I have an API in Postman that has defined JSON schemas for every request\response. I also have a collection of tests that i use for testing this API. But I don't know how to connect these two substances(things) I have been searching for a solution for quite a while now and havent found an example set-up or a tutorial how? instead of creating a variable with actual schema in my test collection, I want to reuse already existing schema from API by $ref or some other link method.
This is my first question here, writing it just cause i haven't found a proper answer but functionality that i seek sounds really basic and logical.
