ruby-on-rails-3.2 - 未定义的局部变量或方法“页面”

Question

我正在使用导轨。我使用以下命令执行 ruby​​ 脚本。它给出了一个错误。会有什么问题？如果我删除“page.should have_content('Demo App')”，那么它可以正常工作！

 bundle exec rspec spec/requests/test_pages_spec.rb

Failed examples:

rspec ./spec/requests/test_pages_spec.rb:7 # Test pages Home page should have the content 'Demo App'

test_pages_spec.rb 如下：

require 'spec_helper'

describe "Test pages" do

describe "Home page" do

   it "should have the content 'Demo App'" do
    visit '/test_pages/home'
    page.should have_content('Demo App')
   end
 end
end

我已经解决了这个问题。如果我同时使用 webrat 和 capybara，那么我看不到正确的结果。所以我必须从 Gemfile 中删除gem 'webrat'并输入bundle update并使用以下命令，问题就解决了！

bundle exec rspec spec/requests/test_pages_spec.rb
