iOS, Android

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

• CLI: (run tns --version to fetch it)

  node_modules/tns-core-modules/package.json file in your project)
  3.3.0

• Runtime(s): (look for the "tns-android" and "tns-ios" properties in the
  package.json file of your project)
  3.0.0

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

• Build a service that requires injection of TranslateService (from ng-translate)
• Inject that service in beforeEach() of a test suite.

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

error.service.test.ts

'use strict';

import {ErrorService} from '../services/error.service';
import {inject} from "@angular/core/testing";

declare let assert: Chai.AssertStatic;

describe("ErrorService tests", () => {

    let service = null;

    beforeEach((done) => {
        inject([ErrorService], (injectService: ErrorService) => {
            service = injectService;
            done();
        });
    });

    it("Service exists", (done) => {
        assert.exists(service);
        done();
    });

});

error.service.ts

import { Injectable } from "@angular/core";
import { TranslateService } from "ng2-translate";

@Injectable()
export class ErrorService {

    constructor(private i18n: TranslateService) {
    }
}

Comienza reproduciendo el fallo de prueba de tns informado con las versiones indicadas para CLI, módulos y runtimes. Lee error.service.test.ts y error.service.ts, centrándote en la inyección de testing de Angular en beforeEach(). Se considera terminado cuando la prueba del servicio se ejecuta tanto en iOS como en Android sin el ReferenceError relacionado con Zone.
