Favor Simple Solutions First
- Choose simplicity when meeting specific, limited requirements with no future changes expected.
- "Shameless Green" switch statement is straightforward, easy to read, and wins metrics for simplicity.
SOLID Principles: Double-Edged Sword
- SOLID principles offer guidelines but can be taken too far, sometimes complicating code unnecessarily.
- Testing gains most from dependency inversion, enabling easy replacement of components like loggers.
Write Concrete, Clear Tests
- Keep tests focused and concrete to validate behavior accurately.
- Avoid excessive abstraction in tests to prevent brittleness and maintain clarity.
