Web Accessibility Testing Key Features:

1. Contrasting color combinations: Webs’ text color and backdrop color should contrast well. Links, icons, buttons, and any other content on the page fall under this category.

2. Using Plain English in Writing: In the UK, 9 is the typical reading age in the UK. The most excellent way to ensure your material gets read by most people is to write it in simple, straightforward English. Fewer individuals can comprehend dense literature with jargon, acronyms, and sophisticated terminology. For those needing help understanding the implied meaning, metaphors and figures of speech can also be perplexing. Your content will be easier for everyone if you use plain English.

3. Videos with closed captions: All spoken words and audio in videos are described in closed captions. Closed captions and subtitles are frequently confused, but they differ somewhat. Similar to how subtitles offer a written alternative, closed captions also include additional pertinent audio from the video, such as “door knocks.”

Closed caption is an excellent example of an accessibility feature that benefits disabled and non-disabled users.

4. Navigation via keyboard only: A basic accessibility rule is ensuring your website is set up for keyboard-only navigation. Anyone who uses assistive technology, such as a screen reader, to browse websites is impacted. This covers various individuals with cognitive, sensory, or motor impairments.

Why Is Web Accessibility Important?

Web accessibility is important because the internet has to be accessible to everyone for individuals with impairments to have equal opportunities and access online the growing number of areas of our lives, including education, work, govt, business, medical services, entertainment, and more, rely on the Web and the Internet as a whole. Web accessibility helps people with disabilities participate more actively in society online.

Making your site accessible will ensure that most of your intended consumers those who are disabled—have a positive browsing experience and can quickly access your content. You may make the site user-friendly by applying accessibility best practices.

Additionally, having an accessible site is frequently one of the simplest methods to negotiate deals with several individuals with disabilities, such as those who struggle to read print, access physical stores or malls, and others. Additionally, the principles you employ for accessibility overlap with those for mobile Web design, accessibility, and SEO (SEO).

Ways to Perform Accessibility Testing:

There are several ways to perform accessibility testing using an automation testing tool like Testsigma:

  • Use the tool’s built-in accessibility checks: Many automation testing tools, including Testsigma, have built-in checks for common accessibility issues, such as missing alt tags for images and improper headings. These checks can be run automatically as part of the test plan, and any issues found can be reported for further review and resolution.
  • Use accessibility testing frameworks: There are several frameworks, such as aXe and WAVE, that can be integrated with automation testing tools to perform more comprehensive accessibility checks. These frameworks can check for various accessibility issues, including contrast ratios, proper use of ARIA attributes, and keyboard accessibility.
  • Use accessibility testing tools: There are also dedicated accessibility testing tools that can be used in conjunction with automation testing tools. These tools can provide more detailed information about the accessibility of a website or application, including any issues other methods may not catch.
  • Use manual testing: While automation testing is an important part of the accessibility testing process, it is also important to perform manual testing to ensure that the website or application is fully accessible. This can include testing with different assistive technologies, such as screen readers, and manually checking for issues such as keyboard accessibility and contrast ratios.

Overall, it is essential to use a combination of automation and manual testing to ensure that a website or application is fully accessible to all users. By using an automation testing tool like Testsigma, along with other accessibility testing tools and frameworks, organizations can ensure that their products are accessible and compliant with relevant standards and regulations.

Test Cases Accessibility Testing: Things to look at 

The following are a few things to look at when conducting this kind of testing:

  • Whether the labels are correctly positioned and written.
  • Whether or not the audio or video content is adequately audible or viewable.
  • Whether or not the color contrast ratio is maintained.
  • Whether or not the video controls function correctly.
  • If the menu has short keys available, you must ensure they are all functional.
  • It is necessary to check for tabs if switching between tabs is simple.
  • Whether or not the application complied with all the rules and regulations.
  • Whether the headline is original and conveys the structure and meaning.
  • If the link wording contains a content description rather than leaving room for uncertainty.

What are the types of accessibility testing?

There are four kinds of accessibility testing to provide accessibility for people of all abilities and keep up ADA compliance:

1. Automation of Testing: Begin with test automation, which rapidly reveals the easiest issues to fix and accessibility issues to improve. But since automated testing excludes interpretability and can overlook crucial accessibility concerns, it might not be sufficient to avert litigation or assist users of all abilities.

2. Reviewing manual codes: According to UsableNet, 100% of the recently modified WCAG 2.1 criteria for success and over 80% of the WCAG 2.0 standards call for manual assessment. The HTML, CSS, and Javascript are examined by real individuals with WCAG design review experience and knowledge to ensure they adhere to the standards.

3. User Testing: User testing allows actual users with disabilities, such as those who regularly use screen reader technology, to certify that your site is useable for them, as opposed to manual code review, which verifies that your site complies with WCAG.

4. Review of the user experience (UX): Examining larger site design components as part of a UX evaluation is necessary to check for accessibility and usability. The following aspects are examined during a UX review:

  • Visual structure 
  • Logical page layout 
  • Menu functioning 
  • Button size

People with low vision, mobility, or cognitive disabilities will find this method to be especially beneficial for native apps.

Conclusion

By ensuring that websites and web applications can be used by people with disabilities like hearing problems, eyesight problems, epilepsy, and cognitive impairments, web accessibility testing is a sort of software usability testing. Any software system’s accessibility should constantly be tested because it enables everyone to use the product, especially people with physical limitations.

Today, a significant portion of physically impaired persons use software products for their daily tasks, and accessibility testing tools enable websites to become more user-friendly. The accessibility testing tool you use should fit your site’s needs and budget.
