# Accessibility settings (/docs/e2e/conditions/accessibility)



`device.a11y` changes the system accessibility settings the app renders with, so a spec can check that a screen still fits at the largest text size or takes its reduced-motion path.

```ts
await device.a11y({ textSize: "accessibility-large", boldText: true, reduceMotion: true });
await app.open();
await device.a11y(null); // defaults back
```

| Option         | Takes                                                                           |
| -------------- | ------------------------------------------------------------------------------- |
| `textSize`     | a category (`extra-small` … `accessibility-extra-extra-extra-large`) or a scale |
| `boldText`     | boolean                                                                         |
| `contrast`     | `"increased"` or `"normal"`                                                     |
| `reduceMotion` | boolean                                                                         |
| `screenReader` | boolean                                                                         |

It returns `{ applied, skipped, notes }`. An option the platform cannot set is reported `skipped`; a call where every option is skipped throws `E_UNSUPPORTED`. Which platform takes which option: [Accessibility settings on a simulator](/docs/sims/conditions/accessibility#per-platform).

Auditing screens, reading order, announcements and driving TalkBack are in [Accessibility testing](/docs/e2e/accessibility).

## In a suite [#in-a-suite]

```ts title="warden.config.ts"
conditions: { a11y: { textSize: "accessibility-large", reduceMotion: true } },
```

The suite key takes `textSize`, `boldText`, `contrast` and `reduceMotion`.
