哈特尔回报率教程第5章练习1：失败的测试：it_should_behave_like和should_not have_title

Question

我在与哈特尔的回报率教程第5章练习1.

的行使设置了测试规范的问题。在下面的测试规范中给出。

当我运行“bundle exec rspec spec/”时，出现ERROR下面给出的错误。

如果我注释掉两个：

it_should_behave_like "all static pages" 
it { should_not have_title('| Home') } 

测试通过...

问：这有什么错it_should_behave_like和should_not have_title

**ERROR**

    it { should have_title(full_title(page_title)) } 
    end 

    describe "Home page" do 
    before { visit root_path } 
    let(:heading) { 'Sample App' } 
    let(:page_title) { '' } 

    it_should_behave_like "all static pages" 
    it { should_not have_title('| Home') } 
    end

尝试更新水豚到2.1版。 0在你的Gemfile中。 have_title是新的选择器之一。
