You must run bitcoind or bitcoin-qt with --testnet (testnet3) or --testnet4 arg to launch it in testnet.
I'm assuming the next version of Bitcoin will run v4 with the --testnet command(?)
There's no ETA but it couldn't be the next major release since the PR containing the change is still in "
draft" status.
As of now, I can't see it in v30.0 and v31.0's milestones.
You can bookmark this to know when it'll be released:

https://github.com/bitcoin/bitcoin/issues/31975Great links, thank you.
There is no more [test] network section. The user is expected to set testnet4 explicitly, which should make future rotation of testnets easier.
If a [test] or [testnet3] section is present in bitcoin.conf a warning is issued:
Lol! Eh... feels like [test] should be test, but whatever.
