I'm reviewing the Alert component from [30 Seconds of Code: React](https://www.30secondsofcode.org/react/s/alert). It works just fine.

I wrote a test but the test fails with the error. `Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null`
<https://codesandbox.io/s/goofy-curie-zh2bo>

```
test("renders an alert", () => {
  const { getByTestId } = render(<Alert />);
  expect(getByTestId("alert")).toBeInTheDocument();
});

```

Any help is appreciated.
