Explanation of accessibility testing (Digital Storytelling)
This page provides an explanation of Scottish Book Trust's approach to accessibility testing for this website.
For our annual audits, we use the Website Accessibility Conformance Evaluation Methodology (WCAG-EM) as a guide for defining the scope of our internal testing. We tested the Scottish Book Trust site against WCAG Version 2.1, conformance target AA.
We selected a representative sample of web content from the public website of Digital Storytelling located at https://www.digital-stories.scot(this link will open in a new window). This sample includes a minimum of one sample page from all main page types to test the website's full site functionality and range of content.
The page types selected for the testing sample are:
- Homepage
- About
- Our facilitators
- Macmillan video listing page
- Location video listing page
- Individual video page
Initially, we used WAVE Evaluation Tool browser extension to run automated checks of the pages selected for testing. WAVE checks pages against the WCAG 2.1 criteria, including A, AA and AAA conformance targets.
Some examples of automated checks carried out by WAVE include but are not limited to:
- Insufficient colour contrast
- Missing alternative descriptions on images
- Form field labels
Monitoring tools like WAVE can only find some accessibility issues, and human review is still necessary. Therefore, the selected pages were also checked using manual testing to ensure common issues related to automatic check errors were identified. For example:
- Ensure functionality is available to keyboard users
- Check if text should be marked as a heading
- Use of colour for meaning
- Relevant alternative descriptions on images, e.g. correctly defining images as decorative
- Ensure users can pause or hide animated content
Additionally, the representative sample of pages was also tested using screen reader technology. The screen reader and browser combinations used were NDVA and Firefox, Voiceover and Safari, and TalkBack and Chrome for Android. Screen reader testing was conducted using these combinations on both desktop and mobile devices.
