queryAllByRolelistitem

queryAllByRolelistitem is a function often found in testing libraries, particularly those designed for front-end JavaScript frameworks like React. Its primary purpose is to select all elements within a testing environment that have the ARIA (Accessible Rich Internet Applications) role of "listitem".

This function is a valuable tool for accessibility testing. By targeting elements with the "listitem" role, developers can ensure that lists in their applications are semantically marked up correctly. This semantic markup is crucial for assistive technologies, such as screen readers, to interpret the structure and content of lists accurately for users with disabilities.

When `queryAllByRolelistitem` is called, it searches the DOM for all elements that have been assigned the ARIA role "listitem". This role is typically applied to individual items within an unordered list (`<ul>`), an ordered list (`<ol>`), or a menu (`<menu>`). The function returns an array containing all the matching elements. If no elements with the "listitem" role are found, it returns an empty array.

Using `queryAllByRolelistitem` allows testers to verify the presence and number of list items, interact with them, or assert their content. This contributes to building more robust and accessible web applications by ensuring that list structures are correctly implemented and perceivable by all users.
