how do I use Token2022 with local Anchor tests?

Question

I've downloaded and built the token 2022 program, and added to the Anchor.toml like this:

[[test.genesis]]
address = "TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb"
program = "spl_token_2022.so"

However, I'm now getting strange errors:

Instruction references an unknown account [xyz pubkey]...
An account required by the instruction is missing

and the account listed a) doesn't match up with anything I'm passing, and b) seems to change on each run.

Any thoughts? Thanks

The issue ended up being init for an associated token account. As of 0.27.0 init uses the regular Token program, so it was trying to create a regular Token ATA when it needed a Token2022 ATA. There is a token_program constraint coming in 0.28.0. As a workaround for now, this can be done by created the ATA as a preInstruction (not relying on init) using createAssociatedTokenAccountIdempotent. Then, all you need are constraints on the ATA being passed in, like:

    #[account(
        constraint = ata.owner == some_owner.key(),
        constraint = ata.mint == some_mint.key()
    )]
