Question

在尝试完成Hartl轨道教程的第5章练习3后，我收到以下RSpec错误：

1) Static pages should have the right links on the layout
 Failure/Error: click_link "Sign up now!"
 Capybara::ElementNotFound:
   Unable to find link "Sign up now!"
 # ./spec/requests/static_pages_spec.rb:56:in `block (2 levels) in <top (required)>'

似乎无法在按钮上找到立即注册链接。

以下是我的spec / requests / static_pages_spec.rb文件中的相关部分：

it "should have the right links on the layout" do
    visit root_path
    click_link "About"
    expect(page).to have_title(full_title('About Us'))
    click_link "Help"
    expect(page).to have_title(full_title('Help'))
    click_link "Contact"
    expect(page).to have_title(full_title('Contact'))
    click_link "Sign up now!"
    expect(page).to have_title(full_title('Sign Up'))
    click_link "Home"
    expect(page).to have_content('Sample')
    click_link "sample app"
    expect(page).to have_content('Sample')
end

询问点击注册链接的页面是否具有页面标题“注册”。但它甚至找不到“立即注册！”链接，如上面的错误所示。这里是app / views / static_pages / home.html.erb的主页，以表明它确实有“立即注册！”链接（作为一个按钮，但我已尝试click_button也没有成功）：

 <div class="center hero-unit">
  <h1>Welcome to the Sample App</h1>

<h2>
  This is the home page for the
  <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
  sample application.
</h2>

<%= link_to "Sign up now!", signup_path , class: "btn btn-large btn-primary" %>
</div>

所以我不确定为什么它找不到“立即注册！”当它以这种方式清晰地格式化时链接。当我在本地运行rails服务器时，它显然有该链接。感谢您提供任何指导。

这是注册页面，位于app / views / users / new.html.erb，只是为了覆盖我的基础。正如您所看到的，它确实使页面标题为“注册”：

<% provide(:title, 'Sign Up') %>
<h1>Sign up</h1>
<p>Find me in app/views/users/new.html.erb</p>

最后，这是我的路线，也是我的基地。如您所见，它确实路由到新用户：

SampleApp::Application.routes.draw do
  get "users/new"
  root 'static_pages#home'
  match '/help', to: 'static_pages#help', via: 'get'
  match '/about', to: 'static_pages#about', via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'
  match '/signup', to: 'users#new', via: 'get'
  .
  .
  .
end

如果它可能是gemfile错误，这是我的gemfile：

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.8'
gem 'bootstrap-sass', '2.3.2.0'

end

end

end

Answer 1

单击链接后，无头浏览器Capybara会导航到该页面。因此，当您在测试中单击Sign up now!时，无头浏览器位于“联系”页面，而不是主页。

在您尝试点击＆＃34之前指定visit root_path;立即注册！＆＃34;链接应该工作。

您可以在尝试点击＆＃34;立即注册之前插入click_link 'Home'！＆＃34;。

另一种可能是结构更好的解决方案是对每个链接进行测试：

describe "layout" do

    before(:each) do
        visit root_path
    end

    it "should have About link" do
        click_link 'About'
        expect(page).to have_title(full_title('About Us'))
    end

    it "should have Help link" do
        click_link 'Help'
        expect(page).to have_title(full_title('Help'))
    end

    it "should have Sign Up link" do
        click_link "Sign up now!"
        expect(page).to have_title(full_title('Sign Up'))
    end


    (...)

end

祝你好运！
