Description
I'm writing an app with NativeScript 6+ and Angular 8+.
I'm trying to write some unit tests and get them up and running.
I have read the documentation on unit testing: https://docs.nativescript.org/tooling/testing/testing
I followed the directions there for setting up the tests and using TestBed. My tests are not working and throwing errors.
Here is my repository: https://github.com/aubrey-fowler/NativeScriptUnitTests
Questions:
- The documentation only shows an example of how to write a test for a component. How do I write a test for a service? I also need to use TestBed for this because my service has dependency injection.
- My tests are throwing errors. Why and how can I fix them?
Errors:
no reachable hosts

code snippet:
import { ItemsComponent } from '../app/item/items.component';
import {
nsTestBedAfterEach,
nsTestBedBeforeEach,
nsTestBedRender
} from 'nativescript-angular/testing';
describe('ItemsComponent Test', () => {
beforeEach(nsTestBedBeforeEach([ItemsComponent]));
afterEach(nsTestBedAfterEach(false));
it('should be defined', () => {
nsTestBedRender(ItemsComponent).then((fixture) => {
fixture.detectChanges();
const component = fixture.componentInstance;
expect(component).toBeTruthy;
});
});
});
