如何向控制台显示页面内容（DOM）？

Question

请帮助解决问题。 我使用rspec +水豚+撬。

测试：

it 'check albums page' do
  user = FactoryGirl.create(:user)  
  visit user_albums_path(user.id)      
  expect(response.status).to eq(200)      
  expect(response).to render_template(:index)
  expect(page).to have_selector(".albums_list_label")     
end 

结果：

Failures:
  1) AlbumsController index action check albums page
     Failure/Error: expect(page).to have_selector(".albums_list_label")
       expected to find css ".albums_list_label" but there were no matches
     # ./spec/controllers/albums_controller_spec.rb:18:in `block (3 levels) in <top (required)>'

我需要显示页面内容（DOM）。 我尝试使用宝石“撬”：

it 'check albums page' do
  user = FactoryGirl.create(:user)  
  visit user_albums_path(user.id)      
  expect(response.status).to eq(200)      
  expect(response).to render_template(:index)
  binding.pry
  expect(page).to have_selector(".albums_list_label")     
end   

结果我在控制台中进入调试模式：

    12:     it 'check albums page' do
    13:       user = FactoryGirl.create(:user)  
    14:       visit user_albums_path(user.id)      
    15:       expect(response.status).to eq(200)      
    16:       expect(response).to render_template(:index)
 => 17:       binding.pry
    18:       expect(page).to have_selector(".albums_list_label")     
    19:     end      
    20: 

[1] pry(#<RSpec::ExampleGroups::AlbumsController::IndexAction>)>

但我不知道如何将DOM输出到控制台
