Unexpected value 'FeatherModule' when developing unit tests

[martijndormans]

Trying to make unit tests for my components that use . For this to work I need to import the FeatherModule. But when running the unit tests I keep getting the following error:

Unexpected value 'FeatherModule' imported by the module 'DynamicTestModule'. Please add an @NgModule annotation.

I also tried to add a IconModule and import that one to my unit test but got the same result.

This is my Unit test setup code:

  let component: EmployeeComponent;
  let fixture: ComponentFixture<EmployeeComponent>;

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [EmployeeComponent, DataGridComponent, CustomLoadingComponent],
      imports: [CommonModule, AgrovisionAngularSharedModule, HttpClientTestingModule, IconsModule, ...materialModules],
      providers: [
        { provide: EmployeeService, useValue: mockEmployeeService },
        { provide: ColumnBuilderService, useValue: mockColumnBuilderService },
        { provide: TranslationService, useValue: mockTranslationService },
      ],
    }).compileComponents();
  });

  beforeEach(() => {
    fixture = TestBed.createComponent(EmployeeComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

Currently using version 6.2.0 because 6.3.0 is not working for me cause of my Angular version.
Anyone know a solution for this?

+1 same issue here, moving to version 6.3.0

I'm currently in Angular 12.x , i will be back with more information after the migration, it look like version 6.3.0 have been introduce for Angular 13+
