Which screen reader is NOT typically included in accessibility testing?

The correct answer is SAP because it is not a commonly recognized screen reader used in accessibility testing. JAWS, NVDA, and VoiceOver are widely acknowledged and utilized in the accessibility community for testing the usability of web content for individuals with visual impairments.

JAWS, developed for Windows, is one of the most popular commercial screen readers and is extensively used in professional environments. NVDA (NonVisual Desktop Access) is a free and open-source screen reader that is increasingly adopted due to its accessibility and effectiveness in various testing scenarios. VoiceOver, built into Apple devices, provides robust screen reader functionality for macOS and iOS users and is an essential tool for testing accessibility on Apple platforms.

In contrast, SAP (System Application Products) refers to enterprise application software and is not recognized as a screen reader. It does not serve the same purpose as JAWS, NVDA, or VoiceOver in enabling users to access digital content. Therefore, it would not be included in discussions or practices surrounding accessibility testing for web content.
