Hey
rymliam,
I've just had a look at Smart Assertion (ive only used it a couple of times), but i dont think it supports what youre looking for. Maybe one of the other forum members might be able to help instead.
However! Would you be open to using other assertion types like a script assertion? I use script assertions for the scenario youre talking about. If youre gonna use the script assertion option, youre gonna need to use xpath or jsonpath to assert the array contains the object content you want to verify is present.
If you dont want to use a script assertion, you could try using the contains assertion, but i think ita tailored for xml not json.
Cheers,
Rich
