Split the monolithic GeneratedTests target (242 test classes) into 10 sharded targets with ~25 tests each to enable parallel test execution. Reduces test time from 85.4s to 36.7s (57% improvement) by running shards concurrently. Most shards finish in 2-8s with 2 outliers at 30-37s. The implementation automatically scales with new rules and provides parallel test execution with improved code maintainability.
