Stubbed and Pre-mocked Ionic3 Objects
npm install ionic3-mocks
This project is still very early in development and there are several things I'm sorting out. However since this is only meant
to be used in your tests it should be safe to pull into a project.
bash
npm install --save-dev ionic-mocks

`typescript
import {Events, AlertController} from 'ionic-angular';
import {EventsMock, AlertControllerMock} from 'ionic-mocks';describe('MyClass', () => {
let events: Events;
let alertCtrl: AlertController;
let classUnderTest: MyClass;
beforeEach(() => {
events = EventsMock.instance();
alertCtrl = AlertControllerMock.instance();
classUnderTest = new MyClass(events, alertCtrl);
});
it('should subscribe to events', () => {
expect(events.subscribe).toHaveBeenCalled();
});
it('should call alert create', () => {
classUnderTest.showAlert();
expect(alertCtrl.create).toHaveBeenCalled();
});
