即使使用 config.render_views，RSpec response.body 仍然是空的 [英] RSpec response.body is still empty even with config.render_views

问题描述

在我的 spec_helper.rb 文件中，我专门将它设置为 config.render_views 但我返回的 response.body 仍然是空的.这是我的基本规格

In my spec_helper.rb file I have specifically set it to config.render_views but the response.body I get back is still empty. Here is my basic spec

describe  "#index" do
    it "should list all rooms" do
      get 'index'
      stub(Person).all
    end

    it "responds with 200 response code" do
      response.should be_ok
    end

    it "renders the index template" do
      pp response.body
      response.should render_template("people/index")
    end

  end

还有什么可以缩短这种行为的吗?当我通过浏览器时，这很好.我使用的是 Rspec 2.5.0

Is there anything else that could have shorted this behavior? It's fine when I go through the browser. I am on Rspec 2.5.0

推荐答案

您是否尝试过在控制器规范文件中包含 render_views?这对我有用.

Have you tried having render_views in your controller spec file? That works for me.

我注意到的另一件事是，您在测试用例中只能访问索引页面一次 - 准确地说是第一个.其余的将返回空的html内容，因为没有响应.

Another thing I noticed is that you only access the index page once in your test cases - the first one to be precise. The rest will return empty html content because there is no response.

这就是我将如何实现它.但是如果您在 *spec_helper.rb* 文件中已经有 config.render_views 并且有效，那么您可以在控制器规范中没有 render_views .

This is how I will implement it. But if you already have config.render_views in the *spec_helper.rb* file and that works, you can do without the render_views in the controller spec.

describe MyController
    render_views

    before :each do
        get :index
    end

    describe  "#index" do
        it "should list all rooms" do
            stub(Person).all
        end

        it "responds with 200 response code" do
            response.should be_ok
        end

        it "renders the index template" do
            pp response.body
            response.should render_template("people/index")
        end
    end
end

这里的细微变化是 before 块，我在其中为每个 it 块调用 get :index.

The subtle change here is the before blobk in which I call get :index for every it block.
