Our CoreStory + Claude Test Generation playbook works perfectly with Claude Code! This supplement covers the setup and workflow differences. All prompting guidance, templates, and strategies from the main playbook apply identically.

Why Claude Code for Test Generation?

Claude Code offers several advantages for test generation:

• ✅ Direct filesystem writes - Tests written directly to your project, no downloads
• ✅ Immediate test execution - Run tests instantly after generation
• ✅ TDD workflow - Seamless cycle: generate tests → run → fix → iterate
• ✅ Already in your codebase - Full project context from the start
• ✅ CI/CD integration - Easy to script and automate
• ✅ Terminal integration - All your dev tools at hand

The Cross-Reference Advantage

Unlike Claude Desktop or Web, Claude Code can access both:

• CoreStory's architectural knowledge: Business rules, specs, design patterns
• Your actual source code: Implementation details, edge cases, real behavior

This enables Claude to cross-reference — comparing what code should do (from specs) with what it actually does (from source). The result:

• Richer test coverage: Test specified behavior AND actual implementation
• Catch spec drift: Identify when docs and code diverge
• Find hidden features: Discover undocumented functionality that needs tests
• Better alignment: Ensure tests match reality, not outdated specs
