Datadog has introduced cross-browser testing support for Firefox, Chrome, and Microsoft Edge in its Synthetic Monitoring tool, with Internet Explorer 11 available in private beta. This feature allows users to create code-free end-to-end browser tests by recording user journeys and adding assertions. The multi-locator targeting algorithm ensures that the tests do not fail due to frontend changes. Cross-browser tests can be run automatically on a range of devices and in any environment, including CI pipelines, enabling teams to maintain consistent experiences for users across different browsers.
