当预期输出正确时,Rspec has_selector错误

Car*_*yes 1 ruby-on-rails capybara rspec-rails railstutorial.org

我有3个rspec选择器失败时,他们都应该成功.我跟随rails-tutorial.org书和他的节目一样正确.

PagesController GET 'home' should have the right title
     Failure/Error: response.should have_selector("title", :content => "Ruby on Rails     Sample App | Home")
       expected following output to contain a <title>Ruby on Rails Sample App | Home</title> tag:
   <!DOCTYPE html>
   <html>
   <head>
   <meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
   <title>Ruby on Rails Tutorial Sample App | Home</title>
   </head>

如果您正在使用Capybara 2.0,title则忽略该元素之类的隐形文本.请参阅Capybara Github有关它的问题.

Rails教程专门使用Capybara版本1.1.2,因此如果您还没有这样做,请确保根据教程Gemfile为您的所有宝石编写显式版本.

如果您想现在或将来使用Capybara 2.0,请参阅以下SO问题以获得帮助进行设置,以及让title元素再次进行测试:
