Review: SOLID Principles and Clean Code

When to Use

• Pull request review when code smells are present
• After detecting Bloater or Change Preventer smells (see detect-code-smells)
• A class or module is hard to test in isolation
• A change in one place forces changes in many others

SOLID Principles

SRP -- Single Responsibility Principle

One class = one reason to change.

Red Flags: Class name contains "Manager"/"Utils", 10+ public methods spanning unrelated domains, unrelated imports.
