Question

以下是spec / controllers / movies_controller_spec.rb中我的rspec代码的一部分：

it 'should call a controller method to receive the click on
"Find With Same Director", and grab the id of the subject' do     
  Movie.stub('find_similar_movies')
  controller.should_receive('similar_movies').
          with(hash_including :id => '3')
  visit movie_path('3')
  click_link('Find Movies With Same Director')
end

我总是得到错误：

Failure/Error: click_link('Find Movies With Same Director')
     Capybara::ElementNotFound:
       Unable to find link "Find Movies With Same Director"

以下是我在app / views / movies / show.html.haml中的观点的一部分：

%h2 Details about #{@movie.title}

%ul#details
  %li
    Rating:
    = @movie.rating
  %li
    Director:
    = @movie.director
  %li
    Released on:
    = @movie.release_date.strftime("%B %d, %Y")

%h3 Description:

%p#description= @movie.description

= link_to 'Edit', edit_movie_path(@movie)
= button_to 'Delete', movie_path(@movie), :method => :delete, :confirm => 'Are you sure?' 
= link_to 'Back to movie list', movies_path
= link_to 'Find Movies With Same Director', similar_movies_path(@movie)

我也用同样的步骤运行黄瓜：访问同一页面，然后点击链接，它就通过了。但是在rspec中，我没有通过测试。

默认情况下，视图不会在RSpec控制器测试中呈现，因此您的Capybara find_link方法正在查看空白并且无法成功。

您可以通过在render_views块顶部describe调用{{1}}来“打开”示例组的视图呈现，如https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs/render-views

中所述

但是，控制器应使用其他机制进行测试，如https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs

中所述

无法在rspec中找到链接
