How does one stub promise with sinon?

Question

I have a data service with following function

function getInsureds(searchCriteria) {

    var deferred = $q.defer();

    insuredsSearch.get(searchCriteria,
         


        

Answer 1

Also you can do something like this:

import sinon from 'sinon';

const sandbox = sinon.sandbox.create();

const promiseResolved = () => sandbox.stub().returns(Promise.resolve('resolved'));
const promiseRejected = () => sandbox.stub().returns(Promise.reject('rejected'));

const x = (promise) => {
  return promise()
    .then((result) => console.log('result', result))
    .catch((error) => console.log('error', error))
}

x(promiseResolved); // resolved
x(promiseRejected); // rejected
