title_body: Does the testnet faucet still exist? How to create testnet ADA?
upvoted_answer: You can request tAda from the test faucet here. By adding an address without an API key you will receive 1000 tAda. You could also request an API key from IOHK to have a bespoke amount of tAda/Testcoin if required. Once you're finished with your tAda you should return them to this address (which you can see on the official documentation page too).
