UnknownServer - Case 5.19 : Fail - 3005 ms @ 2021-02-12T11:15:09.648Z

Case Description

A fragmented text message is sent in multiple frames. After sending the first 2 frames of the text message, a Ping is sent. Then we wait 1s, then we send 2 more text fragments, another Ping and then the final text fragment. Everything is legal.

Case Expectation

The peer immediately answers the first Ping before it has received the last text message fragment. The peer pong's back the Ping's payload exactly, and echo's the payload of the fragmented message back to us.

Case Outcome

Actual events differ from any expected.

Expected:
{'OK': [('pong', u'pongme 1!'), ('pong', u'pongme 2!'), ('message', u'fragment1fragment2fragment3fragment4fragment5', False)]}

Observed:
[('message', u'pongme 1!', False), ('message', u'pongme 2!', False), ('message', u'fragment1fragment2fragment3fragment4fragment5', False)]

Case Closing Behavior

The spec requires the connection to be failed cleanly here (UNCLEAN)

Closing Behavior

KeyValueDescription
isServerFalseTrue, iff I (the fuzzer) am a server, and the peer is a client.
closedByMeTrueTrue, 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.
droppedByMeTrueTrue, 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 did not respond (in time) in 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.
wasCloseHandshakeTimeoutTrueWhen 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).
