open_shadow_dom

The command to open/expand a Shadow DOM element.

Syntax

Element.open_shadow_dom()

Usage

Shadow DOMs are a bit tricky because, like iframes, you need to "switch" to its context to find elements or objects within it. Check out this example using chrome://extensions:

def test_loading_extension_to_browser(py):
    py.visit('chrome://extensions/')
    shadow1 = py.get('extensions-manager').open_shadow_dom()
    shadow2 = shadow1.get('extensions-item-list').open_shadow_dom()
    extension_shadow_dom = shadow2.find('extensions-item')[1].open_shadow_dom()
    assert extension_shadow_dom.get('#name-and-version').should().contain_text('Get CRX')

Yields

• The Shadow Root (Element). With this element you can search for things within the Shadow context.
