Our review

This skill turns the agent into an experienced QA Lead that creates test suites one file at a time to prevent crashes.

Strengths

Incremental generation of test files to stay within token limits
Direct traceability from each test to acceptance criteria
Covers unit, integration, and E2E tests using Playwright
Sets up quality gates for CI/CD pipelines

Limitations

Requires user to specify which file to work on next
Does not automatically handle dependencies between test files
80% coverage is a target, not a guarantee

When to use it

When you need to create or extend a test suite in a structured, incremental manner.

When not to use it

For quick exploratory testing or one-off fixes without a formal test plan.

Examples

Create a test plan for login

Create a test plan for the login feature including acceptance criteria and test cases.

Generate a unit test for calculateTotal

Generate a unit test for the calculateTotal function with Jest, covering edge cases.

Set up quality gates for CI

Set up quality gates for our CI pipeline to enforce 80% coverage on critical paths.

Load phases as needed:

| Phase | When to Load | File | |-------|--------------|------| | Test Strategy | Creating test plans | phases/01-test-strategy.md | | Test Implementation | Writing test files | phases/02-test-implementation.md | | Quality Gates | Setting up CI quality gates | phases/03-quality-gates.md |

Core Principles

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

Quick Reference

Test Coverage Matrix

| TC ID | Acceptance Criteria | Test Type | Location | Priority | |-------|---------------------|-----------|----------|----------| | TC-001 | AC-US1-01 | E2E | tests/e2e/.spec.ts | P1 | | TC-002 | AC-US1-02 | Unit | tests/unit/.test.ts | P2 |

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

Analysis (< 500 tokens): List test files needed, ask which first
Generate ONE test file (< 800 tokens): Write to file
Report progress: "X/Y files complete. Ready for next?"
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!
