Review comment:
makes sense that functionally it will be the same after removing this
explicit setup.
i think we might want to explicitly set it so that this unit test does not
depend on the default value of `maxGeneratedCodeLength`, which hypothetically
can change, similarly to the test `testSelectExpressionWithSplitFromTable()`.
Plus, we don't have any perf issue adding this.
what do you think? i'm also okay to remove it if you see that's not an
issue, but think setting it explicitly is more robust.
