tdd - Want to add rspec to my rails 3 app, what do I need to do? -

i updated gemfile with:

 group :development, :test      gem 'rspec'     gem 'webrat'     gem 'rspec-rails'  end 

and ran bundle install.

now have homecontroller, manually created this:

/spec/controllers/home_controller_spec.rb 

i don't have page started test off with:

require 'spec_helper'  describe homecontroller    describe "get 'about'"     "should successful"       'about'       response.should be_success     end   end   end 

now did:

rspec spec/ 

do need update other files rspec work, don't understand error message.

update

i changed if it, i'm getting:

file load -- spec_helper (loaderror)     /users/someuser/.rvm/rubies/ruby-1.8.7-p302/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'     /users/someuser/dev/rscs/example.com/spec/controllers/home_controller_spec.rb:1     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/configuration.rb:327:in `load'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/configuration.rb:327:in `load_spec_files'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/configuration.rb:327:in `map'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/configuration.rb:327:in `load_spec_files'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/command_line.rb:18:in `run'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/runner.rb:55:in `run_in_process'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/runner.rb:46:in `run'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/gems/rspec-core-2.2.1/lib/rspec/core/runner.rb:10:in `autorun'     /users/someuser/.rvm/gems/ruby-1.8.7-p302@rails3/bin/rspec:19 

see top line of backtrace.

/users/someuser/dev/rscs/example.com/spec/controllers/home_controller_spec.rb:6: syntax error, unexpected kdo, expecting kthen or ':' or '\n' or ';' (syntaxerror) 

that error message points syntax error in spec file—namely, on line 6, there do not expected. that's should check first.

if "should successful" 

i'm betting meant if it ;) it rspec method defining particular aspect of class test, , it, unlike if operator, can take block.
