@name Developer Guide: Angular Services: Testing Angular Services
@description
Following is a unit test for the service in the example in {@link
dev_guide.services.creating_services Creating Angular Services}. The unit test example uses Jasmine
spy (mock) instead of a real browser alert.
<pre>
var mock, notify;
beforeEach(function() {
mock = {alert: jasmine.createSpy()};
notify = angular.module.ng('notify')(mock);
});
it('should not alert first two notifications', function() {
notify('one');
notify('two');
expect(mock.alert).not.toHaveBeenCalled();
});
it('should alert all after third notification', function() {
notify('one');
notify('two');
notify('three');
expect(mock.alert).toHaveBeenCalledWith("one\ntwo\nthree");
});
it('should clear messages after alert', function() {
notify('one');
notify('two');
notify('third');
notify('more');
notify('two');
notify('third');
expect(mock.alert.callCount).toEqual(2);
expect(mock.alert.mostRecentCall.args).toEqual(["more\ntwo\nthird"]);
});
</pre>
