Non-ITN TestNet for Staking Pool?

Hi,

I am following Stake Pool courses and prepare to setup a staking pool to test on test net before put it to main net. I noticed that many Testnet staking discussion / resources are for ITN using Jormungandr.

Is the Test net still available for testing Cardano-node staking pool? Is the test net faucet still works for that purpose these days? (as of July 2021?).

Please help.

Thank you in advance

Jason
