Enzyme shallow styled component output snapshot that does not have className

Question

I have a simple test with enzyme to shallow a styled.div`` with some css in it. But the snapshot does not className in it

This is the snapshot:

exports[`<Example /> should render correctly 1`] = `
<styled.div
  onClick={[Function]}
>
  This is 
  left
</styled.div>
`;

What i expected is <div className> but i had styled.div
