Overview

In-memory Socket implementation for specs and local prototyping. Captures every frame the client sends in ‘sent_frames`, and exposes `inject(frame)` so a test can simulate a server response.

Not intended for production use — bring a real WebSocket adapter for that.

#inject(frame) ⇒ Object

Push a JSON frame as if it came from the server. Accepts a JSON String or a Hash (which gets JSON-encoded for you).

def inject(frame)
  raw = frame.is_a?(String) ? frame : JSON.generate(frame)
  message_callbacks.each { |cb| cb.call(raw) }
end

#last_sent_frame ⇒ Object

Convenience: the last frame the client pushed, parsed back to a Hash.
