Case

sendspin-server-cpp -> sendspin-rs

Start the server first, then the client. The client discovers or looks up the server, initiates the WebSocket connection, advertises PCM as its only supported audio format, streams audio derived from almost_silent.flac, and compares canonical PCM hashes.

Server

sendspin-server-cpp

Client

sendspin-rs

Status

Failed

Server adapter reported: the client sent client/hello but never took the connection with a client/state after server/activate; handshake failed; Client adapter reported: Failed to connect to ws://127.0.0.1:18937/sendspin: Protocol error: unknown variant `server/error`, expected one of `client/hello`, `server/hello`, `client/time`, `server/time`, `client/state`, `server/state`, `server/command`, `client/command`, `stream/start`, `stream/end`, `stream/clear`, `stream/request-format`, `group/update`, `client/goodbye` at line 1 column 22

Server activation

Initial server/activate

What the sendspin-server-cpp server's own adapter recorded for its first server/activate on this connection, reported as sent. The case fails when none was sent, when its activities are not unique values from playback and pairing, or when it omits active_roles. Nothing else in it is checked against the specification: which activities and roles the matched PSK allows is not judged. A recording that cannot be read as that message is shown whole and not judged either.

No server/activate observed

The sendspin-server-cpp server sent no server/activate on this connection, according to its adapter.

Server group state

Every group/update after activation

What the sendspin-server-cpp server's own adapter recorded for each group/update it sent after its first server/activate on this connection, in order and reported as sent. The case fails when none followed, or when in any of them playback_state is not playing or stopped, or group_id or group_name is missing or not a string. How soon the first followed is not judged, because the specification says promptly and gives no bound, so one sent at any point in the case counts. Whether a change to a field produced a further message is not judged either. A recording of anything other than that message is shown whole and fails the case as a harness gap.

No group/update observed after a server/activate

The sendspin-server-cpp server sent no group/update after a first server/activate on this connection, according to its adapter. One sent on a connection that never carried a server/activate is not recorded here.
