RSpec have_tag failing even when tag is present?
Currently doing the Ruby On Rails Tutorial by Michael Hartl, and am starting on test-driven development. The tutorial demands that tests be written to ensure that the right titles are present on our html.erb pages. There are three of these pages - home, contact and about. The tests look like so:
it "should have the right title" do
get 'home'
response.should have_tag("title",
"Ruby On Rails Sample Application | Home")
end
My home.html.erb file looks like so:
&l开发者_JS百科t;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Ruby On Rails Sample Application | Home</title>
</head>
<body>
<h1>Sample App Home</h1>
<p>This is the home page for the
<a href="http://www.railstutorial.org/">Ruby on Rails Tutorial</a>
sample application.</p>
</body>
</html>
As you can see, the title tag is present and it's wrapping the correct text. However, when I run my test, I get this error message:
'PagesController GET 'home' should have the right title' FAILED
Expected at least 1 element matching "title", found 0.
Can anyone explain what is going wrong here? Thanks
Do you have
require 'spec_helper'
on top of your pages_controller_spec.rb?
Do you have
render_views
statement in your describe block?
To John Paul Ashenfelter, I thought save_and_open_page was Capybara method, and not Rspec?
You should start by making sure the page renders correctly using
save_and_open_page
in your Rspec. Usually there's a problem with the rendering (eg maybe invalid xHTML?)
You'll also need to add the launchy gem to your project (eg gem 'launchy' in your Gemfile)
