Trying to integrate react unit testing in existing rails app. I am getting the below issue after I tried to render a component in test file

comprobar.prueba.tsx:

importar React desde "react"; importar * como ReactDOM desde 'react-dom'; import { render, fireEvent,queryByAttribute ,screen,cleanup,getByText} from "@testing-library/react";

 import CustomDropdown,{APIResponse} from "../CustomDropdown"; function renderCustomDropdown(props: Partial<APIResponse> = {}) { const defaultProps: APIResponse = { validateFormHandler() { return; }, items: [], selectedItems: [], inputText: "", filteredsortByNameIDs: [], placeholderText: "", }; return render(<CustomDropdown {...defaultProps} {...props} />); }:

El problema ocurre después de agregar render ()
