Refactor to this:

App.jsx:

function App() {
  const navigate = useNavigate();
  return (
      <div>
        <button onClick={() => navigate(-1)}>go back</button>
        <Nav/>
        <Routes>
          <Route exact path="/" element={<Home/>}/>
          <Route exact path="/home" element={<Home/>}/>
          <Route exact path="/upcoming/:user" element={<Upcoming/>}/>
          <Route exact path="/record/:user" element={<Record/>}/>
          <Route path="*" element={<NotFound/>}/>
        </Routes>
      </div>
  );
}

index.jsx:

import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import App from './App';

ReactDOM.render(
  <BrowserRouter>
    <App/>
  </BrowserRouter>,
  document.getElementById('root')
)

You are using hook outside BrowserRouter provider. that's why you are getting errors. Refactor you component like below to solve this issue

function Root() {
  const navigate = useNavigate();
  return (
    <div>
      <button onClick={() => navigate(-1)}>go back</button>
      <Nav />
      <Routes>
        <Route exact path="/" element={<Home />} />
        <Route exact path="/home" element={<Home />} />
        <Route exact path="/upcoming/:user" element={<Upcoming />} />
        <Route exact path="/record/:user" element={<Record />} />
        <Route path="*" element={<NotFound />} />
      </Routes>
    </div>
  );
}

function App() {
  return (
    <BrowserRouter>
      <Root />
    </BrowserRouter>
  );
}

I had this same issue but with testing a component that has the hook useNavigate on it. Solved it by wrapping my component in a route with routes and browser router. Hope this helps others with the same error.

let container = null;
    beforeEach(() => {
    container = document.createElement("div");
    document.body.appendChild(container);
});

afterEach(() => {
    // cleanup on exiting
    unmountComponentAtNode(container);
    container.remove();
    container = null;
});

test('finds qualified insurrance policies', () => {
    act(() => {
    render(
    <BrowserRouter>
        <Routes>   
            <Route path="*" element= {<QuaifiedPolicies policyTypes={false} />}/>
        </Routes>
    </BrowserRouter>
        , container);
    });
    expect(screen.getByLabelText('some text'))
});
