martinholovskySkill

sota-testing

martinholovsky/SOTA-skills/skills/sota-testing/SKILL.md

State-of-the-art software testing strategy and practice (2026) for designing test strategy, writing unit/integration/e2e tests, or auditing test suites. Covers suite shape (pyramid/trophy/honeycomb), test design quality (behavior-first, AAA, determinism, smells), test doubles (mocks/fakes/stubs), test data (builders over fixtures), real-dependency integration (Testcontainers-style), contract testing (Pact/consumer-driven), e2e/UI strategy (selectors, auto-waiting, flake economics), property-based testing, fuzzing, mutation testing, approval testing, and suite health/CI (flaky-test policy, coverage philosophy, sharding). Trigger keywords - testing, test strategy, unit test, integration test, e2e, end-to-end, coverage, flaky tests, TDD, contract testing, property-based, mocking, fixtures, snapshot test, mutation testing, fuzzing, BDD, Gherkin, given-when-then, acceptance criteria, security testing, WSTG, IDOR test, authz test, abuse case, DAST. Use for BOTH building and auditing test suites.

nunitSkill

nunit-testing

nunit/nunit/.claude/skills/nunit-testing/SKILL.md

Use when writing or modifying tests in NUnit's own test projects, or when making a behavioral change to production code that needs test coverage. Covers test structure, attribute choice, helper visibility, platform guards, and which test projects are real.

filipstrandSkill

mflux-testing

filipstrand/mflux/.cursor/skills/mflux-testing/SKILL.md

Run tests in mflux (fast/slow/full), preserve image outputs, and handle golden image diffs safely.

techygargSkill

test-quality

techygarg/lattice/skills/test-quality/SKILL.md

Apply test quality principles when generating or reviewing test code. Enforces Arrange-Act-Assert structure, one behavior per test, assertion quality, test isolation, meaningful naming, and test data management. Use when writing tests, reviewing test code, or when the user mentions 'write tests', 'test this', 'test quality', 'test review', 'improve tests', or 'test structure'. Loaded automatically by the code-generating molecules (code-forge, refactor-safely, bug-fix). This skill governs the craft of writing individual test cases -- not what to test (that is driven by the code being implemented) but how to write tests that are reliable, readable, and maintainable.

Feel-ix-343Skill

testing-helix

Feel-ix-343/markdown-oxide/.agents/skills/testing-helix/SKILL.md

s3s-projectSkill

fuzz-testing

s3s-project/s3s/.agents/skills/fuzz-testing/SKILL.md

Add, run or schedule a fuzz target in this repository. Use when a target is added or renamed, when a scheduled run fails, when a crash has to be reproduced from an artifact, or when the fuzz budget and rotation are discussed.

chunkydotdevSkill

ab-testing

chunkydotdev/email-skills/skills/content/ab-testing/SKILL.md

Run email A/B tests with statistical rigor. Use when testing subject lines, content variants, send times, CTAs, or measuring experiment significance.

lobehubSkill

local-testing

lobehub/lobe-ui/.agents/skills/local-testing/SKILL.md

Local browser verification for the lobe-ui component library and documentation site. Uses agent-browser against the React Router and Vite development server, including component pages, manifest-backed standalone demos, theme states, and responsive layouts. Trigger on local test, UI test, verify component, test in browser, visual check, or screenshot demo.

grafanaSkill

k6-perf-test-website

grafana/skills/skills/grafana-k6/k6-perf-test-website/SKILL.md

Use when the user wants to performance-test, load-test, or stress-test a public website end-to-end with k6. Produces a hybrid (protocol + browser) test suite, SLO-backed thresholds, a load-generator monitor sidecar, and a Grafana-side investigation playbook for backends the user owns. Triggers on "perf test my site", "performance test my site", "load test this URL", "stress test my web app", "I want to load test [URL]", "set up k6 against my website", "write a k6 suite for [site]", "see if my site handles N concurrent users", or "how does my site perform under traffic". Use this skill whenever the user mentions k6, load testing, stress testing, performance testing, or wants to validate a website under traffic — even if they don't explicitly use the word "test" or ask for the specific outputs this skill produces. This skill is for a full multi-test suite across several workflows; for a single browser test — functional OR a browser load test measuring Web Vitals for one journey — use k6-browser-test.

eduardo-slSkill

go-test-quality

eduardo-sl/go-agent-skills/skills/(testing)/go-test-quality/SKILL.md

Go testing patterns for production-grade code: subtests, test helpers, fixtures, golden files, httptest, testcontainers, fuzz testing, and testing/synctest. Covers mocking strategies, test isolation, coverage analysis, and test design philosophy. Use when writing tests, improving coverage, reviewing test quality, setting up test infrastructure, or choosing a testing approach. Trigger examples: "add tests", "improve coverage", "write tests for this", "test helpers", "mock this dependency", "integration test", "fuzz test", "flaky test", "synctest", "goroutine leak in tests". Not for: benchmarking methodology (go-performance-review), security testing (go-security-audit), table-driven patterns (go-test-table-driven).

e2e-testing

CrowdStrike/foundry-skills/skills/e2e-testing/SKILL.md

End-to-end testing for Falcon Foundry apps using Playwright and @crowdstrike/foundry-playwright. TRIGGER when user asks to "add e2e tests", "add playwright tests", "write end-to-end tests", "test my app", or mentions "e2e", "playwright", or "end-to-end" in the context of testing a Foundry app. DO NOT TRIGGER during normal app creation, UI development, or function development. This skill is opt-in; not all apps need e2e tests.
