PostHogSkill

writing-tests

PostHog/posthog/.agents/skills/writing-tests/SKILL.md

Gates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before any change to what a pytest, Jest, or Playwright test asserts or sets up, down to one fixture or one assertion added to an existing block. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; extend the nearest existing test before writing a new standalone one; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network; no time bombs from absolute dates left to age against the real clock; no database a test never uses). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.

nasaSkill

fprime-component-integration-test

nasa/fprime/.github/skills/fprime-component-integration-test/SKILL.md

Integration testing phase of F Prime component development. Guides the agent through writing reusable pytest-based integration tests in the component's test/int/ folder using the GDS Integration Test API. These tests ship with the component and can be run against any deployment that includes it. Trigger when unit tests pass and the component is ready for integration testing. Keywords: F Prime, integration test, pytest, GDS, fprime_test_api, reusable test, component test.

ComposioHQSkill

python-testing

ComposioHQ/composio/.agents/skills/python-testing/SKILL.md

Select and run Python SDK verification with nox, Makefile targets, Ruff, mypy, pytest markers, sanity tests, type inference checks, and build checks. Use when adding Python tests, diagnosing Python CI, or validating Python SDK/provider changes. Do not use for TypeScript-only checks.

wekanSkill

meteor-testing

wekan/wekan/.agents/skills/meteor-testing/SKILL.md

Use when setting up, designing, writing, or repairing tests and test harnesses in a Meteor 3 app. Triggers on meteortesting:mocha, --driver-package, TEST_WATCH, TEST_BROWSER_DRIVER, MOCHA_GREP, meteor.testModule, focused tests, .only, Meteor.server.method_handlers, Meteor.server.publish_handlers, DDP.connect, --full-app integration mode, sinon, async test signatures, Playwright/Cypress E2E. Use this skill when the user asks about test runners, asks about testing publications, or asks about Jest vs Mocha in Meteor. For a failing, hanging, or flaky test whose failing layer or root cause is unknown, use meteor-debugging before changing the test or app.

handsontableSkill

visual-testing

handsontable/handsontable/.claude/skills/visual-testing/SKILL.md

Use when writing Playwright visual regression tests or adding a demo route for one - covers the decision rule (what earns a capture, and that a visual spec is in addition to a Playwright assertion), the custom tablePage fixture, the screenshot workflow, reg-suit comparison, and the demo routes in examples/next/visual-tests/

MicrosoftSkill

python-testing

microsoft/agent-framework/python/.github/skills/python-testing/SKILL.md

Guidelines for writing and running tests in the Agent Framework Python codebase. Use this when creating, modifying, or running tests.

dotnetSkill

review-testing

dotnet/orleans/.github/skills/review-testing/SKILL.md

Testing lens for Orleans — spec-derived oracles, example tests, Accordant model-based tests, CsCheck property-based tests, deterministic simulation with controlled time, fault injection, and Verify snapshots. Use during code review, and when planning or writing tests.

dotnetReads credentialsSkill

standalone-test-repro

dotnet/runtime/.github/skills/standalone-test-repro/SKILL.md

Generate a standalone console application under artifacts/tmp from a managed test under src/tests so it can be run directly with corerun. USE FOR: "create a standalone repro for this runtime test", converting a CoreCLR test wrapper path such as JIT/.../TestName.cmd into a console app, or extracting a fully qualified xUnit test method from a merged test assembly, including when a CI scenario such as jitstress1 is specified. DO NOT USE FOR: adding a regression test to src/tests, library tests under src/libraries, NativeAOT-only tests, or tests whose behavior fundamentally requires a native, browser, mobile, multi-process, or external-service harness.

moltbotSkill

openclaw-testing

moltbot/clawdbot/.agents/skills/openclaw-testing/SKILL.md

Choose proportional OpenClaw tests/checks, diagnose failures, route environment-sensitive or release proof to its owner.

esphomeSkill

component-tests

esphome/esphome/.agents/skills/component-tests/SKILL.md

Write and run tests for ESPHome components - YAML build tests (test.*.yaml, validate.*.yaml, common.yaml) under tests/components, shared bus packages and CI test grouping, C++ gtest unit tests, and host integration tests including the uart_mock fixture. Use when adding or changing files under tests/, or when a code change needs test coverage.

dotnetSkill

verify-tests-fail-without-fix

dotnet/maui/.github/skills/verify-tests-fail-without-fix/SKILL.md

Verifies tests catch the bug. Auto-detects test type (UI tests, device tests, unit tests) and dispatches to the appropriate runner. Supports two modes - verify failure only (test creation) or full verification (test + fix validation).

udecodeSkill

test-audit

udecode/plate/.agents/skills/test-audit/SKILL.md

Audit existing tests for low-value, duplicated or implementation-coupled cases and the test-only code they keep alive, then remove or rewrite them on evidence. /test-audit full covers the whole suite and also lists public contracts no test guards. Use for test-audit, /test-audit <scope>, /test-audit full, a test sweep, or pruning tests. Not for writing a new test; the project's Tests rule gates that.

JeffallanSkill

playwright-expert

Jeffallan/claude-skills/skills/playwright-expert/SKILL.md

Use when writing E2E tests with Playwright, setting up test infrastructure, or debugging flaky browser tests. Invoke to write test scripts, create page objects, configure test fixtures, set up reporters, add CI integration, implement API mocking, or perform visual regression testing. Trigger terms: Playwright, E2E test, end-to-end, browser testing, automation, UI testing, visual testing, Page Object Model, test flakiness.

pnpmSkill

testing-changes

pnpm/pnpm/.agents/skills/testing-changes/SKILL.md

Run the tests that cover a change in the pnpm repository, in the Rust workspace (pnpm/, pnpr/) or the TypeScript CLI (pnpm11/), and recognize the cases where a scoped run passes without testing anything. Use whenever verifying a change before committing or pushing, or when deciding what to run after an edit.

moeru-aiSkill

vue-testing-best-practices

moeru-ai/airi/.agents/skills/vue-testing-best-practices/SKILL.md

Use for Vue.js testing. Covers Vitest, Vue Test Utils, component testing, mocking, testing patterns, and Playwright for E2E testing.

remix-runSkill

write-tests

remix-run/remix/.agents/skills/write-tests/SKILL.md

grafanaSkill

frontend-testing-strategy

grafana/grafana/.claude/skills/frontend-testing-strategy/SKILL.md

Write and run unit and E2E tests for Grafana frontend code (React/TypeScript, any package or feature area) to the conventions this repo expects. Use when running Playwright E2E tests; when adding, backfilling, or reviewing frontend tests; when a test only asserts "it rendered" or "it's defined"; when reviewing AI-generated tests for slop; or when a frontend test is flaky. For visualization panels and grafana-ui viz components specifically, also load the `panel-testing-strategy` skill.
