View renders correctly in browser but tests fail on helper method?
I have a simple view and a helper that defines the title. Everything works fine if I pull up the view in the browser, but the rspec tests fail. Here's what I have:
Here are my tests:
describe PagesController do
render_views
before(:each) do
@base_title = "RoR Sample App"
end
describe "GET 'home'" do
it "should be successful" do
get 'home'
response.should be_success
end
it "should have the right title" do
get 'home'
response.should have_selector("title",
:content => @base_title + " | Home")
end
end
end
The Pages Controller:
class PagesController < ApplicationController
def home
@title = "Home"
end
def contact
@title = "Contact"
end
def about
@title = "About"
end
def help
@title = "Help"
end
end
The helper:
module ApplicationHelper
# Return a title on a per-page basis.
def title
base_title = "RoR22 Sample App"
if @title.nil?
base_title
else
"#{base_title} | #{@title}"
end
end
end
And the view:
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
</body>
</html>
It all renders properly in the browser, but the tests fail when it gets to <%= title %> line.
1) PagesController GET 'home' should be successful
Failure/Error: get 'home'
ActionView::Template::Error:
undefined local variable or method `title' for #<#<Class:0xabf0b1c>:0xabeec18>
# ./app/views/layouts/application.html.erb:4:in `_app_views_layouts_application_htm开发者_开发知识库l_erb___418990135_90147100_123793781'
# ./spec/controllers/pages_controller_spec.rb:12:in `block (3 levels) in <top (required)>'
Any idea what I'm doing wrong?
This is a known issue with spork. You can use this workaround in your prefork block:
Spork.trap_method(Rails::Application, :reload_routes!)
Spork.trap_method(Rails::Application::RoutesReloader, :reload!)
That's your application.html.erb. It can't see that method in the PagesHelper, you need to put that method in your ApplicationHelper. Only the views rendered by your PagesController can see PagesHelper. And it's a good idea to explicitly add return in your helpers.
It ends up the problem is that I was using the Spork gem to speed up my testing and for whatever reason spork wasn't registering that the ApplicationHelper had changed.
The solution was simply to reboot the spork gem and rerun the tests.
