Views are normally (for good reason) not rendered in controller specs. If you need it to happen, use:

RSpec 1 (Rails 2):

Rails Long Term Support

Rails LTS provides security patches for old versions of Ruby on Rails (2.3, 3.2, 4.2 and 5.2)

• Prevents you from data breaches and liability risks
• Upgrade at your own pace

RSpec 2 (Rails 3):

render_views Show archive.org snapshot

Note that you can't use that inside it blocks but need to put it in the nesting example group, like this:

    describe '#update' do
      context 'when rendering views' do
        
        integrate_views
        
        it 'should not fail' do
          # This will detect errors that happen during view rendering as well:
          expect { put :update, :id => 23 }.to_not raise_error
        end

      end
    end

Wrap spec examples into their own "rendering" context so you don't render views for other specs that don't need it to happen.
