Accessibility is more than a compliance requirement—it’s a powerful tool for creating resilient, reliable automated tests. Using NASA’s Open Mission Control Technologies (Open MCT) as a case study, this session will demonstrate how implementing accessibility standards not only improves usability but also strengthens test automation workflows. Attendees will see real-world examples of how traditional locators in Playwright can lead to brittle, flaky tests and how accessibility-driven development resolves these challenges. Through live demonstrations, including the use of a screen reader, we’ll explore the practical impact of semantic HTML, ARIA attributes, and focus management on both user experience and test stability. This session will provide actionable insights into incorporating accessibility standards into your applications, leveraging Playwright to write robust tests, and reducing test flakiness—all while making your applications more inclusive and user-friendly.
