tdd

v0.4.9

A TDD knowledge base distilled from cover-to-cover readings of Kent Beck's Test-Driven Development: By Example and Vladimir Khorikov's Unit Testing: Principles, Practices, and Patterns. Fourteen author-attributed reference files behind a routing table, plus a no-load quick decision guide, answer the WHY behind test design decisions.

Included Skills1

principlesskills/principles/SKILL.md

Answers test design questions from authoritative TDD sources (Beck, Khorikov), producing WHY reasoning to improve test design decisions. Use when: 'should I mock this', 'four pillars of a good test', 'red green refactor', 'classical vs london school', 'test doubles', 'testing anti-patterns', 'resistance to refactoring', 'code coverage', 'observable behavior', 'humble object', 'integration test', 'test pyramid', 'output vs state vs communication test'. Not for HOW to run tests in the project (use the project's own test tooling and workflow for that).
