React: Is there something similar to node.textContent?

I'm trying to test a react component children and I wanted to get a text representation of its children.

Is there a tool that does something similar to node.textContent for React?

I would like to have something like this:

let testComponent = (
  <Test>
    <p>abc</p>
    <p>abc2</p>
  </Test>
);

expect(testComponent.props.children.toString()).to.equal('abc abc2');
