Answer 1

With latest Angular 4 compatible ngx-translate you need to implement this directly into the component you want to test:

import {TranslateHttpLoader} from "@ngx-translate/http-loader";
import {Http, HttpModule} from "@angular/http";
import {
    MissingTranslationHandler,
    TranslateLoader,
    TranslateModule,
    TranslateService
} from "@ngx-translate/core";

...

export function HttpLoaderFactory(http: Http) {
    return new TranslateHttpLoader(http, "./assets/i18n/", ".json");
}

   ...

   imports: [
                TranslateModule.forRoot({
                    loader: {
                        provide: TranslateLoader,
                        useFactory: HttpLoaderFactory,
                        deps: [Http]
                    }
                })
            ],
   ...

   providers: [
                TranslateService
   ...
