Truffle Test array 예제

간단하게 array를 세팅하는 solidity코드 및 테스트코드 예제입니다. (제가 작성한 건 아니지만..^^)

사전환경: $ganache-cli   ( -l 1000000000 -p 7545)  

               /migrations밑에 2_deploy_contracts.js에 TestArray.sol 추가. 

실행방법: $truffle compile -> $truffle migrate -> $truffle test  

  혹은

          $truffle develop

          $migrate

          $test (test/testarray.test.js)

      $truffle network 하면 deploy된 address를 볼 수 있음.

Solidity 소스:

pragma solidity ^0.4.24;

contract TestArray {

    uint[] heroArray;

    constructor() public {

    }

    function setHeroArray(uint[] array) public {
        for (uint i=0 ; i < array.length; i++) {
            setValue(array[i]);
        }
    }

    function setValue(uint a) private {
        heroArray.push(a);
    }

    function getHeroArray(uint a) view public returns(uint[]) {
        return heroArray;
    }

}

test/testarray.test.js 소스:

const assert = require('assert');
const ganache = require('ganache-cli');
const Web3 = require('web3');
const web3 = new Web3(ganache.provider());
const json = require('./../build/contracts/TestArray.json');

let accounts;
let arraySC;
const interface = json['abi'];
const bytecode = json['bytecode'];

beforeEach(async() => {
    accounts = await web3.eth.getAccounts();
    arraySC = await new web3.eth.Contract(interface)
        .deploy({data: bytecode})
        .send({from: accounts[0], gasLimit: 4000000});
});

describe(' --- Test Array --- ', () => {
   it('array Set', async() => {
        await arraySC.methods.setHeroArray([3,3,4]).send({from: accounts[0], gasLimit:150000});

        let resultArray = await arraySC.methods.getHeroArray(1).call();

        console.log('resultArray : ', resultArray);
        assert.equal(resultArray[2], 4, "값이 제대로 세팅되지 않았습니다 ");
   });
});
