Rails-Controller-testing breaks View specs.

[b-sridhar]

After adding the rails-controller-testing gem, the View specs fail as the "render" method is no longer recognized.

Environment: Rails: Rails 5.0.0.beta1.1, Ruby: ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
Steps to reproduce:

1. rails new example
2. cd example
3. echo 'gem "rspec-rails", :group => [:development, :test]' >> Gemfile
4. Uncomment "gem 'therubyracer', platforms: :ruby" in the Gemfile.
5. Bundle update.
6. rails generate rspec:install
7. rails generate scaffold Widget name:string
8. rake db:migrate && rake db:test:prepare
9. bundle exec rspec spec [Only the controller test fails.]
10. Add "gem 'rails-controller-testing'" to the Gemfile.
11. Add the following to rails_helper.rb:
    config.include Rails::Controller::Testing::TestProcess
    config.include Rails::Controller::Testing::TemplateAssertions
    config.include Rails::Controller::Testing::Integration
12. bundle update.
13. bundle exec rspec spec/views
14. View specs fails for named paths while invoking render with the following error:

widgets/show renders attributes in <p>
     Failure/Error: render
     ActionView::Template::Error:
