Use ember-a11y-testing for Automated Checks

Integrate ember-a11y-testing into your test suite to automatically catch common accessibility violations during development. This addon uses axe-core to identify issues before they reach production.

Incorrect (no accessibility testing):

// tests/integration/components/user-form-test.js
import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render, fillIn, click } from '@ember/test-helpers';
import UserForm from 'my-app/components/user-form';

module('Integration | Component | user-form', function(hooks) {
  setupRenderingTest(hooks);

  test('it submits the form', async function(assert) {
    await render(<template><UserForm /></template>);
    await fillIn('input', 'John');
    await click('button');
    assert.ok(true);
  });
});```

**Correct (with a11y testing):**

```glimmer-js
// tests/integration/components/user-form-test.js
import { module, test } from 'qunit';
import { setupRenderingTest } from 'ember-qunit';
import { render, fillIn, click } from '@ember/test-helpers';
import a11yAudit from 'ember-a11y-testing/test-support/audit';
import UserForm from 'my-app/components/user-form';

module('Integration | Component | user-form', function(hooks) {
  setupRenderingTest(hooks);

  test('it submits the form', async function(assert) {
    await render(<template><UserForm /></template>);

    // Automatically checks for a11y violations
    await a11yAudit();

    await fillIn('input', 'John');
    await click('button');
    assert.ok(true);
  });
});```

**Setup (install and configure):**

```bash
ember install ember-a11y-testing

// tests/test-helper.js
import { setupGlobalA11yHooks } from 'ember-a11y-testing/test-support';

setupGlobalA11yHooks(); // Runs on every test automatically

ember-a11y-testing catches issues like missing labels, insufficient color contrast, invalid ARIA, and keyboard navigation problems automatically.
