describe "Application Connections", :connection do
  it "connects with proper cookie" do
    # Simulate the connection request with a cookie.
    cookies["user_id"] = users(:john).id

    connect

    # Assert the connection identifier matches the fixture.
    value(connection.user.id).must_equal users(:john).id
  end

  it "rejects connection without proper cookie" do
    must_reject_connection { connect }
  end
end
