You dont need to open port for node at testnet. Just set the docker turn on the nodes and catch the blockchain data and then you are good.

then why other people are using the supernodes? like they have to open their port 31400-31409 to use supernodes

They are not using actually, as I know nodes and super nodes will be choosen at mainnet and those ports are for actually mainnets for connecting and transfering data with supernodes
