Chai oczekuj rzutów asynchronicznych

const chai = require('chai')
const expect = chai.expect
chai.use(require('chai-as-promised'))

// Always succeeds
async function wins() {
  return 'Winner'
}

// Always fails with an error
async function fails() {
  throw new Error('Contrived Error')
}

it('wins() returns Winner', async () => {
  expect(await wins()).to.equal('Winner')
})

it('fails() throws Error', async () => {
  await expect(fails()).to.be.rejectedWith(Error)
})
