Navigating the World of Accessibility Testing – Part 1


In 2022, about 4.95 billion people worldwide were using the internet, which is roughly 62.5% of the world’s population. The internet has greatly impacted our lives by making information easily accessible. But does everyone have this access? Unfortunately, not.

Around 1 billion people have disabilities and can’t use the internet. Web accessibility ensures all can access the websites regardless of the disabilities. To ensure websites are accessible, we need accessibility testing.

Accessibility testing is assessing whether a software application, website, or digital content can be easily used by people with disabilities such as sensory, physical, cognitive, or developmental impairments. Mainly, it focuses on finding and removing any barriers in the application that might stop these individuals from accessing and using the digital product effectively.

By promoting inclusivity in the digital realm, accessibility testing encourages developers to embrace design approaches that cater to marginalized groups. This helps create a digital space where every user can actively participate and benefit from the available technology. Consequently, quality assurance professionals must integrate accessibility testing into their processes to ensure the presence of these inclusive features.

What is Accessibility Testing?

Accessibility Testing ensures that websites and apps are easy for everyone to use. It checks audio, visual, physical, neurological, and cognitive aspects to ensure every user can access them equally.

The process begins by assessing factors such as navigation for screen reader users and colour contrast ratios. These steps help people with vision problems and those who navigate with keyboards instead of mice. Accessibility testing aims to achieve the same goals, whether for mobile apps or websites.

Types of Accessibility Testing

1. Manual Testing

Human testers perform manual testing by interacting with the mobile or web app to find accessibility problems. They use assistive tools like screen readers to mimic users with disabilities. Testers explore the app, checking things like labels, keyboard use, and how easy it is to use. Manual testing finds small issues that automated tools might miss.

2. Automation Testing

Automation testing uses special tools to check web pages for accessibility issues automatically. These tools can look through lots of code quickly and find common problems, like missing descriptions for images or using headings wrong.

Automation testing is efficient for detecting known issues but may not catch all accessibility issues, especially those requiring human judgment.

3. Screen Reader Testing

Screen reader testing is part of manual testing. Testers look closely at how the app works when someone uses a screen reader. They ensure that all content is properly conveyed through audio cues, including accurate labeling of interactive elements and logical navigation order. This testing is very important. It makes sure people who can’t see well can still use the app easily.

4. Keyboard Navigation Testing

Keyboard navigation testing assesses how easy it is for people who only use keyboards, like those with physical disabilities, to use web and mobile apps. Testers make sure users can move around the app just using keys, not a mouse. They check the order keys work in, shortcuts, and if everything can be used with keys. This kind of testing makes sure people who can’t use a mouse because of physical issues can still use the app.

Importance of Accessibility Testing – Inclusive User Experience

The reason behind accessibility testing’s rising importance is a bigger push for inclusivity in making products. For example, in the car industry, manual gear shifts were mostly made for right-handed people, who are about 90% of the world. This left out left-handed people. But now, many car makers are changing to touch screens that anyone can use. It’s a move towards being more inclusive and thinking about users. This change explains the importance of accessibility testing in evaluating the quality of new technologies.

The software industry has undergone a similar transformation, with numerous technologies being developed to enhance accessibility. These technologies cater to various types of disabilities, including:

Visual Impairments:

  • Screen readers
  • Magnification software
  • Braille displays
  • Tactile graphics and interfaces

Motor or Mobility Impairments:

  • Keyboard accessibility with support for alternative input devices
  • Voice recognition and dictation software
  • Switch control

Hearing Impairments:

  • Closed captioning and subtitling
  • Transcripts for multimedia content
  • Visual alerts and notifications

Cognitive or Learning Disabilities:

  • Text-to-speech (TTS) software
  • Simplified and consistent user interfaces
  • Guided workflows and step-by-step instructions

Color Vision Deficiencies:

  • High-contrast color themes
  • Color blindness simulators

Speech Impairments:

  • Speech recognition and dictation software
  • Alternative communication devices and software (e.g., AAC devices)

Each of these technologies necessitates a unique approach to testing, leading to the establishment of a separate category for accessibility testing within the realm of software quality management. This specialized focus ensures that software products are accessible to individuals with diverse abilities, thereby fostering inclusivity and enhancing the overall user experience.


The Accessibility Testing Service Market is important for making digital spaces more inclusive. Trends like using AI and focusing on users highlight efforts to create digital places that everyone can use. As companies care more about accessibility, these trends will keep affecting the market. This ensures digital stuff isn’t just cool and new, but also usable by everyone. In a world where digital stuff is everywhere, following these trends isn’t just about business, but also about making a more inclusive future.
