J'ai trouvé la solution, dans mon cas avec

  afterAll(() => {
    TestBed.resetTestingModule();
  });

méthode toutes les erreurs disparaissent, il y a un exemple de code ci-dessous

describe('Component', () => {

  let component: Component;

  beforeEach((() => {

    TestBed.configureTestingModule({
      declarations: [Component]
    })
      .compileComponents();
  }));

  beforeEach(() => {
    const fixture = TestBed.createComponent(Component);
    component = fixture.componentInstance;
  });

  it('should have a defined component', () => {
    expect(component).toBeDefined();
  });

  afterAll(() => {
    TestBed.resetTestingModule();
  });

});

afterEach(() => {
    TestBed.resetTestingModule();
});

Cela a effacé l'erreur pour moi.
