As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In order for us to advise you, inform us of the functions of testing the insurance software. Is that software designed only for insurance or can it be used for some other purposes?
Will you have to make some recommendations to the software company to be able to use the software? If so, what would those recommendations be?
