typescript-eslintSkill

tests

typescript-eslint/typescript-eslint/.agents/skills/tests/SKILL.md

Write rule test cases the way this repo expects — one logical unit per test case, static self-contained snippets, comments only when they add meaning, and precise error assertions. Use when adding or changing tests in packages/eslint-plugin/tests/rules or reviewing a PR that touches rule tests.

MicrosoftReads credentialsSkill

testing-course-samples

microsoft/ai-agents-for-beginners/translations/en/.agents/skills/testing-course-samples/SKILL.md

Use when asked to validate, test, smoke-test, or run the course's notebook

usestrixSkill

owasp-top-10-testing

usestrix/strix/skills/owasp-top-10-testing/SKILL.md

Test an application against the OWASP Top 10 with Strix — autonomous AI agents that attempt real exploits for each category of the current OWASP Top 10:2025 (broken access control including SSRF, security misconfiguration, software supply chain failures, cryptographic failures, injection, insecure design, authentication failures, integrity failures, logging and alerting failures, mishandling of exceptional conditions) and report only what they could actually prove, mapped back to the category with a proof-of-concept. Also covers the OWASP API Security Top 10 (2023). Use when the user asks for an OWASP Top 10 assessment, OWASP compliance testing, or a security review mapped to OWASP categories.

open-metadataSkill

java-affected-tests

open-metadata/OpenMetadata/skills/java-affected-tests/SKILL.md

Use before opening or updating an OpenMetadata PR that changes Java, a JSON schema, an index mapping, a SQL migration, seed data or a pom — PR CI no longer runs the Java integration tests (they run only in the merge queue) and the JavaUIIT/search-it suites run only nightly, so this selects the unit tests and integration tests the diff can break, runs them in the lane and engine CI uses, and records the results in the PR body. Also use when asked which Java tests to run for a change, or how to run one integration test.

tldrawSkill

spec-driven-tests

tldraw/tldraw/skills/spec-driven-tests/SKILL.md

Rebuild a package's unit test suite around a behavior specification (SPEC.md) derived from the implementation, with every test citing a numbered rule ID. Use when asked to do a spec-driven test rebuild, write a SPEC.md for a package, repeat the state or store spec process (PRs #9158, #9172) for another package, or rebuild tests around a spec.

MaterializeIncSkill

mz-limits-test

MaterializeInc/materialize/.agents/skills/mz-limits-test/SKILL.md

Add/modify/debug limits test. Trigger: "limits test", "Generator subclass", "many objects", "scaling test", or stress-test Materialize with many objects (tables, views, sources, indexes). Also edits in test/limits/mzcompose.py.

entireioSkill

test-repo

entireio/cli/.claude/skills/test-repo/SKILL.md

Use this skill to test strategy changes against a fresh test repository. Invoke when the user asks to "test against a test repo", "validate the changes", or wants to verify session hooks, commits, and checkpoint creation work correctly.

documensoSkill

envelope-editor-v2-e2e

documenso/documenso/.agents/skills/envelope-editor-v2-e2e/SKILL.md

Writing and maintaining Playwright E2E tests for the Envelope Editor V2. Use when the user needs to create, modify, debug, or extend E2E tests in packages/app-tests/e2e/envelope-editor-v2/. Triggers include requests to "write an e2e test", "add a test for the envelope editor", "test envelope settings/recipients/fields/items/attachments", "fix a failing envelope test", or any task involving Playwright tests for the envelope editor feature.

Comfy-OrgSkill

reviewing-unit-tests

Comfy-Org/ComfyUI_frontend/.claude/skills/reviewing-unit-tests/SKILL.md

Use when reviewing Vitest unit-test diffs in ComfyUI_frontend, especially new mocks, store tests, component tests, or bugfix regression tests.

GitHubSkill

test-gap-audit

github/awesome-copilot/skills/test-gap-audit/SKILL.md

Run a read-only audit for missing, weak, stale, or mis-scoped test coverage. If the user does not name a scope, audit the full repository and identify important code paths, routes, features, services, workflows, and contracts that lack proper tests. If the user names a feature, PR, branch, route, workflow, service, bug fix, API, security-sensitive path, or risky code change, focus only on that specific scope. Use when the user asks what tests are missing, whether coverage is enough, what regression tests to add, or how to prove a change is safe. This is not a general bug audit and not a security review; it evaluates whether behavior is covered by tests.

perberSkill

tidy-tests

perber/leafwiki/.claude/skills/tidy-tests/SKILL.md

Restructure the tests of one LeafWiki package, file or feature for readability — split oversized test files by capability, turn copy-pasted cases into table-driven (matrix) tests, introduce a default fixture with overrides — without changing what is tested. Produces proof that no case and no coverage was lost. Use for dedicated test-cleanup PRs (e.g. "split router_test.go", "tidy the pages tests"); pass the package or file as argument.

cexllSkill

test-cases

cexll/myclaude/skills/test-cases/SKILL.md

This skill should be used when generating comprehensive test cases from PRD documents or user requirements. Triggers when users request test case generation, QA planning, test scenario creation, or need structured test documentation. Produces detailed test cases covering functional, edge case, error handling, and state transition scenarios.

MicrosoftSkill

test-analysis-extensions

microsoft/testfx/.agents/skills/test-analysis-extensions/SKILL.md

Provides file paths to language-specific reference files for the test ANALYSIS skills (assertion-quality, test-anti-patterns, test-gap-analysis, test-smell-detection, test-tagging). Call this skill to discover available extension files (e.g., dotnet.md for .NET/MSTest/xUnit/NUnit/TUnit, python.md for pytest/unittest, typescript.md for Jest/Vitest/Mocha, java.md for JUnit/TestNG, etc.). Do not use directly — invoked by the test-quality-auditor agent and polyglot analysis skills that need framework-specific lookup tables (test markers, assertion APIs, skip annotations, sleep patterns, mystery guest indicators, integration markers, setup/teardown, tag-support capability).

appsmithorgReads credentialsSkill

write-and-verify-pw-test

appsmithorg/appsmith/.agents/skills/write-and-verify-pw-test/SKILL.md

Write a Playwright E2E test from a prompt and verify it passes against a live Appsmith deployment. Configures environment variables, writes the spec following project conventions, runs it, and auto-fixes up to 3 times. Use when asked to "write a playwright test", "test this feature on a dp", "create and run an e2e test", or "verify this flow with playwright".

crbnosReads credentialsSkill

test

crbnos/carbon/.claude/skills/test/SKILL.md

Agentically test a specific feature end-to-end in the running Carbon dev server — analyze the branch diff (or a given feature/issue), build a test plan, drive the app with agent-browser, and cache successful playbooks to .ai/playbooks/ for reuse. Use to verify a feature or fix actually works in the browser ("test this", "verify in the browser", after /execute or /fix for user-facing changes). Builds on /auth and /error. For a broad does-everything-load sweep use /smoke-test.

OpenEMSSkill

oe-ui-test

OpenEMS/openems/.github/skills/oe-ui-test/SKILL.md

Use when writing or fixing Angular/Ionic UI tests in the OpenEMS UI (Karma/Jasmine), including formly view tests, chart tests, and component unit tests.

loft-shSkill

e2e-migration-validator

loft-sh/vcluster/.claude/skills/e2e-migration-validator/SKILL.md

Use this skill whenever a user wants to validate, review, or audit e2e tests that have been migrated from an old framework (typically in a `e2e/` directory) to the new `e2e/` framework. Triggers include: "review my migrated test", "validate this e2e test", "check my test migration", "did I migrate this correctly", "review e2e PR", "check test coverage after migration", or any request involving comparing old vs new e2e test files across the vcluster, vcluster-pro, or loft-enterprise repos. Always use this skill when an e2e test file or PR from one of these repos is provided for review — even if the user just says "take a look at this test".

assistant-uiSkill

test-quality

assistant-ui/assistant-ui/.claude/skills/test-quality/SKILL.md

Design and review meaningful tests for assistant-ui bug fixes, behavior changes, and pull requests that add, change, or remove tests. Use to choose test boundaries, prove regressions, and assess mocks and assertions. Editorial-only changes do not require new tests.

oxsecuritySkill

test

oxsecurity/megalinter/.claude/skills/test/SKILL.md

Build the MegaLinter Docker image and run the targeted linter tests to verify the implementation. Fourth step of the contribution workflow, use after /implement.

prestSkill

prest-integration-tests

prest/prest/.cursor/skills/prest-integration-tests/SKILL.md

Guides writing and reviewing pREST Docker/network integration tests under integration/ so each request is human-readable via step comments or table-driven descriptions. Use when adding or editing integration/**/*_test.go, HTTP controller E2E coverage, make test-integration, test-integration-postgres, test-integration-timescaledb, or when the user asks for integration tests.
