Summary

Flaky tests, which unpredictably fail and succeed on subsequent runs, are a common issue in the software industry, significantly affecting productivity and costing companies over time. Notably, a 2022 survey reported that companies like Google and Microsoft experience a high percentage of flaky tests, which often lead to manual restarts of failed jobs in continuous integration (CI) environments. To address this problem, Hemanth Sridhar suggests utilizing TestNG's failed tests feature and Harness's Retry failure strategy to create a pipeline for managing flaky tests. This involves running an initial suite of tests, identifying failures with a testng-failed.xml file, and employing a retry mechanism with specific parameters such as retry count and intervals to attempt passing the failed tests again, marking the overall pipeline status based on the final outcomes. Sridhar's approach emphasizes structured retries to improve CI efficiency and reduce the impact of test flakiness on software releases.
