Writing comprehensive unit tests can greatly enhance the reliability of your smart contract, reducing the risk of errors and ensuring that it performs as expected.

Below is an example of a simple unit test for a Solana smart contract written in Rust using the Anchor framework:



mod tests {

use anchor_lang::prelude::*;

use anchor_lang::solana_program::pubkey::Pubkey;


fn test_my_smart_contract() {

// Initialize test context

let mut test = TestContext::default();

// Deploy smart contract

let program_id = test.program_id;

// Perform test actions

// …

// Assert the expected result

// …




In the table below, we summarize the benefits of writing unit tests for smart contract reliability:
