Refactoring Workshop

Requirements: Ruby >1.9.3, git, minitest gem.

Each folder is named after the refactoring pattern they tackle, and contains:

• app.rb code we'll refactor.
• setup.rb necessary code for app.rb to run (mimicks a SUPER BASIC Rails) We don't need to see/edit it unless just curious. :-)
• tests.rb self explanatory. Necessary for daily life, specially for refactoring.

You may run tests by running tests.rb or app.rb files, like:

$ ruby app.rb
Run options: --seed 53634

# Running:
..

Refactoring Patterns

1. Intention Revealing Method

2. Special Case Object

3. Replace Method with Method Object

Implementation note: folder contains two fixture files needed for tests, fixtures/input.csv and fixtures/output.csv, and doesn't include setup.rb.

4. Service Object
