04/24/2023, 1:29 PMHi, I already wrote in the pact-jvm channel, but I guess it's also a general question, so I'm trying here as well. I am looking for a way to specify that we expect either attribute A to be present, OR attribute B. Is there a way to specify this with pact? I have tried with the combine : "OR", but I suspect this is rather for specifying multiple rules for one attribute...
Would appreciate any help!

use provider states to assert each state, if you had an or, your provider may only ever provide you one of the values and pass the verification successfully, never returning the or'd value in real life
