Я установил библиотеку jasmine-jquery-matchers, используя npm, в свое приложение Angular 6.Запуск тестов вызывает следующую ошибку:
ERROR in [at-loader]
./src/app/landing/components/title/title.component.spec.ts:51:30
TS2339: Property 'toBeVisible' does not exist on type 'Matchers<any>'.
Вот моя спецификация теста:
import { ComponentFixture, TestBed } from '@angular/core/testing';
import { TitleComponent } from './title.component';
import { FormsModule } from '@angular/forms';
import { RouterTestingModule } from '@angular/router/testing';
import { UserInfoService } from '../../../shared/services/user-info.service';
import {DebugElement} from "@angular/core";
import {By} from "@angular/platform-browser";
import { matchers } from "jasmine-jquery-matchers/dist/jasmine-jquery-matchers" ;
describe('Title Component', () => {
let component: TitleComponent;
let fixture: ComponentFixture<TitleComponent>;
let userInfoService: UserInfoService;
let el: DebugElement;
//const matchers = window['jasmine-jquery-matchers'];
beforeEach(() => {
jasmine.addMatchers(matchers);
TestBed.configureTestingModule({
imports: [ FormsModule, RouterTestingModule ],
declarations: [ TitleComponent ],
providers: [ UserInfoService ]
});
fixture = TestBed.createComponent(TitleComponent);
component = fixture.componentInstance;
userInfoService = TestBed.get(UserInfoService);
});
it("should be visible when the user service's isPageTitleEnabled() method returns true", () => {
el = fixture.debugElement.query(By.css('div.tc-title'));
spyOn(<any>UserInfoService.prototype, 'isPageTitleEnabled').and.returnValue(true);
fixture.detectChanges();
expect(el.nativeElement.children.length).toEqual(1);
el = el.query(By.css('span.tc-header-title'));
expect(el.nativeElement).toBeVisible();
});
});
Существуют другие тесты, которые я не включил, потому что они все работают.
Вот трассировка стека:
TypeError: expect(...).toBeVisible is not a function

Может быть, мне нужно что-то настроить в karma.conf.js?Я добавил его в качестве основы:
frameworks: ['jasmine', "jasmine-jquery-matchers"],
Любая помощь будет высоко ценится!
