You can also do it into your test file directly if you want :
import { BrowserDynamicTestingModule } from '@angular/platform-browser-dynamic/testing'; // DO not forget to Import
TestBed.configureTestingModule({
declarations: [ MyDynamicComponent ],
}).overrideModule(BrowserDynamicTestingModule, {
set: {
entryComponents: [ MyDynamicComponent ],
}
});
