<header>
descendant of <aside>
This test case is designed to determine how the <header>
element will be announced by various screen readers when it is a descendant of the <aside>
element.
In this case, the element should not be announced as a banner
landmark, as it is not scoped to the <body>
element, it is scoped to the <aside>
element
By default, the element being tested does not receive focus, so the only way to test how it is announced is via:
<aside>
<h4>Other content</h4>
<header>
<h4>Test content</h4>
</header>
</aside>
