Slanger for Pusher testing?

• Nobody has used Slanger.

Rspec and_call_original

New with Rspec 2.12, rspec mocks now have the ability to call through to the original implementation.

banana.should_receive(:split).and_call_original

asserts that banana.split was called, and also executes banana.split

Don’t commit Gemfile.lock in your gems

See http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/

tl;dr

ACCORDING TO YEHUDA … if you are maintaining a GEM

git rm –cached Gemfile.lock
echo “Gemfile.lock” >> .gitignore
git add .gitignore
git ci -m “Remove Gemfile.lock — cf. http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gem”
