test-master
Generates test files, creates mocking strategies, analyzes code coverage, designs test architectures, and produces test plans and defect reports across functional, performance, and security testing disciplines. Use when writing unit tests, integration tests, or E2E tests; creating test strategies or automation frameworks; analyzing coverage gaps; performance testing with k6 or Artillery; security testing with OWASP methods; debugging flaky tests; or working on QA, regression, test automation, quality gates, shift-left testing, or test maintenance.

git clone https://github.com/Jeffallan/claude-skills /tmp/claude-skills && ln -s /tmp/claude-skills/skills/test-master ~/.claude/skills/test-master
From README
Test Master Comprehensive testing specialist ensuring software quality through functional, performance, and security testing. Core Workflow 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 Quick-Start Example 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.
