Module 6: OO Architecture & Automated Testing

  • SOLID Principles in Drupal: Writing testable, modular code.
  • Services & Factories: Creating custom services to encapsulate business logic (keeping .module files empty).
  • Automated Testing: Writing Kernel Tests and Unit Tests (PHPUnit) to verify your logic.
  • Static Analysis: Implementing PHPCS and PHPStan to catch errors before you even run the code.
