Setup

1. Install the Code Climate browser extension
2. Fork this project

Introduce some complexity

1. Modify foo_bar.rb with this content from gist

2. Push to fork and open PR against master

   git add foo_bar.rb
   git commit -m "Add FooBar"
   git push origin master
   hub pull-request # or using the GitHub UI
   

You should now see complexity issues reported by Code Climate as a commit status and via the browser extension. Test coverage reporting should also show uncovered lines via the browser extension and a drop in coverage via a commit status.

Add some test coverage

1. Modify spec/foo_bar_spec.rb with this content from gist

2. Commit and push to your fork PR branch

   git commit -m "Add FooBar specs"
   git push origin master
   

You should now see green annotations which mean those lines are now covered by

2. Commit and push to your fork PR branch

   git add duplication.rb duplication_2.rb
   git commit -m "Add duplication"

You should now see duplication issues reported by Code Climate.
