Question

im new to RoR or rspec and trying to learn it.First of all i cant find tutorials for newbies, just advanced ones, becouse i want to learn RoR and at the same time learn to test. Im writing test for simple CRUD controllers, but i have no idea how to test for example if params passed to my create action, also if it was saved.

def create
    @item = TextItem.new(params[:item])

    if @item.save
       redirect_to(:action =>  index )
    else
       render( new )
      end
  end

Answer 1

我认为,最好的方式是熟悉铁路和风 rub,只有这样,它们才会被拖进/带上测试/unit或微型测试或rs、 cu或许多其他试验技术。

我建议你购买一本书/书,以开始,例如,这一书。铁路的发展只有24美元。你将节省很多时间。

有时Rspec是一种微薄的trick/魔法,没有铁路/铁路的基本知识,可能难以开始使用。

我不建议你在一次尝试中研究铁路和铁路。

BTW对这一行动的期望可能如下:

  describe "POST create" do
    let(:item) { mock_model(TextItem) }

    before(:each) do
      TextItem.stub(:new).and_return(item)
    end

    it "saves the item" do
      item.should_receive(:save)
      post :create
    end

    context "when the item saves successfully" do
      before(:each) do
        item.stub(:save).and_return(true)
      end

      it "redirects to the items index" do
        post :create
        response.should redirect_to(:action => "index")
      end
    end

    context "when the item fails to save" do
      before(:each) do
        item.stub(:save).and_return(false)
        item.stub_chain(:errors, :empty?).and_return(false)
      end

      it "renders the new template" do
        post :create
        response.should render_template(:new)
      end
    end
  end
