About

What it does

cashwu-claude-code-tdd-marketplace packages two Test-Driven Development approaches for Claude Code: Kent Beck’s organic style, where design emerges naturally through small cycles, and a structured Test-First path that is more plan-driven and documentation-friendly. Solo builders shipping APIs, CLIs, or SaaS backends can install one or both plugins to keep the agent honest about writing failing tests first, implementing the minimum code to pass, and refactoring without skipping verification. The marketplace is narrow by design—two focused plugins rather than a full delivery suite—so it pairs well with your existing editor and CI setup rather than replacing it. Use organic TDD when exploring behavior and letting interfaces evolve; use structured Test-First when you already know acceptance criteria and want explicit test specs up front. Intermediate comfort with unit tests and your project’s test runner is assumed. After registration, invoke the plugin that matches your sprint ritual and let Claude maintain the red-green-refactor loop while you review diffs and keep commits small.

Highlights

  • Two complementary TDD plugins: Kent Beck organic TDD and structured Test-First TDD
  • Small iterative cycles with design emerging from tests
  • Plan-driven and documentation-oriented structured test-first flow
  • Suited to backend and API logic where automated verification pays off quickly

Why builders use it

Builders who want TDD with AI assistants often get implementation-first code that skips failing tests and leaves design undocumented.

Installing the marketplace lets you run consistent organic or structured test-first cycles so features grow through verified, iterative red-green-refactor work.
