  • Special keyboard designed for persons with motor control issues to make typing easier.

Furthermore, accessibility testing on humans with impairments offers beneficial information on the accessibility and usability of websites from their perspective.

Types of Accessibility Testing

Accessibility testing is a means of checking websites to ensure that material is accessible without relying on typical modes of interaction. It guarantees that websites and applications are easy to use for everyone, including those with impairments such as visual or hearing challenges, as well as other physical or cognitive issues.

Each method of testing has advantages, and combining different techniques is frequently the best way to ensure a thorough workflow in the process of the software development lifecycle. Accessibility tests can be conducted using functional, usability, compatibility, and performance testing methods.

  • Functional Testing

Functional testing is a sort of testing that determines whether each program feature meets the software requirements. Each function is compared to the associated requirement to determine whether its output matches the end user’s expectations. The testing is carried out by providing sample inputs, recording the results, and ensuring that the actual outputs match the intended outputs.

This sort of testing entails assessing the functionality of software delivery to guarantee that it is widely used by everyone. It entails testing the product, service, or environment using assistive devices such as screen readers, keyboard-only navigation, and actual persons with impairments.

  • Usability Testing

Usability testing is a technique for evaluating the functioning of a website, application, computer software, or other digital product by watching real users attempt to accomplish activities on it. Researchers working for a firm often study consumers during an in-person or, more commonly, remote usability testing session. This sort of testing involves assessing a product, service, or environment to verify that it is simple to comprehend and utilize. This may entail hiring persons with impairments to test the product and provide feedback on their experiences.

  • Compatibility Testing

Compatibility testing investigates and compares capability across numerous browsers, devices, platforms, and working systems to detect any differences. Browser compatibility testing guarantees that your product or software program operates properly in its intended environment. This sort of testing assesses the compatibility of a product, service, or surroundings with various devices, browsers, and assistive technology. This will entail testing the product on distinct operating structures, browsers, and cellular gadgets, as well as an expansion of assistive technologies.

  • Performance Testing

Performance testing is the process of determining how responsive and stable a system is under a certain workload. Performance tests are often used to assess speed, robustness, dependability, and application size. This sort of testing entails determining how well a product operates to ensure its versatility. It may also entail evaluating a website’s or application’s load time, as well as the responsiveness of devices and interfaces.
