Generally, conformance testing includes three steps– preparation, evaluation, and reporting findings. The first step before you can start with the actual evaluation is to define the conformance level against which you are going to evaluate. The conformance level is given for each success criterion of WCAG 2.0 Guideline. Furthermore, it is important to specify the technical requirements for conducting the conformance test. That includes the combination of operating system, web browser, assistive technologies, browser plug-ins, and so forth. The next step is to select representative web pages, which will be the basis for the conformance test.

Our example includes only seven web pages and all are available from the home page, so it is easy to find your representatives. Other sites, such as Amazon, represent a broad variety of pages functionalities and designs. The following recommendation by the W3C helps to select a representative sample of web pages for the audit. Common web pages, typically– the home page and representative linked pages from the home page will be the starting point. Other web pages that are relevant for people with disabilities– for instance, pages describing the accessibility features on the target website, web pages reflecting essential functionalities, such as registration for an account. Diverse page– styles regarding forms, navigation and layout.

That means that you have to check all representative web pages against success criteria of the WCAG 2.0. The last step is to write a detailed report about the findings of the conformance evaluation. The report should include general information, such as name of the website, conformance level and technical requirements of the evaluation system. Furthermore, the report includes which success criteria were met and which were not. That is documented for each representative page. Finally, the findings are passed to the developer to improve the website accordingly.

How does conformance testing work?

Reading about conformance testing is not always easy as you have done completing the previous step. There are a myriad of documents and web pages to support the evaluation process and experts are always willing to help on accessibility forums.

This video goes through the process with step by step clarity. You may notice that the voice in the video sounds a little different. It is a text to speech voice - computer speech synthesis at its best with pauses and intonation responding to the punctuation used in a text document provided in addition to the slides. While the video refers to WCAG 2.0, it is also valid for the new version of the guidelines (2.1) which has added additional success criteria.
