34. Accessibility automated tools - what to expect

3 October 2021

There are a few popular tools available for the accessibility testing such as Lighthouse, AXE Tool , and plugins.

Developers and Testers expect that these tools magically help them cover 100% accessibility issues. However, accessibility tools cannot provide you 100% cover from the issues but it can help you to atleast report some % of issues and how to fix them.

Today we are going to learn the issues automated took can and cannot report:

Common Tools

alt tagsCan identify if alt tags are missingCan't identify if alt tags are meaningful
LabelsCan identify if labels are missing & order is incorrect-
Color contrastCan identify if color contrast is failingCan't identify if color contrast on images and gradient
Focus-Can't identify if the focus order is correct
Order of HeadingsCan identify if order of H1-H6 is correct-
ARIACan identify if ARIA tag is missingCan't identify if the usage is correct
Role & landmarksCan identify if ARIA role and landmarks is missingCan't identify if the usage is correct
Semantic-Can't identify if the semantic tags are used or not
Responsive-Tools cannot identify if app is not responsive
Experience-Can't identify if the experience of assertive technologies is similar to non-assertive technologies

The above points are important to understand the scope of automated testing. While using the tools one should be aware 'what' the tools will be testing and do the manual testing of 'what cannot' be tested by tools.

Happy Learning!!
