Can someone explain how I can effectively test the internal workings of a promise using Jasmine?

Within the Angular component I am testing, there is an async promise that I am struggling to examine. The code inside the 'then' block is crucial for my testing purposes, but I cannot seem to access it.

angular.module('Ls', [
])

function Locale($rootScope, $http) {

  var API = {
    getAvailables: getAvailables

  };
  API.getAvailables().then(function(data) {
        ..........perform certain actions
     ........I am particularly interested in testing this specific code segment!!!

      });

 function getAvailables() {
      return $http.get('/l.json').then(function(response) {
        return response.data;
    });
 }

Answer №1

If you want to make sure that getAvailables always resolves, you have two options. You can either use sinon to stub it or extract the callback to a separate function for testing purposes.

Choice 1

sinon.stub(API, 'getAvailables').resolves(data);

Choice 2

API.getAvailables().then(handleResponse);

^ Verify the functionality of the handleResponse function
