RubyTutorial 10.5.2 Rspec测试微博分页

Question

在阅读Michael Hartl撰写的Learn Rails书时,我对其中一个练习感到困惑. 通过Michael Hartl的例子学习Rails

"添加微博分页测试"

我的错误测试,放在登录用户"do"的'describe'中,如下所示:

describe "pagination" do
    before(:all) do 
      30.times { FactoryGirl.create(:micropost, user: user) }
    end
    after(:all) { user.feed.delete_all }
    page.should have_selector('div.pagination') }

    it "should list each micropost" do
      user.feed.paginate(page: 1).each do |user|
        page.should have_selector('li', text: user.name)
      end
    end
  end 

无论我是做page.should还是page.should_not,测试都会显示为pass.

任何'提示/帮助'将不胜感激

在浏览一些repos时,我找到了我的问题的答案 - 我需要在创建额外的微博后再次访问root_path.

describe "pagination" do
  it "should paginate the feed" do
    30.times { FactoryGirl.create(:micropost, user: user, content: "Consectetur adipiscing elit") }
    visit root_path
    page.should have_selector("div.pagination")
  end
end
