This post explores how to perform automated accessibility checks using Playwright and Checkly, leveraging the power of the axe-core library. Automated accessibility testing empowers developers to take responsibility for most accessibility issues without needing specialized expertise, allowing development teams to allocate expert resources more efficiently. Axe is a comprehensive accessibility testing engine designed for websites and HTML-based user interfaces, facilitating automation alongside routine functional testing. The integration of axe-core with Playwright tests enables developers to run accessibility checks in a streamlined manner, improving test readability and configuration. Additionally, integrating with Checkly's synthetic monitoring allows for continuous monitoring of web application accessibility, ensuring that new or existing content does not introduce accessibility issues.
