Aria semantics

As explained in React in Depth

An ARIA role is a semantic classification that describes how an element should be understood and interacted with by users and assistive technologies.

ARIA semantics classify elements by how users and assistive technologies should understand and interact with them. Roles make programmatic accessibility testable alongside visual behavior. section 10.1

Native elements expose useful roles automatically:

Testing a menu item

Render <MenuItem href="/blog" label="Blog" />, find the listitem and nested link by role, then verify the link’s href, title, and text content.

How React in Depth covers it

How deep it goes
Defines native roles and applies them in a focused test, but does not develop ARIA authoring rules or custom-role design.
Examples
Uses a MenuItem containing li and a elements, tested through listitem and link role queries.
What it assumes
Assumes familiarity with React components, JSX, and test assertions while explaining native roles from their usage.
What you can do after
Apply via React Testing Library by locating elements through roles and asserting accessible component behavior.
How it connects
Connects ARIA roles with accessibility, screen readers, semantic HTML, and React Testing Library queries.
