For intergration tests, always remember when you create a 'mass' you should aslo clean up the 'mass'.

For example when you start the server, you need to close the server after the tests. See the post: http://www.cnblogs.com/Answer1215/p/7554662.html

Also for authentication, when you create a new user for testing, you should also clean it up.

There is a help function for tests, to create a new user:

async function createNewUser(overrides) {
  const password = faker.internet.password()
  const userData = generateUserData(overrides)
  const {email, username} = userData
  const user = await api
    .post('users', {user: {email, password, username}})
    .then(getUser)
  return {
    user,
    cleanup() {
      return api.delete(`users/${user.username}`)
    },
  }
}

In the return value, it also provide a function to clean up the user.

const api = axios.create({
  baseURL: 'http://localhost:3000/api',
})

describe('authenticated', () => {
  let cleanupUser
  beforeAll(async () => {
    const results = await createNewUser()
    cleanupUser = results.cleanup
    api.defaults.headers.common.authorization = `Token ${results.user.token}` // set default http header, add authorization for JWT token
  })

  afterAll(async () => {
    await cleanupUser()
    api.defaults.headers.common.authorization = ''
  })

})
