Угловой TestBed - Карма / Жасмин |Неожиданное импортированное значение 'BrowserDynamicTestingModule' |Угловой АОТ

Question

Пример кода тестового стенда, следуя указаниям https://angular.io/guide/testing -

describe("Login", () => {
  let loginService: LoginService;

  beforeEach(() => {
    TestBed.configureTestingModule(
        { providers: [LoginService] }
    );

    loginService = TestBed.get(LoginService); // ERROR
  });

  it("login testing", (done: DoneFn) => {}); // Empty test
}

Boot.ts, потому что это единственный другой файл, который содержит что-либосвязанные с BrowserDynamicTestingModule -

import { enableProdMode }           from "@angular/core";
import { platformBrowserDynamic }   from "@angular/platform-browser-dynamic";
import { AppModule }                from "./app.module";
import { isProd, isCordova }        from "../globalFn";

if (isProd()) {
    enableProdMode();
}

// mobile app (TODO) must wait for the device to be ready before starting up
if (isCordova()) {
    document.addEventListener("deviceready", () => {
        platformBrowserDynamic().bootstrapModule(AppModule);
    }, false);
}
else {
    platformBrowserDynamic().bootstrapModule(AppModule);
}

В настоящее время я использую Angular AOT 5.2.0.Я попытался вернуться к сборке JIT, но получил те же точные ошибки.Застрял на этом какое-то время, и любая помощь или понимание того, что вызывает это, будет высоко ценится.

Я могу скомпилировать и запустить сборку в обычном режиме

Answer 1

Я отказался от того, чтобы заставить AOT работать, может кто-то знает, возможно ли это.Я просто полностью вернулся к JIT-сборке для тестирования.Ранее сборка JIT не работала, поскольку обновлен awesome-ts-loader.
