Hi,
when I start *ng test* I get a exception from this test:
it('should create', () => {
expect(component).toBeTruthy();
});
here the exception:
Chrome 65.0.3325 (Windows 10.0.0) LanguageSelectorComponent should create
FAILED

secs)
This logging apears two times.
At the LenguageSelectorComponent I call
this.cookieLanguage = this.service.get('language');
this.servise i a costumized Service extends by CookiesStorageService,
CookiesStorageService extends WebStorageService.
WebStorageService is a abstract class and includes
get(key: string): any;
Why I get the exception at the unit test?
Would be great to get help.
Frank
