Selector.shadowRoot Method

Selects the shadow root hosted by an element.

selector.shadowRoot() → Selector

Use shadowRoot to access the element's shadow root. Returns null if the shadow DOM is not open.

Chain other Selector methods to it to traverse the shadow tree.

You cannot perform actions with a node returned by shadowRoot() or use it in assertions.

Only use this element as an entry point for shadow DOM.

The sample below shows how to identify a shadow root and access elements in the shadow tree.

import { Selector } from 'testcafe'

fixture `Target Shadow DOM elements`
    .page('https://devexpress.github.io/testcafe/example')

test('Get text within shadow tree', async t => {
    const shadowRoot = Selector('div').withAttribute('id', 'shadow-host').shadowRoot();
    const paragraph  = shadowRoot.child('p');

    await t.expect(paragraph.textContent).eql('This paragraph is in the shadow tree');

    await t.click(shadowRoot);
    // causes an error
    // do not target the shadow root directly or use it in assertions
});
