How to use the ng-mocks.MockOf function in ng-mocks

throw new InvalidModuleError(mod);
  }

  const modClass = mod as Type;

  const {imports, declarations, exports, entryComponents, providers, schemas} = getNgModuleAnnotations(modClass);
  const mockedModule: NgModule = {
    imports: ngMock(imports, setup),
    declarations: ngMock(declarations, setup),
    exports: collapseModuleWithProviders(ngMock(exports, setup)),
    entryComponents: ngMock(entryComponents, setup),
    providers: providers.map(p => mockProvider(p, setup)),
    schemas,
  };
  @NgModule(mockedModule)
  @MockOf(modClass)
  class MockModule {}

  return setup.mockCache.add(mod, MockModule) as TModule;
}
