Hi, https://issues.apache.org/jira/browse/IMPALA-5078
I'd like to get your advice if I will refactor expr-test.cc. Henry suggests grouping tests by string instructions and move them to expr-string-test.cc. I like his idea. You know filenames (e.g. cast-functions*, timestamp-functions*, aggregate-functions*) of backend kernel code in exprs have a same pattern, so I would suggest a pair of kernel code and unit test. For example, (cast-functions*, expr-cast-test.cc), (timestamp-functions*, expr-timestamp-test.cc), (aggregate-functions*, expr-aggregate-test.cc), ... Do you have any suggestion or comment on this? Thanks. Best regards, Jinchul
