How to unit test pl/sql collection in the unit test ?

Question

There is a function SPLIT_LIST (see below) to split a string list to a collection type .
I'm trying to use the SQLP DEVELOPER to do the unit test on this fucntion. The idea is to use lookups to give multiple string list for different inputs such as 'A,B,C' 'D', '', 'EF,,GH'. for multiple tests a time.
the expected result (function returns) are SPLIT_TBL('A','B',C'), SPLIT_TBL('D'), SPLIT_TBL(), SPLIT_TBL('EF','','GH')
But I have problem to use unit test to verify the result based on the lookups as the out put is the collection. anyone has a good idea to do those ?
create or replace TYPE SPLIT_TBL AS TABLE OF VARCHAR2(32767) ;
create or replace
FUNCTION SPLIT_LIST (
P_LIST VARCHAR2,
P_DEL VARCHAR2 DEFAULT ' ' )
RETURN SPLIT_TBL PIPELINED DETERMINISTIC
IS
lv_idx PLS_INTEGER;
lv_list VARCHAR2(32767) := P_LIST;
lv_value VARCHAR2(32767);
BEGIN
LOOP
lv_idx := instr(lv_list,p_del);
IF lv_idx > 0 THEN
PIPE ROW(SUBSTR(lv_list,1,lv_idx-1));
lv_list := SUBSTR(lv_list,lv_idx+LENGTH(p_del));
ELSE
PIPE ROW(lv_list);
EXIT;
END IF;
END LOOP;
RETURN;
END;

I'm having a similar problem - have you solved yours yet?
As for me, when I return a collection as an output parameter from a procedure, I can't test the result.
Example: I'm testing a procedure defined like this: Procedure check_this (p_id number, p_result out CompResult)
where CompResult is defined as: create or replace type CompResult is varray(100) of CompObj;
Unit Test understands that the data type of out parameter p_result is CompResult.
It fills in schemaName.CompResult() as the result (empty varray).
Editing of the result does not appear to be allowed - it's read only.
So, when the proc returns a varray that isn't empty, the test fails.
