Convenience data structures and methods for interacting with the Solana program test context.

Examples

Assume there's a Solana program with a processor of the form

// foo_program::processor
fn processor(
    id: &Pubkey,
    accounts: &[AccountInfo],
    data: &[u8]
) -> Result<(), ProgramError>
{
    // snip
    Ok(())
}

It can be loaded into the testbench as

use agsol_testbench::{Testbench, TestbenchProgram, TestUser};
use solana_program_test::processor;

// program `foo` with program pubkey FOO_PROGRAM_ID
let program_from_processor = TestbenchProgram {
    name: "foo_bpf_program",
    id: FOO_PROGRAM_ID,
    process_instruction: processor!(foo_program::processor),
};

// program `bar` with program pubkey BAR_PROGRAM_ID
let program_from_binary = TestbenchProgram {
    name: "bar_bpf_program",
    id: BAR_PROGRAM_ID,
    process_instruction: None,
};

// load programs into the test context
let mut testbench = Testbench::new(&[program_from_processor, program_from_binary]).await.unwrap();

// create a test user with an airdrop
let test_user = TestUser::new(&mut testbench).await.unwrap().unwrap();
