Testing & Software Practices Skill

Overview

Standard software engineering and testing practices for library development.

Test-Driven Development (TDD)

• Write tests before the implementation.
• Focus on the interface and expected behavior first.
• Use pytest for Python and bun test for TypeScript.

Property-Based Testing

• Use Hypothesis in Python to generate edge cases and verify invariants.
• Focus on "state-based" testing for core domain logic.

Single Responsibility Principle (SRP)

• Each class or function should have one reason to change.
• Keep components focused and modular.

KISS (Keep It Simple, Stupid)

• Favor readability over cleverness.
• Maintain a clear and simple domain model.

Dependency Injection (DI)

• Inject dependencies (telemetry, storage, etc.) rather than hard-coding.
• This allows for easier testing and mocking.

Extended Knowledge (Deep Context)
