Case Description
Send invalid UTF-8 text message in fragments of 1 octet, resulting in frames ending on positions which are not code point ends.
MESSAGE:
cebae1bdb9cf83cebcceb5eda080656469746564
Case Expectation
The connection is failed immediately, since the payload is not valid UTF-8.
Case Outcome
Actual events match at least one expected.
Expected:
{'OK': []}
Observed:
[]
Case Closing Behavior
Connection was properly closed (OK)

| 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 | 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 | 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 | 1007 | The close code the peer sent me in close frame (if any). |
| remoteCloseReason | payload must be valid UTF-8 | The close reason the peer sent me in close frame (if any). |
