Top Accessibility Testing Tools for Automation

In today’s article we are going to learn about most commonly used “Accessibility Testing Tools”.

Importance of Accessibility Testing

All application users cannot be alike and the application access cannot be limited to certain categories of users. Every software application is build for wide audiences and it also includes peoples with auditory, visuals, or other cognitive impairments. In order to involve all categories of people with a particular software application access, there is a need for application accessibility testing where application is tested from the point of view of end users where end users comprise of users with or without various cognitive impairments.

It is the governmental record from various countries that one in every five people possesses one or more type of cognitive impairments. Such Governments of many countries are taking initiatives and passing regulations to build software as well as amenities which could support people with various cognitive impairments.

Accessibility testing is a type of exploratory testing which is conducted with the help of people with various cognitive impairments who can provide their accessibility feedback, however we can also achieve full automation in accessibility testing with the help of the following accessibility testing tools.

It is an extension which helps to analyse the test color contrast on a particular web page as per the WCAG 2 text color contrast specifications. It can easily analyse gradients as well as CSS attributes on a web page. It provides the selective scanning of a web page section, tab, as well as entire web page for text color contrast against WCAG 2 specifications.

#9. Color Oracle

: It is a color simulator for Mac, Linux, and Windows. It helps to analyse the design suitable for color blind end users by showing in real time to the people with common color vision impairments.

#10. DOM Inspector

: It is an add-on available to Firefox web browser. It helps web developers to test and analyse what all DOM are truly accessible through “accessible tree” mode.

#11. Google’s Accessibility Test Framework for Android (GATF):

GATF is an accessibility testing tool which has in-built testing logic which can easily detect common accessibility issues. It can be easily integrated with other testing frameworks and tools. It uses Android UI constructs.

#12. Microsoft UI Automation tool:

It is an accessibility testing framework developed by Microsoft. It is used to test and automate windows application for user interfaces (UIs) against supplied programmatic information. It can be used to automate most of the UI present on windows desktop by using assistive technology products like screen radar which provide information about the UI accessible to end user. The tool enables tester to build automation test scripts in order to interact with the UI (User Interface).

#13. org:

It has lot of tools which can be used to automate specific type of accessibility testing. It supplies browser based interface as well as command line interface in order to run accessibility testing for sites and web services simultaneously.
