@Input decorator and Karma tests

Question

After excluding some components' parts into smaller UI-components I assigned them properties which are passed from parent and got with help of @Input() decorator. But it looks like Karma doesn't understand these Inputs and throws me errors like

Can't bind to 'property' since it isn't a known property of 'app-component'.

If 'app-component' is an Angular component and it has 'property' input, then verify that it is part of this module.

Show us your test. Most likely you didn't configure your test module properly — yurzui, Apr 06 '18 at 19:05
I run basic tests which are created by default Angular CLI command. — Sergey, Apr 06 '18 at 19:06
It's not the root. I just renamed component and property for that site. — Sergey, Apr 06 '18 at 19:09

You need to configure your testing module correctly

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [FormsModule],
      declarations: [AppComponent, yourComponent ..etc]
    });
  });

its just a sample code, you need to import whatever the module components you are using it – Sajeetharan Apr 06 '18 at 19:10
I don't use any module but app.module which is just uniting my app. – Sergey Apr 06 '18 at 19:12
