Solana Mint Fixture

Solana Mint Fixture is a lightweight utility library for creating and initializing SPL Token 2022 mints and ATAs in both Solana BanksClient based tests and real RpcClient environments.

Features

• Create and initialize a new Mint account
• Derive and create an Associated Token Account (ATA)
• Mint tokens to the ATA
• Works with:
  • BanksClient (for Solana program tests)
  • RpcClient (for integration/e2e testing)

Usage

Add to your Cargo.toml:

# Enables only `banks` feature
solana-mint-fixture = { version = "0.1.0", default-features = false, features = ["banks"] }

# Enables only `rpc` feature
solana-mint-fixture = { version = "0.1.0", default-features = false, features = ["rpc"] }

# Enables `full` features (by default)
solana-mint-fixture = "0.1.0"

Example

let fixture: MintFixture = MintFixture::new(
    MintFixtureClient::Banks(&banks_client),
    &payer_keypair,
    &payer_pubkey,
    &rent,
);

// make sure that the blockhash does not expire!
let decimals: u8 = 9;
let mint: Pubkey = fixture.create_and_initialize_mint_without_freeze(decimals, &blockhash).await?;
let ata: Pubkey = fixture.create_and_initialize_ata(&mint, &blockhash).await?;
fixture.mint_to_ata(&mint, &ata, 1_000_000_000 * 10u64.pow(decimals as u32), &blockhash).await?;
