About

An updated, modern network recorder with the goal of being test framework agnostic. Inspired by:

Install

npm install --save-dev nock-dvr

Usage

  • [x] Works with Mocha
  • [ ] Works with Jest

When you need to record cassettes you can either:

  • Use dvr.describe instead of describe
  • Use dvr.it instead of it

dvr.describe will record an episode before each test in that block. So you can have multiple its and it will record any requests within them.

dvr.it will record a cassette for one specific test.

They both support .skip and .only as mocha does.

const request = require('request');
const assert = require('assert');
const dvr = require('nock-dvr');

describe('normal test', function() {
  dvr.it.only('works', function(done) {
    request('http://localhost:4000/users', function(err, res, body) {
      assert(!err, 'was success');
      done();
    });
  });

  it('some other test', function() {
    // You can use mocha how you normally would to group tests
  });
});

dvr.describe.skip('skipped test', function() {
  // Anything in here will be skipped
  // If the skip is removed, this request would be recorded for playback in
  // later tests
  it('makes request', function(done) {
    request('http://localhost:4000/users', function(err, res, body) {
      assert(!err, 'was success');
      done();
    });
  });
});

Configuration

List of available configuration options

Test specific configuration

dvr.it('works', {
  mode: 'all'
}, function(done) {
  request('http://localhost:4000/users', function(err, res, body) {
    assert(!err, 'was success');
    done();
  });
});

dvr.describe('works', { mode: 'all' }, function() {
  it('makes request', function(done) {
    request('http://localhost:4000/users', function(err, res, body) {
      assert(!err, 'was success');
      done();
    });
  });
});

Global Configuration

A dvr.config method is exposed to set default configuration on a global level. This should be done before any of your tests have run. In mocha you can put this in a helper file.

const dvr = require('nock-dvr');

dvr.config({
  excludeScope: ['github.com']
});
