# 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 across functional, performance, and security perspectives 3. **Write tests** — Implement tests with proper assertions (see example below) 4. **Execute** — Run tests and collect results - If tests fail: classify the failure (assertion error vs. environment/flakiness), fix root cause, re-run - If tests are flaky: isolate ordering dependencies, check async handling, add retry or stabilization logic 5. **Report** — Document findings with severity ratings and actionable fix recommendations - Verify coverage targets are met before closing; flag gaps explicitly ## Quick-Start Example A minimal Jest unit test illustrating the key patterns this skill enforces: ```js // ✅ 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 }); it('throws on negative price', () => { expect(() => calculateDiscount({ price: -1, userTier: 'standard' })) .toThrow('Price must be non-negative'); }); }); ``` Apply the same structure for pytest (`def test_…`, `assert re...
