Refactoring Workshop

Requirements: Ruby >= 2.7, 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. :-)
test_app.rb self explanatory. Necessary for daily life, specially for refactoring.

Run bundle to make sure you have the gems needed for running tests (rake and minitest).

Run tests running rake:

$ rake
Run options: --seed 61694

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
