Accessibility testing is a crucial aspect of software development, aimed at ensuring that applications are usable by all individuals, including those with impairments. This subset of usability testing, also known as 'a11y', strives to provide equal access to information and functionality, thereby maintaining a product's market share, enhancing usability, and preventing legal issues. Despite common misconceptions, creating accessible sites is neither costly nor slow and can be integrated into CI/CD processes. The significance of accessibility was underscored by a notable legal case where the US Supreme Court ruled in favor of a blind man against Domino's for site inaccessibility, prompting many companies to comply with accessibility guidelines like WCAG 2.0. These guidelines emphasize perceivability, operability, understanding, and robustness, and various tools and techniques exist to assist in meeting these standards. Furthermore, incorporating accessibility into daily development practices, such as creating user stories for sprints and using accessibility tools during code commits, can aid in maintaining compliance and ensuring that software is inclusive to all users.
