Angular 2 Testing with Javascript Library as a dependency -


i'm trying write test component, uses javascript library. therefore declared object on top, make available in typescript. far :-) no i'm trying run test, fails because test doesn't know declared object in component.

how make object available inside test spec?

import { component } '@angular/core'; declare var h: any;  @component({   selector: 'fb-root',   templateurl: './app.component.html',   styleurls: ['./app.component.scss'] })  export class appcomponent {   title = 'request vehicle';   test = this.title == this.title;    ngoninit(): void {     var mapcontainer = document.createelement('div');     var uiview = document.getelementbyid('map-container');      mapcontainer.setattribute('id', 'map');     mapcontainer.setattribute('style', 'width: 100%; height: 100vh; background: grey');     uiview.appendchild(mapcontainer);      let platform = new h.service.platform({       app_id: '',       app_code: '',       usecit: true,       usehttps: true   });     // obtain default map types platform object:   var defaultlayers = platform.createdefaultlayers();    // instantiate (and display) map object:   var map = new h.map(     document.getelementbyid('map'),     defaultlayers.normal.map,     {       zoom: 10,       center: { lat: 53, lng: 18 }     });   } }    import { testbed, async } '@angular/core/testing'; import { routertestingmodule } '@angular/router/testing';  import { appcomponent } './app.component';  describe('appcomponent', () => {  beforeeach(async(() => {    testbed.configuretestingmodule({     imports: [       routertestingmodule     ],     declarations: [       appcomponent     ],   }).compilecomponents();  }));  it('should create app', async(() => {   const fixture = testbed.createcomponent(appcomponent);   const app = fixture.debugelement.componentinstance;   expect(app).tobetruthy(); }));  it(`should have title 'request vehicle'`, async(() => {   const fixture = testbed.createcomponent(appcomponent);   const app = fixture.debugelement.componentinstance;   expect(app.title).toequal('request vehicle'); }));  it('should render title in h1 tag', async(() => {   const fixture = testbed.createcomponent(appcomponent);   fixture.detectchanges();   const compiled = fixture.debugelement.nativeelement;   expect(compiled.queryselector('h1').textcontent).tocontain('request vehicle');  })); });
