e2e-tests

piskelapp/piskel/.claude/skills/e2e-tests/SKILL.md

MicrosoftSkill

test-tagging

microsoft/testfx/.agents/skills/test-tagging/SKILL.md

Classifies existing tests by standard traits and reports their distribution. USE FOR: tagging all tests with category attributes, categorizing/tagging/ labeling each test, compare happy vs error paths, audit the test mix, describe coverage shape by test type, or tag then verify the project builds. Read bodies when names mislead. Apply canonical attributes; otherwise report only. DO NOT USE FOR: requests owned by test-anti-patterns, coverage-analysis, crap-score, test-gap-analysis or code-testing. Framework/platform migration workflows are not installed in this repository and are outside this skill's scope.

manaflow-aiSkill

cmux-test-bisect

manaflow-ai/cmux/skills/cmux-test-bisect/SKILL.md

Find when and why tests broke on main: bisect a Swift package suite on CI across old commits, read the failure matrix, and decide per test whether the test went stale or the code regressed. Use when a suite is red on main, when PR CI only ran filtered tests and the full suite has drifted, or when asked which PR broke a test.

dotnetSkill

standalone-test-repro-method

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

Resolve a CoreCLR runtime test from a fully qualified method name for the standalone-test-repro workflow. Use for xUnit display names and methods in merged or multi-test assemblies, with or without a named test scenario. Continue with the parent standalone-test-repro skill after resolution.

ElasticSkill

BuilderIOSkill

test-audit

BuilderIO/agent-native/.agents/skills/test-audit/SKILL.md

Value bar for tests. Use when writing, changing, reviewing, or pruning tests: an authoring gate for new tests plus an audit workflow for low-value, implementation-coupled, or duplicative tests and the test-only production seams they keep alive.

VercelReads credentialsSkill

gate-tests

vercel/next.js/.agents/skills/gate-tests/SKILL.md

How to use the `@gate` / `@force-gate` test directives instead of `it.skip` or fake-green skip patterns. Use when a test is known-failing under some test-matrix dimension (dev mode, a bundler, an experimental flag like cacheComponents), when converting `if (isNextDev) return` guards or env-var `describe.skip` branches, when adding a condition to test/lib/gate/conditions.ts, or when keying a fixture's experimental flag on a __NEXT_TEST_AXIS letter. Covers directive choice, condition tiers, the test-axis fixture pattern, pitfalls, and verification commands.
