Page Accessibility Validation

Accessible web pages are web pages that are designed in a way that people with disabilities or impairments can use them. Most US and EU organizations require accessibility compliance.

Using the Validate page accessibility step, you can check the accessibility level of your web page, while identifying elements in your web page that could have been made accessible, but were not. The accessibility checks are based on rules, which are listed here:

Accessibility Validation Support

Testim Accessibility steps use one of the leading accessibility libraries, Axe Core by Deque. Note that pure accessibility violations detected within the Accessibility step are primarily related to your application code. As such, addressing these specific issues falls outside the scope of Testim's support. If you encounter challenges in rectifying accessibility violations through code fixes, we advise you to seek assistance from Deque Axe-Core issues page. As accessibility experts, they can provide specialized guidance and solutions to address these issues effectively.

Adding a Validate page accessibility step

The Validate page accessibility step should be placed in the part of your test where the desired page to be tested is currently open in the AUT. If your test involves navigating to more than one page, be sure that the step is placed in the testing sequence where the desired page is open.
