I am on Chapter 4 of Michael Hartl’s RoR tutorial, and having some troubles with rspec and using the full_title helper function. In part 4.1 of the tutorial, I have the helper code as follows. It’s purpose is to make it so my help, contact, home, and about pages don’t need to be supplied a title on each view.
module ApplicationHelper
# Returns the full title on a per-page basis.
def full_title(page_title)
base_title = "Ruby on Rails Tutorial Sample App"
if page_title.empty?
base_title
else
"#{base_title} | #{page_title}"
end
end
end
My layout page looks like
<!DOCTYPE html>
<html>
<head>
<title><title><%= full_title(yield(:title)) %></title></title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
and my static_pages_spec.rb file looks like:
require 'spec_helper'
describe "Static Pages" do
include ApplicationHelper
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 base title 'Home'" do
visit '/static_pages/home'
page.should have_selector('title',
:text => "Ruby on Rails Tutorial App")
end
it "should not have a custom page title" do
visit '/static_pages/home'
page.should_not have_selector('title', :text => '| Home')
end
end
describe "Help page" do
it "should have the h1 'Help'" do
visit '/static_pages/help'
page.should have_selector('h1', :text => 'Help')
end
it "should have the right title 'Help'" do
visit '/static_pages/help'
page.should have_selector('title',
:text => "#{base_title} | Help")
end
end
describe "About us" do
it "should have the h1 'About Us'" do
visit '/static_pages/about'
page.should have_selector("h1", :text => "About Us")
end
it "should have the right title 'About Us'" do
visit '/static_pages/about'
page.should have_selector('title',
:text => "#{base_title} | About Us")
end
end
describe "Contact" do
it "should have the h1 'Contact'" do
visit '/static_pages/contact'
page.should have_selector('h1', :text => "Contact")
end
it "should have the right title 'Contact'" do
visit '/static_pages/contact'
page.should have_selector('title',
:text => "#{base_title} | Contact")
end
end
end
Yet when I run rspec, I get 4 test failures. 3 of them refer to the contact, about us, and help pages and say something along the lines of
Failure/Error: :text => “#base_title} | Contact”)
NameError:
undefined local variable or method “base_title” for #
Can anyone tell me what’s going wrong here? I suspect it has something to do with the helper function ans the base_title variable not being recognized by Rspec, but according to the tutorial the test suite should be passing all green.
Update: I figured out why one of the tests was failing. But I still have a problem with those 3 views saying base_title is an undefined method.
In the following test, how rspect knows what is
base_title(2nd last line).You have not defined it. I guess that’s why your tests are failing.
