Types Of Accessibility Testing

Manual accessibility testing:

In this accessibility testing method, testers with WCAG technical review knowledge and expertise review the web. Testers manually test all scenarios and identify all non-conformances with respect to WCAG guidelines.

Automation Accessibility Testing:

In this testing technique, testers leverage automated accessibility testing tools to test the accessibility of the web. It helps identify accessibility issues faster and with less effort than manual accessibility testing.

Native and hybrid mobile apps accessibility testing:

This testing method involves accessibility testing of all native and hybrid mobile apps. This testing method tests all accessibility scenarios for android and iOS apps.

Web app accessibility testing:

In this testing method, the testers evaluate the accessibility of web apps by checking various aspects of web content, such as content readability, images, color contrast, etc.

508 Compliance testing:

In this method, testers check whether an app fulfills the standards mentioned under the 508 compliance act. Testers check various aspects of an app, like text equivalents for every essential photo, image, logo, or other non-text elements.

Hardware accessibility testing:

This method involves conducting an in-depth evaluation of the product’s hardware accessibility to ensure conformance with section 508 and other standards. This ensures that the product hardware is accessible to all, including people with specific disabilities.

How to Create Effective Test Cases for Accessibility?

Web applications and software should be designed to cater to a diverse audience, including people with disabilities. Ensuring accessibility isn’t just a one-time task; it requires ongoing efforts, with one crucial aspect being creating effective test cases. Let’s take a look at how to develop effective test cases for accessibility:

To start creating impactful test cases, it’s necessary to grasp the fundamental accessibility guidelines. Familiarize yourself with established standards such as the Web Content Accessibility Guidelines (WCAG). These guidelines provide a solid foundation, helping you comprehend the principles of accessibility and pinpoint potential areas for improvement.

Effective test cases are born from collaboration. Engage a diverse group of experts, including accessibility specialists, developers, designers, and testers. This multi-disciplinary approach ensures that every facet of your product is thoroughly examined from different perspectives, enriching the quality of your test cases.

Ambiguity has no place in creating accessibility test cases. Clearly convey what success looks like for each test case. For instance, rather than saying, “The page should be navigable,” specify “, The page must be navigable using keyboard navigation alone, with clear focus indicators at all times.”

Accessibility encompasses a broad spectrum of disabilities. Your test cases should comprehensively address various scenarios, including visual, auditory, cognitive, and motor impairments. For example, test for proper screen reader compatibility, keyboard navigation, high contrast options, and video captioning.

Effective test cases simulate real-world situations. Consider the different devices, browsers, and assistive technologies your users might employ. For example, ensure your test cases cover scenarios like using a screen reader on a mobile device with different orientations.

Users engage with your product in diverse ways. Mapping out different user journeys is crucial. For instance, test the accessibility of a checkout process for an e-commerce site, ensuring that users with disabilities can seamlessly complete a purchase.

Don’t focus on positive scenarios, as negative testing is equally vital. Craft test cases that explore failure points. For instance, test how your application handles form validation errors for users who rely on screen readers.

Edge cases hold valuable insights when testing for situations that might be less common but can still impact users with disabilities. For instance, examine how your application handles sudden font size changes or interruptions in assistive technology usage.

Test automation can significantly speed up the testing process. However, not all accessibility issues can be detected through automated tools alone. Utilize automation to cover the basics, but cover it with manual testing to catch minor errors and bugs.

Documenting your test cases in detail is essential. It not only aids in the testing process but also serves as a knowledge repository for future projects. Moreover, accessibility is an ongoing journey. Regularly revisit and refine your test cases to adapt to evolving standards and technologies.

What is Website Accessibility?

Website accessibility is most important today for businesses as the web and mobile mediums continue to have surge in their usage by people of all ages. Accessibility is truly no longer optional and is rather a mandate for businesses to follow for their websites and apps. This ensures people with disabilities such as color blindness, hearing impairment, cognitive disabilities, etc. to access the services, features and content on the web and also on the mobile apps.

According to Ontario.ca, “Beginning January 1, 2021: all public websites and web content posted after January 1, 2012 must meet WCAG 2.0 Level AA other than criteria 1.2.4 (live captions) and 1.2.5 (pre-recorded audio descriptions).” It is rather a compliance as it is necessary for the people with disabilities to be able to access website content which includes any information that is found on the web page or web app, including text, images, forms and even sounds.

What does WCAG compliance stand for?

WCAG (Web Content Accessibility Guidelines) guidelines are internationally accepted standards for web accessibility and have been developed by World Wide Web (WWW) team of experts.  These guidelines define how to make web content accessible to people with disabilities including visual, auditory, physical, speech, cognitive, language, learning and for people with neurological disabilities.

WCAG 2.0

WCAG 2.0 is categorized into 3 levels of conformance with A the lowest level, AA as mid-range and AAA as the highest level. It is a mandate today that web accessibility is primarily considered as a priority for all digital projects and should be made complaint with these much essential guidelines.

This compliance has been clearly mentioned in a Forbes article on Website Accessibility, which states that individuals with disabilities represent a large portion of the population.

In real sense, the website accessibility refers to the process of making the web accessible to all people or to everyone irrespective of their disabilities to ensure they can also make use of all/most of features of the applications.

In another study, researchers found that 71% of individuals with disabilities will abandon a website that’s difficult to use. This results in an estimated loss of £11.75 billion (or approximately $14.4 billion) each year in the United Kingdom alone.

How do you get your websites and web apps become accessible to all?

It is a prime social responsibility for organizations and businesses to ensure your applications are accessible to differently abled population. Organizations can become WCAG complaint by adopting web accessibility testing to standardize their applications accessibility for impaired vision, color blindness, blindness, deafness, hard-of-hearing, moto impairment, mobility impairment, etc.

Another data from the U.S. Census Bureau reveals that nearly one in five people are living with a diagnosed disability, and more than half of those with a disability describe their condition as severe.

Primarily, there is a compliance involved in this accessibility as when companies deny equal access of their website or when their website becomes incompatible with a screen reader or has any other accessibility issues, then such companies become liable to law suits.

Web Accessibility Testing Benefits for your Websites and Apps

Ensures people with disabilities to quick and easy access:

The most important benefit with accessibility testing is that it ensures the website content, product, services and all features are easily accessible to people with disabilities.

Enables an opportunity to expand your user base:

With an improved website and mobile app access, it definitely leads to an increase in the number of users accessing your website. Specifically, for such highly accessible websites, everyone irrespective of their disabilities can access such websites and perform their operations in a simple and easy way. According to an article by Bureau of Internet Accessibility, disabilities come in many different forms, including hearing disabilities, visual disabilities, motor disabilities, and cognitive disabilities. The U.S. Centers for Disease Control and Prevention (CDC) estimate that 1 in 4 U.S. adults is living with a disability.

Facilitates to build positive brand response:

If your website becomes WCAG accessibility compliant, then people with some or the other disabilities would use these fully complaint websites and apps. They would also recommend your brand to other acquaintances, their friends and other connections. In this way there is more chance for improving your brand visibility and this sort of good brand building would be more profitable for eCommerce sites.

Helps improve usability for visitors of all types:

Many usability problems of various users can also be identified with accessibility testing and it makes easier access of content, features, products and services of the website and mobile apps to various types of users who visit such websites.

Helps improve search engine optimization:

Another remarkable benefit with web accessibility testing is that if the website is accessible, then it makes the website more usable. It is also more likely to improve the website rankings and is bound to drive more traffic with higher SEO rankings.

Ensures to avoid legal complications:

Though most businesses are not intentionally discriminating disabled people, but they can be subject to legal complications with respect to web accessibility. But, if your website is WCAG compliant, then you can avoid any further legal complications.

Conclusion

Web accessibility has become a norm for businesses in the recent times and they should make their websites and applications WCAG complaint.
