Testing with mocha, a custom fixture utility, ES6 destructuring, and ES7 async/await

gistfile1.js

describe('as a super administrator', function() {
  it('create a session', async function(done) {
    var {
      user,
      password
    } = await fixtures(['User'], {
      user: { superAdministrator: true }
    })

    request(app)
      .post('/api/sessions')
      .set('Content-Type', 'application/json')
      .send({
        username: user.username,
        password: password
      })
      .expect(200)
      .end(done)
  })
