>                 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

> Simplification (from _RexSimplify_ class) is mostly covered is {_}RexProgramTest{_}, a test for 
> expressions of the form "IS NOT NULL(a) AND a=b" => "a=b" under the "UnknownAsFalse" semantics and not simplified under "UnknownAsUnknown" one, seems uncovered.
>  
> Since I had to write a test to make sure the simplification was as expected, I assume others might end up doing the same, and that the test will both act as documentation and it will also protect against regressions.
