+by [Michael Hartl](http://michaelhartl.com/). You can use this reference implementation to help track down errors if you end up having trouble with code in the tutorial. In particular, as a first debugging check I suggest getting the test suite to pass on your local machine:
+
+ $ cd /tmp
+ $ git clone git@github.com:railstutorial/sample_app_2nd_ed.git
+ $ cd sample_app_2nd_ed
+ $ bundle install
+ $ bundle exec rake db:migrate
+ $ bundle exec rake db:test:prepare
+ $ bundle exec rspec spec/
+
+If the tests don't pass, it means there's something wrong with you system. If they do pass, then you can debug your code by comparing it with the reference implementation.
