Curated HTML fixtures + golden snapshots for accessibility rule testing.

HTML fixtures are dedicated to the public domain under CC0-1.0 (Creative Commons Zero v1.0 Universal — maximum-permissive, no attribution required). The fixture-server source code under src/serve.ts remains EUPL-1.2 and carries an inline EUPL-1.2 SPDX header. The compound SPDX expression in package.json is CC0-1.0 AND EUPL-1.2.

What this package does

Provides a stable, version-controlled set of HTML test inputs for accessibility-rule libraries, scanners, and CI harnesses. Two layers:

• Generic axe-core cases — minimal stand-alone files for basic regression: contrast violations, missing alt, iframe / shadow-DOM containment, mixed-severity baselines.
• EU real-world patterns — fixtures that imitate the visual / interaction patterns of widely-deployed European services (Klarna-style SE checkout, BankID-style SE authentication, MobilePay-style DK merchant flow, Finnish DOS-lagen statement, German Mittelstand, French RGAA). No third-party brand assets are embedded; brand names appear only in filenames and provenance comments for findability.

Install

npm install --save-dev @ariada-org/test-fixtures

Usage — programmatic HTTP server (generic fixtures)

import { startFixtureServer } from "@ariada-org/test-fixtures";

const fx = await startFixtureServer();
// fx.url → http://127.0.0.1:<random>
// navigate to `${fx.url}/color-contrast.html` etc
await fx.stop();

Usage — file-path access (any fixture)

import { createRequire } from "node:module";
import * as path from "node:path";

const require = createRequire(import.meta.url);
const fixturesRoot = path.dirname(
  require.resolve("@ariada-org/test-fixtures/fixtures/basic-pass.html"),
);

// or for the EU real-world set:
const euRoot = path.dirname(
  require.resolve("@ariada-org/test-fixtures/fixtures/eu-real-world/README.md"),
);

Generic fixtures (fixtures/)

| File | Purpose | | --------------------- | --------------------------------------------- | | basic-pass.html | Clean baseline, no violations | | color-contrast.html | 2 critical-contrast violations | | alt-text.html | 3 serious missing-alt violations | | shadow-dom.html | Open shadow root with inner violations | | iframe-nested.html | Top frame + same-origin child with violations | | iframe-child.html | Child of iframe-nested.html | | mixed-severity.html | Mixed critical/serious/moderate/minor |

EU real-world fixtures (fixtures/eu-real-world/)

Each file carries an in-file License: CC0-1.0 header and a Status: PASS|FAIL|MIXED marker. Categories:

• Danish mobile pay — mobilepay-style-{merchant-checkout,authentication,bad-merchant}-da.html

License

CC0-1.0 for all fixtures/** HTML content (Creative Commons Zero — public-domain dedication, maximum-permissive). EUPL-1.2 for src/serve.ts (the in-process fixture-server code). REUSE-machine-readable metadata in REUSE.toml. See NOTICE for the patent-peace pledge and trademark notice.

The CC0-1.0 dedication on fixtures is deliberate: accessibility test corpora benefit from frictionless reuse across competing toolchains, regulators, and academic work. We chose CC0-1.0 over Apache-2.0 / MIT to avoid an attribution-collision problem when downstream consumers concatenate fixtures from multiple sources into a single golden-file suite. This also aligns with Horizon Europe Article 17 «open data» principles for publicly-funded research outputs.
