Review Comment:
this is a legacy way of doing tests which is a way more limited ...
you can use a more modern way, for instance in `CollectionFunctionsITCase`
add a test for this function and among others have something like
```java
.testSqlRuntimeError("element(ARRAY[1, 2])", TableRuntimeException.class,
"Array has more than one element.")
```
this will test the change
