Girino is a chai module to improve truffle test development.

Installation

yarn add girino -D
# or
npm install girino --save-dev

Usage

const SimpleToken = artifacts.require('SimpleToken');
const BigNumber = require('bignumber.js');
const chai = require('chai');
const girino = require('girino');

const { expect } = chai;

chai.use(girino);

contract('SimpleToken', (accounts) => {
    let simpleToken;
    const aToken = new BigNumber('1');
    const mainAccount = accounts[0];
    const userAccount = accounts[1];
    const receiverAccount = accounts[2];

    before(async () => {
        simpleToken = await SimpleToken.deployed();
    });

    it('should revert', () => expect(
        simpleToken.transfer(receiverAccount, aToken, { from: userAccount }),
    ).to.revert);

    it('should revertWith', () => expect(
        simpleToken.transfer(receiverAccount, aToken, { from: userAccount }),
    ).to.revertWith('SafeMath: subtraction overflow'));

    it('to emit', () => expect(
        simpleToken.transfer(receiverAccount, aToken, { from: mainAccount }),
    ).to.emit('Transfer'));

    it('withArgs success', () => expect(
        simpleToken.transfer(receiverAccount, aToken, { from: mainAccount }),
    ).to.emit('Transfer').withArgs(mainAccount, receiverAccount, aToken));
});

And then just run tests as you are used to, with truffle test
