Before refactoring/changing code, you need to locate the tests that will use this code. who_called_me helps you track those usages.

How to install :

gem install who_called_me

How to use :

1° call 'who_called_me' in the method you want to track.

..
def foo
  who_called_me         # <-- just insert this 
  ...
end
..

2° run the tests / the application

When the tests/application exits, a report is printed in the console that looks like :

---------------------------------------------------------------------------------------------------
who_called_me report :
======================

== Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
