Records and plays back responses from remote web services so you can test your code in peace.
When writing unit tests for APIs that consume remote web services, your goal is to test your code, not the network or remote web service. request-promise-native-record records the answers of these web services and plays them back later.
If a recording does not exist or the environment variable HTTP_MODE is set to record, HTTP responses are written to files when running your tests. You may want to check these files into your VCS. If recordings are available, they will be used automatically for further test runs. No network traffic will occur from now on.

lib/my-api.js:
const request = require('request-promise-native')
class Api {
static getFoo() {
return request.get('http://example.com/')
}
}
module.exports = Api
test/my-api.js:
const assert = require('assert')
const record = require('@heise/request-promise-native-record')
record.start({folder: '/tmp'})
const Api = require('../lib/my-api')
describe('my description', () => {
it('should test my api', async () => {
let response = await Api.getFoo() // 1. call: network request
let response = await Api.getFoo() // 2. call: read from fs
assert.ok(response.includes('Example Domain'))

To save the full response instead of just the response body, use the option resolveWithFullResponse. The Authorization header is removed from the headers object before writing to the hard disk.

const request = require('request-promise-native')
class Api {
static getFoo() {
return request.get('http://example.com/', {resolveWithFullResponse: true})
}
}
module.exports = Api
request-promise-native is supported as HTTP lib.request.get() is supported.v1.0.13, 2019-06-11
