Hosted by the Department of Homeland Security’s (DHS) Office of Accessible Systems and Technology (OAST), the Interagency Trusted Tester Program has created the following video series to explain and demonstrate how to use the Accessible Name & Description Inspector (ANDI) testing tool to inspect web pages for conformance with the Revised Section 508 Standards. The following video series is broken up into 18 parts, each aligned to a specific ANDI module.
Overview of the Accessible Name & Description Inspector (ANDI) tool, a web accessibility inspection tool, which performs single page testing to automatically detect accessibility issues.
Discover the features of the ANDI Graphics/Images module to test meaningful, decoratives, and background images for accessibility so the user has a text alternative that serves the equivalent purpose.
Understand how to use the ANDI Structures module to verify that the page content contains logical heading levels and the heading levels are programmed accurately, and to provide descriptive headings for content structure.
Discover how to use the ANDI Structures module to inspect visually apparent lists on the page to ensure the programmatic markup conveys the correct list type and list relationship in its structure.
Learn how to use the ANDI Structures module to identify the page’s primary human language and ensure it is programmatically identified to ensure that content developers provide information in the web page that user agents (e.g., browsers, assistive technology, operating systems) need to present text and other linguistic content correctly.
Understand how to use the ANDI Structures module to ensure that all written content, regardless of how many (human) languages are used, is programmatically identified correctly to ensure that user agents (e.g., browsers, assistive technology, software) can correctly present content written in multiple languages.
Discover how to use the ANDI Structures module to ensure that every web page contains a <title> element that will identify the purpose of the page to ensure it is distinguishable from other web pages.
Discover how to use the ANDI Color Contrast module to ensure that text has sufficient contrast with its background so that it can be read by people with moderately low vision (i.e. those who generally do not use contrast-enhancing assistive technology).
Learn how to use The Paciello Group’s Color Contrast Analyzer (CCA) to ensure the contrast ratio between text, and images of text, and it's background is sufficient. CCA is used to inspect color contrast when contrast cannot be programmatically identified by ANDI. Visit the Testing Tools for Web for download information.
