How do you tell rails to generate integration tests using rspec and webrat?

I'm working through the Ruby on Rails Tutorial and I'm getting stuck on the integration tests.开发者_StackOverflow When I try to generate the integration tests for layout_links, I get the following comments in the generated test:

# Run the generator again with the --webrat flag if you want to use webrat methods/matchers

And I don't see the "response.should be_success" syntax that I expect. I think I've managed to hose my installation somehow but I don't know how to see which gems I have on the system and how to uninstall/reinstall them.

[edit]I do have webrat configured in the "test" section of my Gemfile:

source 'http://rubygems.org'

gem 'rails', '3.0.5'
gem 'sqlite3-ruby', '1.3.2', :require => 'sqlite3'

group :development do
      gem 'rspec-rails', '2.5.0'
end

group :test do
      gem 'rspec', '2.5.0'
      gem 'webrat', '0.7.1'
end

Any help would be greatly appreciated.

I believe that message means that webrat was not detected when the scaffold was generated. Look in your projects Gemfile for:

gem 'webrat'

Add it if it's missing, then run bundle install, then run the generator again.

I've gotten this to work and the problem seems to be my ruby/rails installation. I'm running Ubuntu and I think I've mixed a few packages installed via apt with those installed via bundle and gotten my system confused. I've followed this tutorial on installing Ruby on Rails in Ubuntu using rvm and now I can generate and run my tests again. I'm still having a few issues with autotest which I believe are related to conflicting packages. rvm looks like it's a much better way to set up a rails environment than apt and it allows you to only install your rails environment for one user. This way, you can set up a test user to make sure you get everything configured correctly without changing your entire system.

Thanks for all of the help.
