Playwright Check Suites have been introduced as a solution to bridge the gap between testing and monitoring by leveraging the existing Playwright end-to-end test framework for synthetic monitoring. Traditionally, monitoring and testing have been handled separately, leading to inefficiencies, but Playwright Check Suites aim to integrate monitoring directly into developer workflows without requiring new tools or languages. This approach allows developers and QA engineers to transform their Playwright test suites into monitoring tools, enabling real-time validation of application flows in production environments. The integration offers features such as error alerts via channels like PagerDuty, detailed analysis of failed tests with videos and trace files, and the use of AI to analyze errors and provide insights into user impact and root causes. This unified approach promotes cross-team collaboration by allowing site-reliability engineers to use the same codebase for both testing and critical monitoring, ensuring that applications are continuously validated across global production environments.
