im working on ruby.railstutorial.org/ruby-on-rails-tutorial-book. Im using rails 3.2.7, spork, rspec, capybara, launchy and some guards :)
i have a really weird problem in Chapter 3 with testing:
It seems like the tests arent working for what is inside the <head>-Tag. If i put the <title>-tag inside the <body>-tag instead of the head-tag it works fine.
Also it works when i put <h1>-tags above the <title> inside <head>-Tags. It is weird, isnt it?
Please help me figur out.
The example is from : 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
The Error-Message is:
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 '
That one is working:
it "should have the h1 'Sample App'" do
visit '/static_pages/home'
page.should have_selector('h1', :text => 'Sample App')
end
the rendered HTML-file:
<!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>
Thanks
Edit: you can find the files im working with on github: https://github.com/farukg/sample_app/
the link to the spec file: https://github.com/farukg/sample_app/blob/master/spec/requests/static_pages_spec.rb
Explanation of what i did: The code for Home page is like it should be. The code for about page has its own layout with a h1-tag above title-tag inside to show that it works for some kind of reason. And finally the help page has its title tag inside the body tags which works too.
Im am absolutly confused, why do i have such a strange behaviour?

It's just because <title> is in the <head> so it doesn't appear.
Using this, solved my problem:
page.should have_selector 'title', :visible => false
Tip: You can apply the same to check other <head> elements, like <meta>, for example, to be sure you're (and you'll stay) Google-friendly.

I just checked your project on Github, and it seems that you are using the edge version of capybara:
Gemfile
gem 'capybara', :git => 'git://github.com/jnicklas/capybara.git'
Gemfile.lock
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)
If nothing else, I would dare say this is the cause of your problem. (And sure enough, my reference project is broken all over after updating capybara to use the edge version)
So, unless you are keen to help with the beta testing of Capybara 2, you would do well to stick to the 1.1.2 version as listed here.

If you're using Capybara 2, you can use the have_title method like this:
page.should have_title("Ruby on Rails Tutorial Sample App | Home")
