test-master

Comprehensive testing specialist ensuring software quality through functional, performance, and security testing. A minimal Jest unit test illustrating the key patterns this skill enforces: Apply the same structure for pytest ( def test_… , assert result == expected ) and other frameworks. Load detailed guidance based on context: MUST DO MUST NOT When creating test plans, provide: - Define scope — Identify what to test and which testing types apply - Create strategy — Plan the test approach across functional, performance, and security perspectives - Write tests — Implement tests with proper assertions (see example below) - 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 - Report — Document findings with severity ratings and actionable fix recommendations - Verify coverage targets are met before closing; flag gaps explicitly - Test happy paths AND error/edge cases (e.g., empty input, null, boundary values) - Mock external dependencies — never call real APIs or databases in unit tests - Use meaningful it('…') descriptions that read as plain-English specifications - Assert specific outcomes ( expect(result).toBe(90) ), not just truthiness - Run tests in CI/CD; document and...
