oh-my-codex: Skill for Codex

UltraQA Skill

Comprehensive quality assurance with parallel testing.

When to Use

• Full test suite execution
• Quality gates before release
• Regression testing
• Test coverage improvement
• Bug hunting sessions

Test Categories

Unit Tests

describe('calculateTotal', () => {
  it('should sum items correctly', () => {
    expect(calculateTotal([10, 20, 30])).toBe(60);
  });

  it('should handle empty array', () => {
    expect(calculateTotal([])).toBe(0);
  });

  it('should handle negative numbers', () => {
    expect(calculateTotal([10, -5])).toBe(5);
  });
});

Integration Tests

describe('User API', () => {
  it('should create and retrieve user', async () => {
    const created = await api.createUser({ name: 'Test' });
    const retrieved = await api.getUser(created.id);
    expect(retrieved.name).toBe('Test');
  });
});

E2E Tests

test('user can complete checkout', async ({ page }) => {
  await page.goto('/products');
  await page.click('[data-testid="add-to-cart"]');
  await page.click('[data-testid="checkout"]');
  await page.fill('#email', '[email protected]');
  await page.click('[data-testid="place-order"]');
  await expect(page.locator('.success')).toBeVisible();
});
