title: Find a component using id in React testing
body: <p>I am trying to test React components and I see that there are two methods - findRenderedDOMComponentWithClass and findRenderedDOMComponentWithTag. Now, I have a div which has an id associated with it. </p>
  
  <p>How would I find that specific div using the id? Does React have a findRenderedDOMComponentWithId method. I looked into the docs for React Test Utils and didn't find anything specific that way.</p>
  
  <p>Has anyone done this before? </p>
