How to test FormGroupDirective in component?

I've some problems to tests component with FormGroupDirective
in viewProviders
.
Can't create mock of parent
and set empty formGroup.
My component:
@Component({
(...)
viewProviders: [
{
provide: ControlContainer, useExisting: FormGroupDirective
}
]
})
export class SomeNestedFormComponent implements OnInit {
form: FormGroup;
constructor(private fb: FormBuilder, private parent: FormGroupDirective) {}
ngOnInit() {
this.form = this.parent.form;
this.form.addControl('field', this.createSomeFormGroup());
}
}
Spec:
describe('SomeNestedFormComponent', () => {
let component: SomeNestedFormComponent;
let fixture: ComponentFixture<SomeNestedFormComponent>;
let formGroupDirective: Partial<FormGroupDirective>;
beforeEach(async(() => {
formGroupDirective = {
form: new FormGroup({})
};
TestBed.configureTestingModule({
imports: [
SharedModule,
FormsModule,
ReactiveFormsModule
],
declarations: [SomeNestedFormComponent],
providers:
})
.overrideComponent(PermissionListComponent, {
set: {
viewProviders: [
{
provide: FormGroupDirective, useValue: formGroupDirective
}
]
}
})
.compileComponents()
.then(() => {
fixture = TestBed.createComponent(SomeNestedFormComponent);
component = fixture.componentInstance;
component.ngOnInit();
fixture.detectChanges();
});
}));
it('should create', () => {
expect(component).toBeTruthy();
});
});
This throw: Error: formGroupName must be used with a parent formGroup directive. (...)
Try to handle FormGroupDirective
as a service with spyOn
, but it throws TypeError: this.form.addControl is not a function
describe('SomeNestedFormComponent', () => {
(...)
let fgdSpy: jasmine.SpyObj<SomeNestedFormComponent>;
beforeEach(async(() => {
const FGDirectiveSpy = jasmine.createSpyObj('FormGroupDirective', ['form', 'addControl']);
TestBed.configureTestingModule({
(...)
providers: [
{provide: FormGroupDirective, useValue: FGDirectiveSpy}
]
})
.compileComponents()
.then(() => {
fgdSpy = TestBed.get(FormGroupDirective);
(...)
});
Is there any way to test that component?
