NativeScript - how to get unit tests to work properly?
See original GitHub issueI’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
on my Android phone
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;
});
});
});

Thank you for the repo @aubrey-fowler - we’ll take a look!
@NathanWalker doesnt work either:
To reproduce:
Sadly my project runs into the exact same issues about setting up the UnitTests, thats why its impossible to use them at the moment, which is pretty bad because some stuff needs to be covered with it…
