Sets up testing frameworks, coverage tools, and sample tests for projects.
Does:
Does NOT:
| Technology | Test Framework | Coverage Tool | Config File |
|---|---|---|---|
| TypeScript/React | Vitest | v8/Istanbul | vitest.config.ts |
| .NET | xUnit | Coverlet | *.Tests.csproj |
| Python | pytest | pytest-cov | pytest.ini or pyproject.toml |
Before creating test infrastructure, check what exists.
Files to Check:
| Stack | Test Indicators |
|---|---|
| TypeScript | vitest.config.*, jest.config.*, *.test.ts, *.spec.ts |
| .NET | *.Tests.csproj, *.IntegrationTests.csproj |
| Python | pytest.ini, conftest.py, tests/, test_*.py |
Decision Logic:
Create vitest.config.ts:
Dependencies:
npm install -D vitest @vitest/coverage-v8 @testing-library/react @testing-library/jest-dom jsdom
Create test project:
dotnet new xunit -n {Project}.Tests
dotnet sln add tests/{Project}.Tests
Dependencies (in .csproj):
Add to pyproject.toml or create pytest.ini:
Dependencies:
pip install pytest pytest-cov pytest-asyncio
# OR with uv:
uv add --dev pytest pytest-cov pytest-asyncio

After setup, verify tests work.
TypeScript:
npm test
npm run test:coverage
Expected: Sample test passes, coverage report generated
.NET:
dotnet test
dotnet test --collect:"XPlat Code Coverage"
Expected: Sample test passes, coverage collected
Python:
pytest
pytest --cov=src --cov-report=term-missing
Expected: Sample test passes, coverage report shown
On Failure: Check test configuration, dependencies, verify sample test syntax.
| Metric | Minimum | Target |
|---|---|---|
| Lines | 70% | 80% |
| Branches | 70% | 80% |
| Functions | 70% | 80% |
| Statements | 70% | 80% |
Configure CI to fail if coverage drops below thresholds.
RULE 1: Coverage thresholds MUST be configured. No exceptions.
RULE 2: Sample tests MUST pass. Don't create broken examples.
RULE 3: Use AAA pattern (Arrange-Act-Assert) in all sample tests.
RULE 4: Co-locate unit tests with source (TypeScript) or use tests/ directory (.NET, Python).

概要と使いどころ
Design, implement, and audit inclusive digital products using WCAG 2.2 Level AA standards. Use this skill to generate semantic ARIA for Web and accessibility traits for Web and Native platforms (iOS/Android).

Whole site or product — a full web accessibility (a11y) audit against WCAG 2.2, following the WCAG-EM methodology. Defines scope, samples representative pages and flows, runs the automated tier (`accessibility-scan`) and the hands-on manual tier (`accessibility-inspect`), and produces one conformance report. Grades each finding by severity and evidence basis, and states per-criterion conformance as pass, fail, or undetermined (needs a human). Use it for 'audit my site for accessibility', 'is this product accessible', 'a11y audit', 'WCAG or Section 508 conformance report', or any multi-page assessment. Assesses; does not fix (use `accessibility-fix`) or diff (use `accessibility-diff`). For a single page use `accessibility-scan`; for hands-on keyboard and screen-reader checks use `accessibility-inspect`.

Regression check — diff a live page's web accessibility (a11y) violations against a baseline. By default it compares your uncommitted changes (stash-based); pass `--branch [<name>]` to compare against a branch. Reports the new WCAG violations introduced, the ones fixed, and the count of pre-existing ones. Use it for 'did my change break accessibility', 'what a11y issues did this PR add', or as a CI gate. For a full scan of one page use `accessibility-scan`; for a whole site use `accessibility-audit`.

Remediation only — repair web accessibility (a11y) violations against WCAG 2.2 with a baseline, edit, and verify loop. Takes a target (URL, files, directory) or a findings worklist from `accessibility-scan`/`accessibility-inspect`/`accessibility-audit`, applies mechanical fixes as given, leaves TODOs for visual or contextual judgment, and verifies by re-running the baseline check. It only fixes. To find issues use `accessibility-scan` (one page, automated), `accessibility-inspect` (one page, manual), or `accessibility-audit` (whole site, WCAG-EM); to check for regressions use `accessibility-diff`. Use it for 'fix the a11y issues in X', 'make this accessible', 'add missing alt text and labels', 'apply these accessibility fixes', 'remediate these violations'.

One page, hands-on manual tier — drive a live page through the web accessibility (a11y) checks a rule engine can't decide: keyboard operation and focus order, screen-reader names, roles and states from the accessibility tree, reflow and zoom, reduced motion, form errors, and target size. Grades each finding by evidence basis (verified / confirm-with-a-human / human-required) and severity, and closes every criterion in a ledger: verified, flagged, not exercised, or N/A. Locates and assesses; does not fix (use `accessibility-fix`). Use it for keyboard testing, focus-order checks, screen-reader or a11y-tree review, reflow and zoom at 200%, or 'is this operable, not just lint-clean'. The automated tier is `accessibility-scan`; `accessibility-audit` runs both across a sampled site.

One page, automated tier — run the web accessibility (a11y) rule engine against a live page and locate every violation it can detect mechanically. Pass a URL, a config target name (e.g. `accesslint:accessibility-scan dev`), or nothing to use the default target from `accesslint.config.json`. Ensures a debuggable Chrome, runs the @accesslint/core engine over CDP, and returns a worklist of live-DOM WCAG 2.2 violations, each grounded to its DOM selector and source `file:line`. Locates; doesn't edit. Use it for 'is this page accessible', 'check a11y on this URL', 'find contrast and alt-text issues', or to verify a UI change. For hands-on keyboard and screen-reader checks use `accessibility-inspect`; for a whole site or product use `accessibility-audit`; to diff against uncommitted changes or a branch use `accessibility-diff`.
