When using select all, a status message is not given to the screen reader saying that all results are selected.
Expected: status should be provided to a screen reader.
Status message is not automatically announced by the screen reader.
Element Name: Status that appears on selecting 'Select all' Checkbox.
Location: In main region of the page, after
Clicking “Search” icon in left nav. Enter a search term like “Test”. Select Search and observe that a page that comes up, i.e. Search results with “grid view”.
NVDA is not narrating the status message that appears upon selecting 'Select all' checkbox
Recommendation to fix
Status messages MUST be programmatically determined through role or properties such that they can be presented to the user by assistive technologies without receiving focus.
HOW TO FIX:
Fix this issue by using an ARIA live region so screen readers can automatically announce the status message content.
<div aria-live="assertive">Your form was successfully submitted</div>
<div role="alert">Please correct the errors below to continue</div>
WCAG Understanding document: https://www.w3.org/WAI/WCAG21/Understanding/status-messages
When a status message is added to a webpage, screen reader users will likely not know about the message if focus is not moved to the message. Often it is not desirable to interrupt a user's workflow to move focus to a status message, so people who are blind must be alerted programmatically to the presence of the status message. When a programmatic means of identifying the presence of status messages is used, assistive technologies such as screen readers are able to alert users to the presence of the message.
NOTE: Status messages are defined as a change in content that is not a change of context (i.e. moving focus to a message) that provides information to the user on: 1) the success or results of an action ("Your form was successfully submitted"), 2) the loading state of an application ("processing your data request"), 3) the progress of a process ("50% complete"), or 4) the existence of errors ("Please correct the errors below to continue").
