我在
ruby.railstutorial.org/ruby-on-rails-tutorial-book上工作.
我使用导轨3.2.7,spork,rspec,capybara,launchy和一些守卫:)
我使用导轨3.2.7,spork,rspec,capybara,launchy和一些守卫:)
在第3章中,我有一个非常奇怪的问题：测试：
似乎测试并不适用于< head> -Tag内的内容.如果我将< title> – 标签放在< body> – 标签内,而不是标题,它可以正常工作.
当我将< h1> – 标签放在< title>在< head> -Tags内.这是奇怪的,不是吗？
请帮我弄清楚.
示例来自：ruby.railstutorial.org/chapters/static-pages#code:title_test：
it "should have the right title" do
visit '/static_pages/home'
page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Home")
end
错误消息是：
Failures:
1) Static pages Home page should have the title ‘Home’
Failure/Error: page.should have_selector(‘title’,:text => ‘ | Home’)
Capybara::ExpectationNotMet:
expected to find css “title” with text ” | Home” but there were no matches. Also found “”,which matched the selector but not all
filters.
# ./spec/requests/static_pages_spec.rb:15:in `block (3 levels) in ‘
那一个正在工作：
it "should have the h1 'Sample App'" do
visit '/static_pages/home'
page.should have_selector('h1',:text => 'Sample App')
end
呈现的HTML文件：
<!DOCTYPE html> <html> <head> <title>Ruby on Rails Tutorial Sample App | Home</title> <!-- some css,js stuff --> </head> <body> <h1>Sample App</h1> <p> This is the home page for the <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> sample application </p> </body> </html>
谢谢

我所做的说明
主页的代码就像它应该是.
关于页面的代码具有自己的布局,在标题标签之上带有h1标签,以显示它的工作原理.
最后,帮助页面的标题标签也在正文标签内.
我绝对困惑,为什么我有这样一个奇怪的行为？

解决方法
我刚刚检查了你在Github上的项目,似乎你正在使用边缘版本的capybara：
的Gemfile
gem 'capybara',:git => 'git://github.com/jnicklas/capybara.git'
Gemfile.lock的
GIT
remote: git://github.com/jnicklas/capybara.git
revision: e561d249555195cdd0e9251246fc75aae876f833
specs:
capybara (2.0.0.beta2)
mime-types (>= 1.16)
nokogiri (>= 1.3.3)
rack (>= 1.0.0)
rack-test (>= 0.5.4)
selenium-webdriver (~> 2.0)
xpath (~> 1.0.0.beta1)
如果没有别的,我敢说这是你问题的原因. (当然,在更新capybara之后,我的reference project全部坏了,使用边缘版本)
因此,除非您热衷于帮助Capybara 2的beta测试,否则您将很乐意遵守here所列的1.1.2版本.
