nock-utils

Utility tools to simplify recording and playing back http requests during tests

Quick Example

const nockUtils = require('nock-utils');
const recorder = new nockUtils.HttpRecorder('cassette.json');
recorder.start();
 
// Call http requests here.
 
recorder.stop();

Complete Example

// Import nock-utils
const nockUtils = require('nock-utils');
const rest = require('rest');
 
// Instantiate HttpRecorder passing the cassette location.
const recorder = new nockUtils.HttpRecorder('cassette.json');
const startTime = new Date();
 
// If cassette.json DOES NOT exist it will start recording all http transactions.
// If cassette.json DOES exist it will playback http requests contained in the cassette.
recorder.start();
 
rest('https://www.comparaonline.com').then((result) => {
 
  // This will stop recording and save a new cassette or reset nock.
  recorder.stop();
 
  const elapsedMilliseconds = new Date() - startTime;
  console.log(elapsedMilliseconds);
});

Testing all mocks ran

You can validate all mocks were executed by passing a true to the nock.stop method:

async () => {
  recorder.start();
  await rest('https://www.comparaonline.com');
  recorder.stop(true); // This will throw if the cassette had more mocks than just that request.
}
