WAVE Evaluation Tool
The WAVE Evaluation Tool is a comprehensive web accessibility evaluation tool that helps developers and site owners identify and address web accessibility issues on their sites. Available as a browser extension for Chrome and Firefox, it provides visual feedback on the accessibility of web content by highlighting areas that need attention.
Axe Accessibility Checker
Axe is a powerful accessibility testing tool designed to work right in your web browser or as part of your testing pipeline. It’s capable of identifying accessibility issues with precision and without producing false positives. It's highly configurable and can be integrated into automated testing processes, making it an essential tool for developers committed to maintaining accessible websites.
JAWS Job Access With Speech
JAWS is a screen reader software designed to make content accessible to people who are blind or visually impaired. Familiarity with JAWS and testing websites or applications through it is crucial for developers to ensure their work is accessible to a significant user base, relying on voice commands and audio feedback to navigate and understand web content.
NVDA NonVisual Desktop Access
NVDA is a free and open-source screen reader for Windows that provides feedback via synthetic speech and Braille, making it another essential tool for web accessibility testing. It helps developers to understand how their websites or applications interact with assistive technologies, ensuring that they are usable by individuals with visual impairments.
VoiceOver
VoiceOver is a screen reader feature integrated into all macOS and iOS devices. It represents a significant portion of the market share among users who rely on screen readers. Testing web applications with VoiceOver enables developers to ensure compatibility and a seamless user experience on Apple devices, adhering to accessibility standards and guidelines.
Color Contrast Analyzer
This tool allows developers and designers to test the color contrast of text, graphical objects, and visual elements against the WCAG (Web Content Accessibility Guidelines). Ensuring sufficient contrast is crucial for users with visual impairments, including color blindness, and is a fundamental aspect of web accessibility.
Keyboard Accessibility Test Tools
Testing for keyboard accessibility is vital to ensure that users who cannot use a mouse can navigate and interact with web pages using keyboard inputs alone. Tools and approaches for this include using native browser capabilities to navigate the website without a mouse, ensuring all interactive elements are reachable and usable.
ARIA Accessible Rich Internet Applications Validator
ARIA Validator tools help in checking whether ARIA roles, properties, and states are correctly implemented in web content. Correct use of ARIA enhances accessibility for people with disabilities by providing more context to screen readers and other assistive technologies, making complex web applications more navigable and understandable.
Tenonio
Tenon.io is an accessibility analysis tool that offers an API for developers to integrate accessibility testing into development and deployment processes. It can test web content for accessibility issues in real-time, provide detailed feedback for remediation, and is adaptable to various development workflows, making it an excellent tool for teams looking to automate accessibility checks.
Lighthouse
Lighthouse is an open-source, automated tool for improving the quality of web pages, including their accessibility. It can be run against any web page, public or requiring authentication. Lighthouse audits web pages for accessibility, among other aspects like performance and SEO, providing clear and actionable reports that help developers improve their websites. It's integrated into Chrome DevTools, making it easily accessible for developers.
