> Test sets for integration splits are
> [defined|https://github.com/apache/ozone/blob/50a547b8ee1c0ab72343498e94fa848005b73009/pom.xml#L2967-L3156]
> in Maven profiles, including and excluding tests based on package name.
> Theoretically, if only {{Test1}} in split A is changed by a commit, execution
> of splits B, C, etc. could be loaded from the cache. However, large modules
> (e.g. {{ozone-integration-test}}) have tests spread over multiple or even all
> splits. Test goals are executed per module, input includes all test classes
> from that module. Test filtering happens during execution, after cache
> lookup. Thus, changing {{Test1}} in split A causes cache miss for all splits.
> This could be improved by having each split cover one or more modules
> completely, and breaking {{ozone-integration-test}} into smaller modules (to
> spread tests more evenly).
