> Add test for 'a IS NOT NULL AND a = b' simplification
> -----------------------------------------------------
>
> Key: CALCITE-4917
> URL: https://issues.apache.org/jira/browse/CALCITE-4917
> Project: Calcite
> Issue Type: Test
> Components: core
> Affects Versions: 1.28.0
> Reporter: Alessandro Solimando
> Assignee: Alessandro Solimando
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 2h 40m
> Remaining Estimate: 0h
>
> Simplification (from _RexSimplify_ class) is mostly covered in
> {_}RexProgramTest{_}, but tests for expressions of the form "IS NOT NULL(a)
> AND a=b" (with nullable and not nullable types) seem to be missing.
>
> Since I had to write tests to make sure the simplification was as expected, I
> assume others might end up doing the same, and that the tests will both act
> as documentation and it will also protect against regressions.
