I am using this to document my coding challenges in an diy and opensource manner.

Github CI will run the tests with rake.

Locally to play along ...

Install bundler if necessary

$ gem install bundler --no-ri --no-rdoc

Edit Gemfile to use the correct gems for your platform (optional).

Use bundler to install the gems.

$ bundle

Rename my_kata.rb and test_my_kata.rb and edit test_my_kata.rb to require the correct file for your kata, i.e. whatever you renamed my_kata.rb to.

Start guard to run your tests automatically.

$ guard

Do your kata! Guard will monitor your files and run your tests automatically whenever you make a change.
