Quality Assurance

Quality assurance is a delivery system, not a phase. Reconstruct intended behavior, choose the cheapest evidence that can prove or falsify it, then wire the same verification into repeatable local and CI workflows.

In command examples below, <skill-dir> means the installed quality-assurance skill directory and <repo-root> means the target repository root.

Quick-Start Example

A minimal Jest unit test illustrating the key patterns this skill enforces:

// ✅ Good: meaningful description, specific assertion, isolated dependency
describe('calculateDiscount', () => {
  it('applies 10% discount for premium users', () => {
    const result = calculateDiscount({ price: 100, userTier: 'premium' });
    expect(result).toBe(90); // specific outcome, not just truthy
  });
