Version

1.45.0

Steps to reproduce

  1. Clone my repo at https://github.com/d4rky-pl/aria-disabled-repro
  2. Run npm install
  3. Run npx playwright test tests/aria-disable.spec.ts

Expected behavior

According to the documentation of toBeDisabled:

Ensures the Locator points to a disabled element. Element is disabled if it has "disabled" attribute or is disabled via 'aria-disabled'. Note that only native control elements such as HTML button, input, select, textarea, option, optgroup can be disabled by setting "disabled" attribute. "disabled" attribute on other elements is ignored by the browser.

Which sounds like the aria-disabled="true" attribute should be respected on all elements (and disabled attribute only on the listed ones). This is not the case here and both .click() ignores the attribute and .toBeDisabled treats this element as enabled.

Actual behavior

Either the behaviour should be fixed and elements with aria-disabled should be treated as disabled for all intents and purposes of what "disabled" means in Playwright, or the documentation should be adjusted to state clearly that disabled state is only supported for HTML form elements.

There is no indication on this <div> that it is in fact a button and that it is disabled. Playwright will do what the user would in this case - click the element.

@pavelfeldman if that's the intended behaviour then it's fine and this bug is just a documentation improvement request then 🙂

I ran into the same issue today. The toBeDisabled problem is solved by adding role="button" in the html element. Thanks for the nice repo @d4rky-pl!

@pavelfeldman I would love to send a PR but I'm going to need more details on what's the expected behaviour. When is aria-disabled taken into an account? What other attributes make Playwright consider it?

I have another example where toBeDisabled doesn't work. Here is the html:

<html lang="en">
<body>
  <label>
    <ul role="menu">
      <li role="menuitem" id="foo" aria-disabled="true">
        AAAAA
      </li>
    </ul>
  </label>
</body>
</html>

and here is the test:

test('aria-disabled is not ignored', async ({ page }) => {
  await page.goto('http://localhost:57487/tests/');
  await expect(page.locator('#foo')).toBeDisabled();
});

The error I got is:

Error: Timed out 5000ms waiting for expect(locator).toBeDisabled()

    Locator: locator('#foo')
    Expected: disabled
    Received: enabled
    Call log:
      - expect.toBeDisabled with timeout 5000ms
      - waiting for locator('#foo')
      -   locator resolved to <li id="foo" role="menuitem" aria-disabled="true">↵        AAAAA↵      </li>
      -   unexpected value "enabled"

Removing the label tag in the parent node solved the problem. I'd really like to know how this is supposed to work.
