Code by @gr2m -- 5 min example he showed me of how @node-nock can mock an API for testing

nock-example.js

const assert = require('assert')

const nock = require('nock')
const axios = require('axios')

// nock('https://api.github.com')
//   .get('/')
//   .reply(200, {
//     current_user_url: 'https://api.github.com/user'
//   })

nock.recorder.rec()

myLib()

.then(result => {
  assert.equal(result.current_user_url, 'https://api.github.com/user')
  console.log('ok')
}, assert.ifError)

function myLib () {
  return axios.get('https://api.github.com')

  .then(result => result.data)
}
