I am currently in the process of creating a unit test for this Angular 2+ service (see code snippet below). Can anyone provide guidance on how to accomplish this using the Jasmine framework?
declare var window: any;
@Injectable
export class Somename {
constructor() {
if (window.cordova) {
function1();
} else {
function2();
}
}
private function1() {
}
private function2() {
}
}
Here is a basic structure you can use as a starting point:
describe('ComponentExample', () => {
let component: ComponentExample;
let fixture: ComponentFixture<ComponentExample>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [ ComponentExample ]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(ComponentExample);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should create', () => {
// Initialize cordova here
expect(component).toBeTruthy();
// Do not launch cordova here
expect(component).toBeTruthy();
});
});
This code snippet is designed to test the constructor of a component, focusing on checking if it initializes properly before and after launching cordova. It's important to verify the component state regardless of cordova being operational or not.
When it comes to testing ngOnInit versus the constructor, the key difference lies in their functionality. While the constructor sets up the initial state of a component, ngOnInit is primarily used for executing code when routing within an application. The ng test --code-coverage command can help you ensure that all lines of your code are covered during testing.
