angularjs - Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL -

i know error appears in questions lot despite efforts didn't manage solve problem.

i have service fetches categories parse. done when running test getting error shown in title.

my code following:

parseservice.js

angular.module('starter').service('parseservice', ['$q', function ($q) {    this.getallcategories = function() {      var deferred = $q.defer();      var categories = [];      var query = new parse.query("category");      query.find({        success: function(results) {          console.log('succesfully queried parse.');          (var = 0; < results.length; i++) {           var result = results[i];           categories.push(result.get("name"));         }          deferred.resolve(categories);          console.log(categories);       },        error: function(error) {          console.log('error querying parse.');          console.log(error);          deferred.reject(error);       }      });      return deferred.promise;    };  }]); 

parseservicetest.js

describe('parseservice', function(){    var service;    beforeeach(function(){     module('starter');   });    ('should fetch categories', function(done){      beforeeach(inject(function(parseservice){       service=parseservice;     }));      var promise = service.getallcategories();      promise.then(function(categories){       expect(categories.length).toequal(5);       done();     });    });  }); 

now console output following:

'succesfully queried parse.' ['pets', 'automobile', 'social', 'retail', 'technology']  error: timeout - async callback not invoked within timeout specified jasmine.default_timeout_interval. 

it seems service returns categories done() method never executed reason.

you can ignore fact don't mock call parse. aware not best practice.

for resolving/rejecting $q promises in tests, need start digest cycle.

describe('parseservice', function() {   var service;   var $rootscope;    beforeeach(module('starter'));    beforeeach(inject(function(parseservice, _$rootscope_) {     service = parseservice;     $rootscope = _$rootscope_;   }));    it('should fetch categories', function(done) {     var promise = service.getallcategories();      promise.then(function(categories) {       expect(categories.length).toequal(5);       done();     });     // run digest cycle resolve $q promises     $rootscope.$digest();   }); });
