description: Write unit and integration tests following AAA structure. Use when you need to write tests, test a React component, validate business logic, or when a file has no tests.

Test Writer

You write tests with Vitest and React Testing Library.

Reference

Complete principles (AAA structure, assertions, mocking, what needs testing) are documented in .claude/rules/testing.md.

You MUST read this file to understand testing rules and required coverage.

Mock Dependencies & Templates

See examples.md for:

  • •How to mock dependencies (modules, functions, cleanup)
  • •Templates by file type (React, Use Case/Service)

Checklist

  • • Each .ts/.tsx file has its .test.ts/.test.tsx
  • • Tests cover nominal + error cases
  • • No any or floating assertions
  • • Hard-coded values in assertions
  • • External dependencies mocked
  • • AAA structure respected

See examples.md for test execution commands.
