             Summary: Split up tests functions in ExprRewriteRulesTest for easier debugging
                 Key: IMPALA-7821
                 URL: https://issues.apache.org/jira/browse/IMPALA-7821
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 3.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers


Impala provides a single test class {{ExprRewriteRulesTest}} for all rewrite rules. Each rule class has an associated test function. Some rules are complex, and the result test functions are quite large.

When doing work to modify a particular conditional rewrite, it became clear that debugging would be much easier if each detailed rewrite had its own test rather than using one huge test function. This ticket asks to break up the big function. (JUnit does not care about small vs. large functions.)
