Accessibility testing is a method used to check websites to ensure that content is accessible without relying on traditional ways of interaction (e.g., using a mouse, touchpad, reading content, etc.). It ensures that websites and apps can be used easily by everyone, including people with disabilities like vision or hearing problems, and other physical or cognitive issues.
Accessibility testing simplifies WCAG & ADA compliance through comprehensive scanning, including Full Page, Multi-Page, Partial Page, and Workflow scans. It improves accessibility by ensuring compatibility with screen readers, providing an automation SDK, and implementing regular monitoring schedules.
According to a global economics report, the estimated population of persons with impairments represents a market larger than China, controlling over $13 trillion. Ensuring apps are accessible can help organizations tap into this vast market.
Governments globally have laws mandating IT products be accessible to persons with disabilities. The W3C has created guidelines to ensure:
- Perceivable: Information must be understandable to all users (e.g., alternate text for images).
- Operable: Navigation must be accessible (e.g., keyboard, gesture, or voice navigation).
- Understandable: Content should be readable and understandable.
- Robust: Content must be robust across different devices and technologies.
88% of Americans with disabilities have access to the internet and digital devices. Organizations must ensure their web and mobile apps are accessible to support this group.
Removing barriers to access can increase customer base and improve reputation.
Designing accessible products leads to a better user experience for all.
- Functional Testing: Evaluate functionality with assistive technologies, such as screen readers and keyboard-only navigation.
- Usability Testing: Ensure products are easily understandable and usable, often involving feedback from people with disabilities.
- Compatibility Testing: Check compatibility with various devices, browsers, and assistive technologies.
- Performance Testing: Evaluate performance to ensure versatile usage, such as load time and responsiveness.
