Looking for Unit test for RPG programs/procedures

Hi all

I'm looking for a way to automate Unit test for RPG programs/procedures; i
try to better explain: until today when i write a new program o procedure,
to test it, i write a simple program that ask parameters to pass to the rpg
program or procedure , call program / procedure to test and then display the
result the program / procedure returns.

Question : does exist a similar utility / add on that make this
automatically ? i'm try to check if for example iRPGUnit, could do that
(ask parameters, call program and display result)

Any suggestione would be appreciated .

Thanks in advance
