Hi,

I have a really simple function that allows or limits the access to a transaction for a client, depending on the kind of contract, kind of product, etc, etc.

The function receives the different types of product, etc, and compares them to constants, then returns on or off. Simple. There are about 10 different combinaisons that are restricted, all others pass ok.

My question is how to properly test that function? I could easily select clients with all prohibited contract types, products, etc, as these are only a few. How should I test all those types that are NOT prohibited?

Thanks.

How about a bit mask?

Each byte in a key value consists of a value related to one of the
attributes. Byte 1 could be contract, byte 2 product etc. At the end of
building the requirement, you'd end up with x'A02AB9884C' or something
like that. The attributes would need to be in a known order. Then you
just need to compare with a table containing the 10 forbidden
combinations and see if you have a match.
