Case
sendspin-server-cpp -> sendspin-js
Start the server first, then the client. The client discovers or looks up the server and initiates the WebSocket connection, the server observes controller state, receives a control command, disconnects, and the matrix verifies the recorded command.
Server
sendspin-server-cpp
Client
sendspin-js
Status
Failed
Server adapter reported: the client sent client/hello but never took the connection with a client/state after server/activate; handshake failed
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.
