CircleCI has enhanced its Insights dashboard by introducing Test Insights, which offers cloud customers detailed visibility into test performance, highlighting the most failed, slowest, and flakiest tests. This feature allows teams to analyze and optimize test performance within their development branches, providing an expanded lookback window and a high-level summary of test suite performance. Test Insights also includes flaky test detection, labeling tests that fail non-deterministically as "FLAKY" for easy identification. CircleCI plans to extend these capabilities to server customers and improve data lookback, flakiness detection, and test file aggregations. The company encourages user feedback to further refine the Insights feature.
