web-sct 0.2.0 - Case 6.4.1 : Non-Strict - 2010 ms @ 2021-01-18T16:56:06.138Z

Case Description

Send invalid UTF-8 text message in 3 fragments (frames). First frame payload is valid, then wait, then 2nd frame which contains the payload making the sequence invalid, then wait, then 3rd frame with rest. Note that PART1 and PART3 are valid UTF-8 in themselves, PART2 is a 0x110000 encoded as in the UTF-8 integer encoding scheme, but the codepoint is invalid (out of range).

MESSAGE PARTS:
PART1 = cebae1bdb9cf83cebcceb5
PART2 = f4908080
PART3 = 656469746564

Case Expectation

The first frame is accepted, we expect to timeout on the first wait. The 2nd frame should be rejected immediately (fail fast on UTF-8). If we timeout, we expect the connection is failed at least then, since the complete message payload is not valid UTF-8.

Case Outcome

Actual events match at least one expected.

Expected:
{'OK': [('timeout', 'A')], 'NON-STRICT': [('timeout', 'A'), ('timeout', 'B')]}

Observed:
[('timeout', 'A'), ('timeout', 'B')]

Case Closing Behavior

Connection was properly closed (OK)

Closing Behavior

KeyValueDescription
isServerFalseTrue, iff I (the fuzzer) am a server, and the peer is a client.
closedByMeFalseTrue, iff I have initiated closing handshake (that is, did send close first).
failedByMeFalseTrue, 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.
droppedByMeFalseTrue, iff I dropped the TCP connection.
wasCleanFalseTrue, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility).
wasNotCleanReasonpeer dropped the TCP connection without previous WebSocket closing handshakeWhen wasClean == False, the reason what happened.
wasServerConnectionDropTimeoutFalseWhen we are a client, and we expected the server to drop the TCP, but that didn't happen in time, this gets True.
wasOpenHandshakeTimeoutFalseWhen performing the opening handshake, but the peer did not finish in time, this gets True.
wasCloseHandshakeTimeoutFalseWhen we initiated a closing handshake, but the peer did not respond in time, this gets True.
localCloseCodeNoneThe close code I sent in close frame (if any).
localCloseReasonNoneThe close reason I sent in close frame (if any).
remoteCloseCodeNoneThe close code the peer sent me in close frame (if any).
remoteCloseReasonNoneThe close reason the peer sent me in close frame (if any).
