Just try to configure a test module

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

import { TestBed } from "@angular/core/testing";
import { NativeScriptModule } from "nativescript-angular/platform";
import { NativeScriptFormsModule } from "nativescript-angular/forms"
import { NativeScriptHttpModule } from "nativescript-angular/http";
import { UserService } from "../../../shared/services";
import { IdentifiedHttp } from "../../../shared/util";

describe("UserService tests", () => {
    beforeEach(() => {
        TestBed.configureTestingModule({
            imports: [
                NativeScriptModule,
                NativeScriptFormsModule,
                NativeScriptHttpModule,
            ],
            declarations: [ UserService ],
            providers: [ IdentifiedHttp ]
        });
    });
});

@NathanWalker I saw you were showing examples on tests during the developer day workshop (https://nativescript.github.io/developer-day-workshop/#chapter6.8) and actually being able to configure a TestBed, some clue you can give me on why it is not finding the Zone ?.

Thanks in advance!

try this:

import 'nativescript-angular/zone.js/dist/zone-nativescript';
import {BrowserDynamicTestingModule,platformBrowserDynamicTesting} from '@angular/platform-browser-dynamic/testing';
import {NS_COMPILER_PROVIDERS} from 'nativescript-angular/platform';
import {TestBed} from '@angular/core/testing';

TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting(NS_COMPILER_PROVIDERS));

worked for me

I get

TestBed isn't supported officially supported yet. It seems great some people are able to get it working, but we haven't put any dedicated effort into it so far.

[nakedcity]

is it planned to support it?

[hdeshev]

No, it isn't planned for any of the upcoming releases. We'd consider a PR if someone is willing to investigate this.

[nakedcity]

What way is then for now adviced to test NG2 apps?

[hypery2k]

you can take a look at my angular sample here: https://github.com/TobiasHennig/nativescript-toast/blob/master/samples/angular/app/tests/app.component.spec.ts

I've using TestBed: https://github.com/TobiasHennig/nativescript-toast/blob/master/samples/angular/app/tests/setup.js

you can check it for yourself, just clone the repo:

cd samples/angular
npm run clean && npm run build
npm run test // only on macOS

@hypery2k Does this still run for you?
I get:
Error: Not implemented! at NativeScriptDomAdapter.setGlobalVar

Using NativeScript 3, with Karma (and the rest of the setup like yours).
