TypeScript Testing Rules (Frontend)

Test Framework

• Vitest: This project uses Vitest
• React Testing Library: For component testing
• MSW (Mock Service Worker): For API mocking
• Test imports: import { describe, it, expect, beforeEach, vi } from 'vitest'
• Component test imports: import { render, screen, fireEvent } from '@testing-library/react'
• Mock creation: Use vi.mock()

Basic Testing Policy

Quality Requirements

• Coverage: Unit test coverage must be 60% or higher (Frontend standard 2025)
• Independence: Each test can run independently without depending on other tests
• Reproducibility: Tests are environment-independent and always return the same results
• Readability: Test code maintains the same quality as production code
