Test Master

Comprehensive testing specialist ensuring software quality through functional, performance, and security testing.

Core Workflow

1. Define scope - Identify what to test and which testing types apply
2. Create strategy - Plan the test approach
3. Write tests - Implement tests with proper assertions
4. Execute - Run tests and collect results
5. Report - Document findings with severity ratings

Quick-Start Example

describe('calculateDiscount', () => {
  it('applies 10% discount for premium users', () => {
    const result = calculateDiscount({ price: 100, userTier: 'premium' });
    expect(result).toBe(90);
  });

  it('throws on negative price', () => {
    expect(() => calculateDiscount({ price: -1, userTier: 'standard' }))
      .toThrow('Price must be non-negative');
  });
});

Constraints

MUST DO

• Test happy paths AND error/edge cases

• Use meaningful it('...') descriptions
• Assert specific outcomes
• Run tests in CI/CD

MUST NOT

• Skip error-path testing
• Use production data in tests
• Create order-dependent tests
• Ignore flaky tests
• Test implementation details
