how can he be sure of the random index???

Hi, in the unit testes of raffle, i see that he assumes that account 2 will be the winner. I cant understand why is that., because he is calling performUpKeep that requests the random number first.

Hi @h0leee

Actually there's no assumption -- the VRFCoordinatorV2Mock it's just a contract to replicate/mock a few functions from the real contract. In our local blockchain there's no randomness the first account to enter the raffle will be the winner.

so on the local network wont be an off chain computation??? makes sense, thanks

Testing in local network means no off-chain computation and no randomness.
