Action有效，但test无效(Shoulda)

Question

我尝试用下面的代码在Rails中测试我的更新操作：

context "on PUT to :update" do
  setup do
    @countdown = Factory(:countdown)
    @new_countdown = Factory.stub(:countdown)
    put :update, :id => @countdown.id, :name => @new_countdown.name, :end => @new_countdown.end
  end

  should_respond_with :redirect
  should_redirect_to("the countdowns view") { countdown_url(assigns(:countdown)) }
  should_assign_to :countdown
  should_set_the_flash_to /updated/i

  should "save :countdown with new attributes" do
    @countdown = Countdown.find(@countdown.id)
    assert_equal @new_countdown.name, @countdown.name
    assert_equal 0, (@new_countdown.end - @countdown.end).to_i
  end    
end

当我实际使用构建的scaffold完成更新过程时，它可以很好地更新记录，但测试给出了这个错误：

  1) Failure:
test: on PUT to :update should save :countdown with new attributes. (CountdownsControllerTest)

Answer 1

我本以为那些end专栏会搞砸ruby，但看起来并没有...？

不管怎样，我假设/test/functional/countdowns_controller_test.rb:86就是这个断言：assert_equal @new_countdown.name, @countdown.name。

所以你的断言是问@new_countdown.name和@countdown.name是一样的吗？打开工厂看看，我想这是个简单的答案。不确定您在这里尝试测试的是什么。

另外，为什么@countdown = Countdown.find(@countdown.id)使用相同的实例变量名？设置中的@countdown与测试中find行中的@countdown不是相同的吗？
