ruby-on-rails - 行动有效，但测试无效(应该)

Question

我正在尝试用这个测试我在 Rails 中的更新操作:

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脚手架完成更新过程时，它会很好地更新记录，但测试会给我这个错误:

  1) Failure:
test: on PUT to :update should save :countdown with new attributes. (CountdownsControllerTest)
[/test/functional/countdowns_controller_test.rb:86:in `__bind_1276353837_121269'

我会想到那些end专栏会搞砸 ruby ，但看起来它可能不会......？

无论如何，所以我假设/test/functional/countdowns_controller_test.rb:86这个断言是:assert_equal @new_countdown.name, @countdown.name .

所以您的断言是在询问@new_countdown.name 和@countdown.name 是否相同？打开工厂看看，我想这是简单的答案。不确定您要在这里测试什么。

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 是否与测试中查找行中的@countdown 相同？
