Load phases as needed:

Core Principles

1. ONE test file per response - Never generate all at once
2. Map to ACs - Every test traces to acceptance criteria
3. Coverage targets - 80%+ for critical paths

Quick Reference

Test Coverage Matrix

Test Types

• Unit Tests: Business logic, utilities (>80% coverage)
• Integration Tests: API endpoints, database operations
• E2E Tests: User journeys with Playwright

E2E Test Example (Playwright)

import { test, expect } from '@playwright/test';

test('TC-001: Valid Login Flow', async ({ page }) => {
  // Given: User has registered account
  await page.goto('/login');

  // When: User enters valid credentials
  await page.fill('[name="email"]', 'test@example.com');
  await page.fill('[name="password"]', 'SecurePass123');
  await page.click('button[type="submit"]');

  // Then: Redirect to dashboard
  await expect(page).toHaveURL('/dashboard');
});

Workflow

1. Analysis (< 500 tokens): List test files needed, ask which first
2. Generate ONE test file (< 800 tokens): Write to file
3. Report progress: "X/Y files complete. Ready for next?"
4. Repeat: One file at a time until done

Token Budget

• Analysis: 300-500 tokens
• Each test file: 600-800 tokens

NEVER exceed 2000 tokens per response!
