URL: https://github.com/apache/auron/issues/1654
**Is your feature request related to a problem? Please describe.**
+ Manually writing expected results is error-prone, hard to maintain, and
often breaks across spark versions duto to behavioral differences.
+ Many existing tests never verify the physical plan; in practice, a lot of
cases silently fallback to vanilla spark instead of executing with native
operators.
**Describe the solution you'd like**
+ Add `AuronQueryTest` extending `org.apache.spark.sql.QueryTest`
+ Provide helpers to:
+ Run a query once with native disabled to collect the baseline(vanilla
spark), then run with native enabled ans assert results match vanilla spark.
+ Optionally enforce that the physical plan contains only native
operators (ignoring stage/adapter nodes), failing fast otherwise.
**Describe alternatives you've considered**
