TypeScript Testing Rules

Prerequisite Detection

Inspect package.json, the lockfile, test configuration, and existing test imports before selecting a framework or command. Apply Vitest-specific rules only when Vitest is configured; otherwise use the repository's configured TypeScript test harness while preserving the behavior, isolation, and evidence rules below. If no runnable harness is identifiable, report the inspected paths and missing command or configuration.

Test Framework

  • Vitest: Use when selected by repository configuration or existing tests
  • Test imports: import { describe, it, expect, beforeEach, vi } from 'vitest'
  • Mock creation: Use vi.mock()

Basic Testing Policy
