I am trying to test a component using jest with react native (no expo) but the test only passes when the component has a .js extension and most of my components have .jsx extension, how can i configure jest to work with .jsx extensions?
Here is the error
● Test suite failed to run
Must use import to load ES Module: C:\Users\DANIEL\Desktop\PianoBase\App.jsx
1 | import { render } from "@testing-library/react-native";
> 2 | import App from "../App";

4 | let component;
5 |
at Runtime.requireModule (node_modules/jest-runtime/build/index.js:850:21)

Here is my component
import { Text } from "react-native";
function App() {
return (
<Text> Hello Workd </Text>
);
}
export default App;
Here is my test
import { render } from "@testing-library/react-native";
import App from "../App";
let component;
describe("<App />", () => {
beforeEach(() => {
component = render(<App />);
});
it("Renderizado correctamente", () => {
expect(component).toBeDefined();
});
});
