 ms @ 2025-03-31T15:46:19.605Z
Case Description
Send small text message, then send again with RSV = 4, then send Ping. Octets are sent in octet-wise chops.
Case Expectation
Echo for first message is received, but then connection is failed immediately, since RSV must be 0, when no extension defining RSV meaning has been negotiated. The Pong is not received.
Case Outcome
Actual events match at least one expected.
Expected:
{'OK': [('message', u'Hello, world!', False)], 'NON-STRICT': []}
Observed:
[]
Case Closing Behavior
It is preferred that the server close the TCP connection (FAILED BY CLIENT)

| Key | Value | Description |
| isServer | False | True, iff I (the fuzzer) am a server, and the peer is a client. |
| closedByMe | False | 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 | True | True, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility). |
| wasNotCleanReason | None | 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). |
