FAQPage Schema
What is a deep module in software architecture?

A deep module in software architecture features a small interface hiding a large implementation, maximizing leverage and testability while reducing system complexity for callers.

How do I design better module interfaces for maintainability?

To design better module interfaces for maintainability, focus on creating deep modules with small interfaces, classify dependencies, and replace old unit tests with interface-level tests.

What is the Design It Twice pattern for code design?

The Design It Twice pattern is a parallel sub-agent approach for exploring and comparing different interface designs for a module deepening candidate before final implementation.

How do I classify module dependencies for testing strategies?

Classify module dependencies by analyzing their integration points to determine appropriate testing strategies, ensuring seams are correctly located for better interface-level test coverage.

When do I need to analyze seam management in module architecture?

Analyze seam management in module architecture when refactoring for testability, ensuring the right location for seams is chosen to separate dependencies and simplify interface testing.

Does this approach work without specific framework dependencies?

Yes, this codebase design approach works without specific framework dependencies, providing shared vocabulary and strategies applicable to any module architecture independent of platform.
