Refactor with Factory Design Pattern

on YouTube ↗23m

" summary

Refactors a sprawling switch-based CSV importer into a class-per-format solution using a Factory pattern that returns objects implementing a schedule type interface with methods to detect type, format dates, extract lines, check duplicates and yield time slots. Built as CakePHP classes (inheritance, traits, collections) and a thin controller/behavior, it produces a CakePHP ORM entity that parses three real formats. Unit tests run the same data provider against legacy and refactored code and show matching 20, 9, 8 results, proving the refactor works.
