litesvm-utils

General testing utilities for LiteSVM that simplify Solana program testing.

This crate provides framework-agnostic helpers for:

• Account creation and funding
• Token operations (mints, accounts, minting)
• Transaction execution and result analysis
• Assertion helpers for testing
• PDA derivation

Features

• Test Account Helpers: Create funded accounts, mints, and token accounts in single calls
• Transaction Helpers: One-line transaction execution with automatic error handling
• Assertion Helpers: Clean, readable test assertions for account states
• Builder Pattern: Fluent API for setting up test environments
• Framework Agnostic: Works with any Solana program, not just Anchor

Quick Start

use litesvm_utils::{LiteSVMBuilder, TestHelpers, AssertionHelpers, TransactionHelpers};
use solana_program::pubkey::Pubkey;

// Initialize with one line!
let program_id = Pubkey::new_unique();
let program_bytes = include_bytes!("../target/deploy/program.so");
let mut svm = LiteSVMBuilder::build_with_program(program_id, program_bytes);

// Create test accounts in one line each
let maker = svm.create_funded_account(10_000_000_000).unwrap();
let mint = svm.create_token_mint(&maker, 9).unwrap();

// Send instructions and analyze results
let result = svm.send_instruction(ix, &[&maker]).unwrap();
result.assert_success();

// Clean assertions
svm.assert_token_balance(&token_account, 100);
svm.assert_sol_balance(&maker.pubkey(), 10_000_000_000);
