Datadog CI Visibility provides insights into the performance of CI/CD pipelines and tests. It allows users to track the performance of their Cypress end-to-end tests using Real User Monitoring (RUM), enabling them to investigate flaky and failing tests, optimize slow tests, and troubleshoot performance gaps. With Datadog's tools, developers can gain deeper visibility into their test suites, identify bottlenecks in their application, and improve the quality and performance of their tests. The integration with RUM allows users to see how real users interact with their application during test runs, providing valuable context for debugging and optimization. By using CI Visibility and RUM together, developers can ensure that their tests are running efficiently and effectively, without sacrificing reliability or user experience.
