arXiv:2606.11132v2 Announce Type: replace Abstract: Data-intensive computing frameworks such as Apache Spark and Flink keep expanding their APIs with new data types, expressions, and operators. Their most damaging bugs return silently wrong results rather than crashing, which tools that detect only crashes or exceptions cannot see. Property-based testing can catch such bugs, but only if someone writes a property with a strong oracle, and writing properties one API at a time cannot keep pace with this growth. We observe that many such properties are instances of a few textbook principles: congruence of equivalent expressions, relational-algebra equivalences, and aggregate decomposition. Each principle holds not only for an isolated operator but also for any workload built around it. We present Holey, which introduces meta-properties: properties with holes. A meta-property fixes how a workload is transformed and which relation its outputs must satisfy, but leaves open the expressions or operators being related. A developer fills the holes with a short binding. Holey then turns the resulting concrete property into many executable tests by generating schema-valid multi-stage workloads and input data around it. Each meta-property has a typing rule over its holes. A binding is checked once against this rule, and we prove that every test generated from a type-correct binding is schema-valid. Seven meta-properties yield 207 concrete properties, with bindings averaging under 20 lines. Holey found 17 previously unknown wrong-result bugs in the latest releases of Spark and Flink, 9 of which need relations that existing SQL testing oracles such as TLP and NoREC do not state, and its meta-properties express 55 of 65 testable historical Spark correctness issues. Its generated workloads cover 1.9x the branches covered by CometFuzz.
