An Approach for Test Impact Analysis on the Integration Level in Java Programs

Test impact analysis is an approach to obtain a subset of tests impacted by code changes. This mainly applied unit testing where the link between and its associated easy obtain. On integration level, however, it not straightforward find such programmatically, especially when are held into separate repositories. We propose for selecting based on runtime changes reduce test execution overhead. provide set tools framework that can be plugged existing CI/CD pipelines. have evaluated range open-source Java programs found $$\approx $$ 50% reduction in average, above 80% few cases. also large-scale commercial system production similar results.
