问题描述
我从本书中进行了这项测试：
I have this test from michael hartl book:
require 'spec_helper'
describe "Static pages" do
let(:base_title) { "Ruby on Rails Tutorial Sample App" }
describe "Home page" do
it "should have the h1 'Sample App'" do
visit '/static_pages/home'
page.should have_selector('h1', :text => 'Sample App')
end
it "should have the title 'Home'" do
visit '/static_pages/home'
page.should have_selector('title', :text => "#{base_title} | Home")
end
end
end
视图：
<% provide(:title, 'Home') %>
<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>
我运行测试时说：
....
Finished in 1.91 seconds
4 examples, 0 failures
Randomized with seed 42247
.F...
Failures:
1) Static pages Home page should have the title 'Home'
Failure/Error: page.should have_selector('title', :text => "#{base_title} | Home")
expected #has_selector?("title", {:text=>"Ruby on Rails Tutorial Sample App | Home"}) to return true, got false
# ./spec/requests/static_pages_spec.rb:16:in `block (3 levels) in <top (required)>'
Finished in 1.91 seconds
5 examples, 1 failure
Failed examples:
rspec ./spec/requests/static_pages_spec.rb:14 # Static pages Home page should have the title 'Home'
Randomized with seed 17491
但是它应该通过，因为当我在浏览器中查看页面时，标题是：Ruby on Rails Tutorial Sam ple App |
But It should pass, because when I view the page in browser the title is: Ruby on Rails Tutorial Sample App | Sample App, which is correct!
推荐答案
请确保您在Gemfile中使用了水豚1.1.2。从2.0开始，capybara不适用于标题测试（https://github.com/jnicklas/capybara/issues/844）
Make sure you're using capybara 1.1.2 in your Gemfile. Starting from 2.0 capybara does not works for title testing (https://github.com/jnicklas/capybara/issues/844)
...
group :test do
gem 'capybara', '1.1.2'
end
