在Rails Testing中为assert_redirected_to

context \"non-empty Customer model\" do
  setup do
    @customer = Customer.first || Customer.create(:name => \"John\", :address => \"123 Street Cool\", :telephone => \"01484349361\", :email => \"johnsmith@world.com\")
  end

  should \"be able to create\" do
    get \"/customers/new\"
    assert_response :success
    post \"/customers/create\", :post => @customer
    # assert_response :success
    assert_redirected_to \"/customers/list\"
  end

  def new
    @customer = Customer.new

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @customer }
    end
  end

  def create
    # Instantiate a new object using form params
    @customer = Customer.new(params[:customer])
    # Save the object
    if @customer.save
      # If save succeeds, redirect to the list action
      flash[:notice] = \"Customer created.\"
      redirect_to(:action => \'list\')
    else
      # If save fails, redisplay the form so user can fix problems
      render(\'new\')
    end
  end
