Question

I am trying to get my test suite working and am having some issues.

#home_controller_spec.rb
require 'spec_helper'

describe HomeController do
  describe "GET 'index'" do
    it "should be successful" do
      get 'index'
      response.should be_success
    end
    it "should have the right h2" do
      get 'index'
      response.should have_selector('h2', :content => 'Home')
    end
  end
end

The first test works and passes just fine. Any time I try to run

response.should have_selector('[anything]')

it gives this error:

2) HomeController GET 'index' should have the right h2
   Failure/Error: response.should have_selector('h2','Home')
   expected css "Home" to return something
 # ./spec/controllers/home_controller_spec.rb:12:in `block (3 levels) in <top (required)>'

I’m using Rails 3.1 and RSpec 2.6 and have already uninstalled and reinstalled Rspec. The same result happens in all of my controller tests.

Any ideas how to fix this error?

Thanks in advance!

Edit:
Uninstalled all gems. Reinstalled all gems. Re-setup RSpec, Capybara and Guard. Seems to be working now. Thanks for the help. Not sure what was wrong.

Answer 1

By default RSpec doesn’t render templates in controller specs. You can either:

1) Move the test into a view spec

2) Add render_views to the describe block in the controller spec, which will then render the template.

Option 1 is preferred IMO. You could also use a request spec to test for content. If you are writing request specs, view specs are usually superfluous.
