>             Project: Calcite
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 1.35.0
>            Reporter: Mihai Budiu
>            Assignee: Mihai Budiu
>            Priority: Major
>
> SqlOperatorTest has many tests, including end-to-end tests.
> However, none of these tests exercise the PROJECT_REDUCE_EXPRESSION rules, which often produce different results than these tests for constant expressions.
> Ideally we should be able to subclass SqlOperatorTest and use a fixture that also applies this optimization prior to evaluation.
> I have marked this as a {*}major priority{*}, because I suspect it would catch many bugs with minimal effort. (I have found at least 10 so far.)
