jasmine 2.0 testing angularjs factory method which returns a promise

Question

when i am trying to test a function which returns a promise i get the following error:

"Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.

"

my spec is as follows:

describe('async promise test', function () {

    beforeEach(module('app'));

    beforeEach(function () {
         jasmine.DEFAULT_TIMEOUT_INTERVAL = 6 * 1000;
    })

    it('should match the name', function (done) {
        inject(function ($rootScope,promiseTest) {
          $rootScope.$apply(function(){
             var promise =promiseTest.checkPromise();
            promise.then(function(data){
           console.log(data);
           done();
          })
        })
      })
    })
});

Answer 1

You are using the mock module, which overrides $timeout, so that tests are repeatable (ref)!

You have to use $timeout.flush(1000); (and the $apply() is redundant):

it('should match the name', function (done) {
  inject(function (promiseTest,$timeout) {
    var promise =promiseTest.checkPromise();
    promise.then(function(data){
      console.log(data);
      done();
    });
    $timeout.flush(1000);
  });
});

You have to inject the $timeout into your test, and flush it:

 inject(function ($rootScope,promiseTest, $timeout) {
      $rootScope.$apply(function(){
         var promise =promiseTest.checkPromise();
         console.log("Created promise")
        promise.then(function(data){
       console.log(data);
       done();
      })
    });
    $timeout.flush();
