Question

我正试图在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脚手架完成更新过程时，它会更新记录，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'

我原以为那些end列会搞砸红宝石，但看起来好像不是......？

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

所以你的断言要求@ new_countdown.name和@ countdown.name是一样的？打开工厂看看，我猜是简单的答案。不确定你要在这里测试什么。

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是否与测试中的查找行中的@countdown相同？

行动有效，但测试没有（Shoulda）
