nock and cucumber

Hey there, how are you?

The real coder doesn't test. Only the ones who fear are testing. But not him.

(from here)

nock is an HTTP mocking and expectations library for Node.js

Examples

var nock = require('nock');
 
var couchdb = nock('https://kikoo.js')
  .get('/users/1')
  .reply(200, {
    _id: '123ABC',
    _rev: '946B7D1C',
    username: 'toto',
    email: 'toto2015@kikoo.js'
  });
var scope = nock('https://kikoo.js')
  .post('/users', {
    username: 'toto',
    email: 'toto2015@kikoo.js'
  })
  .reply(201, {
    ok: true,
    id: '123ABC',
    rev: '946B7D1C'
  });
