QUnit is very easy to get started with, as you only need to include two files and a little bit of markup, then you can start writing tests. Jasmine strength, afaik is its BDD-style syntax, if that is something that you prefer (probably not a selling point for you) and tight integration into Ruby/Rails tools. … Read more
You can inject mocks into your service by using $provide. If you have the following service with a dependency that has a method called getSomething: angular.module(‘myModule’, []) .factory(‘myService’, function (myDependency) { return { useDependency: function () { return myDependency.getSomething(); } }; }); You can inject a mock version of myDependency as follows: describe(‘Service: myService’, function … Read more
I guess there are two types of tests you can do: Unit tests that fake the AJAX request (using Jasmine’s spies), enabling you to test all of your code that runs just before the AJAX request, and just afterwards. You can even use Jasmine to fake a response from the server. These tests would be … Read more

The ngMock module is automatically loaded for every Angular test, and it initializes the mock $httpBackend to handle any use of the $http service, which includes template fetching. The template system tries to load the template through $http and it becomes an “unexpected request” to the mock. What … Read more
Use the not operator: expect(controller.bar).not.toHaveBeenCalled();
I was able mock multiple calls and check the arguments this way: expect(mockFn.mock.calls).toEqual([ [arg1, arg2, …], // First call [arg1, arg2, …] // Second call ]); where mockFn is your mocked function name.
You can use spy.and.returnValues (as Jasmine 2.4). for example describe(“A spy, when configured to fake a series of return values”, function() { beforeEach(function() { spyOn(util, “foo”).and.returnValues(true, false); }); it(“when called multiple times returns the requested values in order”, function() { expect(util.foo()).toBeTruthy(); expect(util.foo()).toBeFalsy(); expect(util.foo()).toBeUndefined(); }); }); There is some thing you must be careful about, there … Read more

In February 2017, they merged a PR adding this feature, they released in April 2017. so to spy on getters/setters you use: const spy = spyOnProperty(myObj, ‘myGetterName’, ‘get’); where myObj is your instance, ‘myGetterName’ is the name of that one defined in your class as get myGetterName() {} and the third param is the type … Read more
