Tell us about the problem

I can not configure a testing module, on the start of the tests it throws:

NativeScript / 9.1 (9.1; iPhone)  ../../tests/shared/services/user.service.spec.js at line 0 FAILED
    ReferenceError: Can't find variable: Zone
NativeScript / 9.1 (9.1; iPhone): Executed 1 of 0 (1 FAILED) ERROR (0.033 secs / 0 secs)

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

CLI: 2.3.0
Cross-platform modules:

Runtime(s): ios 2.3.0

Please tell us how to recreate the issue in as much detail as possible.

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

@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!

related to #478

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

TypeError: undefined is not an object (evaluating 'ProxyZoneSpec.assertPresent') (line 178439)
	resetFakeAsyncZone
	attemptSync

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.

is it planned to support it?

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

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

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

@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).

@hypery2k

@hauthorn I just tried @hypery2k's config and I got the same error:

NativeScript / 10.3.1 (10.3.1; iPhone) LoginPage should init FAILED
	Error: Not implemented! in file:///app/tns_modules/nativescript-angular/zone-js/dist/zone-nativescript.js (line 993)
	setGlobalVar@file:///app/tns_modules/nativescript-angular/dom-adapter.js:148:95 [ProxyZone]
	_createNgProbe@file:///app/tns_modules/@angular/platform-browser/./bundles/platform-browser.umd.js:2383:26 [ProxyZone]
	createInternal [ProxyZone]

BTW, does your console also have all the @file and in file lines? How do I disable them, they're just noise to me.

@hauthorn Check this out: #733. I was able to fix that setGlobalVar method by just writing over it. Not sure if this is the right thing to do...but TestBed works for me now.

Is TestBed supported in NativeScript? It seems like there are a bunch of potential workarounds that everyone tries, but without success. It is very important for my team to be able to use TestBed to initialize components which have numerous dependencies.

@Ahnert1

@Ahnert1 here you can find an example on how to configure testBed in NativeScript

Hey,

I have been working on trying to get TestBed configured properly in NativeScript for a month now and still haven't gotten it. The example provided is not sufficient as I have attempted to reproduce it and still face issues. I am unsure of what I am doing wrong.

Please checkout my Stack Overflow question if you have been able to get TestBed working in NativeScript I would very much appreciate it.
