Automate regression test triggering with AI
Blog post from CodeWords
Automating regression test triggering with AI can significantly improve the efficiency of continuous integration (CI) processes by selecting and running only the relevant tests based on code changes, rather than executing the entire test suite every time. According to the 2024 State of Testing Report by PractiTest, teams often spend a significant portion of their CI time on irrelevant tests. CodeWords offers a solution by analyzing code changes, mapping them to relevant test suites, and orchestrating the CI run while delivering AI-enhanced reports. This approach not only reduces CI time but also maintains confidence in catching regressions, as demonstrated by Google's Test Automation Platform, which achieved a 90% reduction in unnecessary test runs. The system employs static mapping, import graph analysis, and large language model (LLM) inference to ensure accurate test selection, and it intelligently handles flaky tests by tracking their flakiness score and automatically creating tickets for problematic tests. Enhanced test result reports provide actionable insights by explaining failures in the context of code changes, helping developers promptly address issues. This methodology is adaptable to various test frameworks and can be integrated into existing workflows to optimize test selection and execution in a scalable manner, ultimately reducing developer interruptions and CI costs.
