Examples

import {Events, AlertController} from 'ionic-angular';
import {EventsMock, AlertControllerMock} from 'ionic-mocks';

describe('IonicComponent', () => {

    let events: Events;
    let alertCtrl: AlertController;

    let classUnderTest: MyClassUnderTest;

    beforeEach(() => {

        events = EventsMock.instance();
        alertCtrl = AlertControllerMock.instance();

        classUnderTest = new MyClassUnderTest(events, alertCtrl);
    });


    it('should subscribe to events', () => {
    	expect(events.subscribe).toHaveBeenCalled();
    });

    it('should call alert create', () => {

        classUnderTest.showAlert();

        expect(alertCtrl.create).toHaveBeenCalled();
    });
});

Simple Mocking of dependency return types

import {Events, AlertController, Alert} from 'ionic-angular';
import {EventsMock, AlertControllerMock, AlertMock} from 'ionic-mocks';

describe('IonicComponent', () => {

    let alert: Alert;
    let events: Events;
    let alertCtrl: AlertController;

    let classUnderTest: MyClassUnderTest;

    beforeEach(() => {

        events = EventsMock.instance();
        alert = AlertMock.instance():
        alertCtrl = AlertControllerMock.instance(alert);

        classUnderTest = new MyClassUnderTest(events, alertCtrl);
    });


    it('should call present on alert', (done) => {

        classUnderTest.showAlert().then(() => {
            expect(alert.present).toHaveBeenCalled();
            done();
        });

    });
});
