尝试测试该页面包含<title>My Title</title>
:
# spec/features/reports_spec.rb
require 'spec_helper'
feature "Archive Management" do
subject { page }
describe "Index Page" do
before(:all) { 10.times { FactoryGirl.create(:randomreport) } }
after(:all) { Report.delete_all }
describe "when no search terms present" do
before { visit reports_path }
it { should have_selector('title', text: 'My Title') } # <= Fails w/Capybara 2.0
it { should have_selector('title') } # <= passes
it { should have_text('My Title') } # <= passes
it { should have_selector('h2', text: "Welcome") } # <= passes
end
end
end
错误信息:
Failure/Error: it { should have_selector('title', text: base_title) }
Capybara::ExpectationNotMet:
expected to find css "title" with text "My Title" but there were no matches. Also found "", which matched the selector but not all filters.
我知道我忽略了痛苦的显而易见但无法弄清楚它是什么?<title>
标签不再被视为“选择器”吗?!?或者...?!?
编辑(调试器信息):
如果我按照@shioyama 的巧妙建议下拉到调试器中,很明显 page.body 包含<title>My Title</title>
. 包含<h2>Welcome to My Title Project</h2>
和传递的同一个 page.body!
它似乎找到了<title>
...</title>
标签,但不在My Title
其中。但它确实My Title
稍后会在页面内<a href=\"/\" class=\"brand\">My Title</a>
和/或内找到<h2>Welcome to The My Title Project</h2>
:
(rdb:1) p page
#<Capybara::Session>
(rdb:1) p page.body
"<!DOCTYPE html>\n<html>\n<head>\n<title>My Title</title>\n
<meta content='research, report, technology' name='keywords'>\n<meta
content='Some Project' name='description'>\n<link href=\"/assets/application.css\"
...
</head>\n<body>\n<header class='navbar navbar-fixed-top
navbar-inverse'>\n<div class='navbar-inner'>\n<div class='container'>\n
<a href=\"/\" class=\"brand\">My Title</a>\n<div class='pull-right'>\n
<ul class='nav'>\n<li><a href=\"/about\">About</a></li>\n<li><a href=\"/help\">Help</a>

<input class=\"search-query\" id=\"query\" name=\"query\"

<div class='container'>\n<div class='hero-unit center'>\n<h1>My Title</h1>\n
<h2>Welcome to The My Title Project</h2>\n<p>Lorem ipsum dolor sit amet, consectetur

...
我还能在调试器中尝试什么来找出为什么 have_selector?('title', text: ...) 失败了?
那么,在 Capybara 2.0 中测试标题的正确方法是什么?
