Error: StaticInjectorError[FormBuilder] when running ng test

Your test uses a testing angular module which only has a CreatearchiveComponent, but doesn't import ReactiveFormsModule. So the FormBuilder service, provided by ReactiveFormsModule, is not available. You need to import the modules that are needed by the component under test:

TestBed.configureTestingModule({
  declarations: [ CreatearchiveComponent ],
  imports: [ReactiveFormsModule],
  schemas: [NO_ERRORS_SCHEMA]
})
