Fixture store provides REST-ful resource storage. Its designed to work with XHR requests thus its methods expect two arguments request and response. To work with socket events we need to transform request handlers into socket event listeners.

Here is how we can do this:

var fixture = require("can-fixture");
var canSet = require("can-set");
var io = require("socket.io-client");
var fixtureSocket = require("can-fixture-socket");

// Create fixture store:
var fixtureStore = fixture.store([
  {id: 1, title: 'One'},
  {id: 2, title: 'Two'},
  {id: 3, title: 'Three'}
], new canSet.Algebra({}));

// Instantiate mocked socket server:
var mockedServer = new fixtureSocket.Server(io);

// Now use fixture store to emulate REST-ful service:
var toListener = fixtureStore.requestHandlerToListener;
mockedServer.on({
  "books find":   toListener( fixtureStore.getListData ),
  "books get":    toListener( fixtureStore.getData ),
  "books create": toListener( fixtureStore.createData ),
  "books update": toListener( fixtureStore.updateData ),
  "books delete": toListener( fixtureStore.destroyData )
});
