![Aria snapshots
New assertion `expect(locator).toMatchAriaSnapshot()` verifies page structure by comparing to an expected accessibility tree, represented as YAML.
```ts
await page.goto('https://playwright.dev');
await expect(page.locator('body')).toMatchAriaSnapshot(`
- banner:
- heading /Playwright enables reliable/ [level=1]
- link "Get started"
- link "Star microsoft/playwright on GitHub"
- main:
- img "Browsers (Chromium, Firefox, WebKit)"
- heading "Any browser • Any platform • One API"
`);
```
You can generate this assertion with Test Generator and update the expected snapshot with `--update-snapshots` command line flag.
