Problem

close #2680

Summary of Changes

• Add an option rust-template in anchor init -t command.
• Add rust test templates.

I am submitting this pull request for review. As I am not entirely confident about my implementation, I would greatly appreciate any advice or suggestions. I am open to feedback and happy to make any necessary adjustments.

@aoikurokawa is attempting to deploy a commit to the coral-xyz Team on Vercel.

A member of the Team first needs to authorize it.

Thank you for starting on this!

Can we add this as a template instead of a separate flag? It would also be much easier to add it that way since you can just specify all the necessary files in one place similar to

anchor/cli/src/rust_template.rs

Line 69 in 94fde24

fn create_program_template_multiple(name: &str, program_path: &Path) -> Files {

[aoikurokawa]

Thank you for the review.
Following your advice, I've added a new option to the --template rust-test.
I welcome any further advice or suggestions you might have.

[acheroncrypto]

Awesome work, thanks! A few more things and it should be good to merge.

@acheroncrypto
Thank you for reviewing. I relocated the code associated with testing to pub fn create_test_files function.

[acheroncrypto]

Thank you!

For anyone wishing to try this, use

anchor init --test-template rust aaa

Look inside tests/src/test_initialize.rs

You'll see a file with the contents:

use std::str::FromStr;

use anchor_client::{
    solana_sdk::{
        commitment_config::CommitmentConfig, pubkey::Pubkey, signature::read_keypair_file,
    },
    Client, Cluster,
};

#[test]
fn test_initialize() {
    let program_id = "ALBsctEzCR2MuZ65KczywWQYEyhjdbq7B5LnkuYg1sie";
    let anchor_wallet = std::env::var("ANCHOR_WALLET").unwrap();
    let payer = read_keypair_file(&anchor_wallet).unwrap();

    let client = Client::new_with_options(Cluster::Localnet, &payer, CommitmentConfig::confirmed());
    let program_id = Pubkey::from_str(program_id).unwrap();
    let program = client.program(program_id).unwrap();

    let tx = program
        .request()
        .accounts(aaa::accounts::Initialize {})
        .args(aaa::instruction::Initialize {})
        .send()
        .expect("");

    println!("Your transaction signature {}", tx);
}

Then run anchor test

Hi, this feature is so good, we want use only rust when developing smart contracts. But this feature isn't well documented. For this reason I want to ask my question in here.

#[derive(Accounts)]
pub struct Initialize<'info> {
    #[account(
        init,
        payer = signer,
        space = Counter::SPACE
    )]
    pub counter: Account<'info, Counter>,

    #[account(mut)]
    pub signer: Signer<'info>,

    pub system_program: Program<'info, System>,
}

// ....
// test code:

    let tx = program
        .request()
        .accounts(anchor_tutor_1::accounts::Initialize {
            counter: payer.pubkey(),
            signer: payer.pubkey(),
            system_program: system_program::ID,
        })
        .args(anchor_tutor_1::instruction::Initialize {})
        .send()
        .expect("Transaction failed");

This code isn't working. The error message:

thread 'test_initialize::test_initialize' panicked at tests/src/test_initialize.rs:31:10:
Transaction failed: SolanaClientError(Error { request: Some(SendTransaction), kind: RpcError(RpcResponseError { code: -32002, message: "Transaction simulation failed: Error processing Instruction 0: custom program error: 0x1005", data: SendTransactionPreflightFailure(RpcSimulateTransactionResult { err: Some(InstructionError(0, Custom(4101))), logs: Some(["Program 3CobDehW5cufiguMpJD75msFSngrerxat9znyCFUX3gR invoke [1]", "Program log: Instruction: Initialize", "Program log: AnchorError thrown in programs/anchor-tutor-1/src/instructions/initialize.rs:7.

So how can I sovle this? Thanks.

[aoikurokawa]

I think the account of counter should not be payer.

let counter = Keypair::new();

    let tx = program
        .request()
        .accounts(anchor_tutor_1::accounts::Initialize {
            counter: counter.pubkey(),
            signer: payer.pubkey(),
            system_program: system_program::ID,
        })
        .args(anchor_tutor_1::instruction::Initialize {})
        .send()
        .expect("Transaction failed");

@aoikurokawa thanks for your response. I searched in google but I didn't find information about writing tests inside of rust. Do you have any suggestion about documentation, example code etc? Thanks.

I think you can refer solana program library code.
https://github.com/solana-labs/solana-program-library/blob/master/stake-pool/program/tests/initialize.rs

Most test codes are written in Rust. So I think you can take some hints from it.
