frontend-unit-testing

gradio-app/gradio/.agents/skills/frontend-unit-testing/SKILL.md

GitHubDeletes or force-pushesSkill

creating-oracle-to-postgres-migration-integration-tests

github/awesome-copilot/skills/creating-oracle-to-postgres-migration-integration-tests/SKILL.md

Creates integration test cases targeting Oracle for .NET data access artifacts. Tests capture Oracle expected behavior as the authoritative baseline; they are written once and later ported to PostgreSQL by migrating the test project in Phase 6. Use only during Phase 3, before any PostgreSQL migration work has begun. Do not invoke during Phase 6 or against a project that has already been migrated.

langflow-aiSkill

ibm-a11y-testing-guide

langflow-ai/langflow/.agents/skills/ibm-a11y-testing-guide/SKILL.md

Reference guide for writing and running Langflow frontend accessibility tests with axe (Jest) and IBM Equal Access (Playwright `page.runA11yScan`). Covers which engine/test layer to pick, the POUR checklist, axe-vs-IBM rule gaps, Radix/AG-Grid component gotchas, and IBM baselines. Use when writing or reviewing a11y tests, debugging a specific axe/IBM violation, or deciding which test layer fits a UI surface. Does not run scans, audit a whole surface, or fix a PR end-to-end — see ibm-a11y-route-scan, ibm-a11y-level1-audit, and ibm-a11y-pr-remediation for those.

open-aniSkill

datasource-test

open-ani/animeko/.agents/skills/datasource-test/SKILL.md

Test and debug an Animeko media source from its JSON config using the datasource-test-mcp HTTP MCP server. Validates selector config syntax offline, runs the real SelectorMediaSourceEngine pipeline (searchSubjects → selectSubjects → searchEpisodes → selectEpisodes → selectMedia) with per-step traces, iterates CSS selectors offline against saved HTML, tests matchVideo regexes, extracts real video URLs via CEF WebView, and probes actual playback with VLC. Use when asked to 测试数据源 / 调试 selector 配置 / verify a datasource JSON works / diagnose why a source finds no candidates for an episode or fails to play. Covers web-selector (CSS selector) sources in depth; other factories (rss/dmhy/mikan/jellyfin/...) via end-to-end testing. Also defines the capability-evolution (进化) loop: when a site is provably beyond current engine/WebVideoExtractor capabilities, write a capability-gap document and hand it to an isolated subagent that implements the new capability and outputs a git patch, then re-verify. Works exclusively through the `ani-datasource-test` HTTP MCP; it never starts the server itself — if that MCP is not configured the skill stops and tells the user how to add it. When a `chrome-devtools` MCP is also available, it is used as the real-browser ground truth (rendered DOM, real network requests, click interactions) to distinguish config mistakes from genuine engine/extractor capability gaps.

handsontableSkill

browserstack-live

handsontable/handsontable/.claude/skills/browserstack-live/SKILL.md

Use when testing a local or public URL on a real device via BrowserStack, opening a live browser session on Android, iOS, or desktop browsers, or when the user mentions BrowserStack, real device testing, mobile testing, cross-browser testing, touch testing, or wants to verify behavior on a specific phone, tablet, or browser version. Also trigger when the user says "test this on Android/iPhone/Safari/Chrome mobile", asks to open a live session, or mentions demo-mobile.html, even if they don't mention BrowserStack by name.

garrytanReads credentialsSkill

smoke-test

garrytan/gbrain/skills/smoke-test/SKILL.md

Health smoke tests + auto-fix for gbrain installs (and OpenClaw services when present). Run after machine/container restarts or whenever something seems broken. Tests critical services, auto-fixes bounded local issues, and reports worker topology without starting daemons. Extensible via user-defined test scripts in ~/.gbrain/smoke-tests.d/*.sh.

saleorSkill

pytest-runner

saleor/saleor/.claude/skills/pytest-runner/SKILL.md

Run pytest tests with automatic virtual environment activation. Use this skill whenever running tests, executing pytest, or when asked to "run tests", "test this", or any test execution task. Ensures venv is always activated before pytest runs.

googleapisSkill

fix-failing-tests

googleapis/mcp-toolbox/skills/maintainer/fix-failing-tests/SKILL.md

Diagnose a failing test in the googleapis/mcp-toolbox repo and land a fix by reasoning from the actual error: read the failure, reproduce it, shrink it until the cause is forced into the open, then fix the cause. Use this whenever a test or CI job is red, a build breaks after a change, many packages fail at once, or a test passes locally but fails in CI.

NangoHQSkill

running-tests

NangoHQ/nango/.agents/skills/running-tests/SKILL.md

Use when running tests in the Nango monorepo - knows unit vs integration configs, vitest commands, Docker setup, and common test patterns

QuivrHQ/quivr/.agents/skills/audit-tests-dev/SKILL.md

Invoke whenever writing, changing, reviewing, or sweeping tests.

mastra-aiReads credentialsSkill

testing-mastracode-tui

dotnetSkill

patch-il-baselines

dotnet/roslyn/.github/skills/patch-il-baselines/SKILL.md

Update expected IL baselines in compiler unit tests from Actual output for tests that are explicitly reported as failed. Use when Test Explorer or test output shows IL baseline differences and the requested fix is limited to those failed tests.

streamlitSkill

fixing-flaky-e2e-tests

streamlit/streamlit/.claude/skills/fixing-flaky-e2e-tests/SKILL.md

Diagnose and fix flaky Playwright e2e tests. Use when tests fail intermittently, show timeout errors, have snapshot mismatches, or exhibit browser-specific failures.

prowler-cloudSkill

pytest

prowler-cloud/prowler/skills/pytest/SKILL.md

SupabaseSkill

vitest

supabase/supabase/.agents/skills/vitest/SKILL.md

Vitest API and config reference (Jest-compatible) — mocking with vi.*, spies, fake timers, coverage configuration, fixtures, snapshots, and test filtering.
