Testing Accessibility with Style

What is HERA?

[ HERA | Help | Info | Code | Contact ]

HERA is a tool to check the accessibility of Web pages accoridng to the specification Web Content Accessibility Guidelines(WCAG 1.0). HERA performs a preliminary set of tests on the page and identifies any automatically detectable errors or checkpoints met, and which checkpoints need further manual verification.

Manual revision is always needed to test whether a page is accessible. To be able to do this testing it is normally necessary to know the Accessibility Guidelines, how users work with assistive technology, and have some practical understanding of web page design.

HERA assists in manual revision by highlighting the parts of the page that need checking, providing instructions on how to perform the tests, and offering two views of the page (normal page rendering and the HTML source code) with the most important elements for checking higlighted through colours and icons.

A form allows you to modify the results that were determined by automatic testing, add comments about each checkpoint, and give the name of the reviewer. It is also possible to generate a report for printing or to download in (XHTML, RDF / EARL and PDF) formats.

Important: The revision results are kept in the Sidar database for 7 (seven) days. During this time it is possible to continue the revision using the URI of the summary page, which contains an identifier for the particular revision.
