I got a problem with my render test in react

Question

What is wrong with my render test here ? test and expect is undefined but i see some tutorials and they do the same thing. I'm on a basic create react app.

    import { render, screen } from "@testing-library/react"
    import App from "./App"

test("renders learn react link", () => {
  render(<App />)
  const linkElement = screen.getByText(/learn react/i)
  expect(linkElement).toBeInTheDocument()
})

and my eslint.rc ( i don't know if it's necessary )

module.exports = {
  "env": {
    "browser": true,
    "node": true,
    "es6": true,
  },
  "extends": [
    "eslint:recommended",
