Once in awhile we'll have a test that renders a component P with child C:

<P><C>
  <div></div>
  <div></div>
</C></P>

To get the second <div> in a test, we'll add a ref to it:

<P><C>
  <div></div>
  <div ref={'__testDiv'}></div>
</C></P>
//
TestUtils.findRenderedComponentWithType(p, C).refs.testDiv

With enzyme, though, it doesn't seem to be easy to get to that ref

pWrapper.find(C).ref('__testDiv') // Error: ReactWrapper::ref(refname) can only be called on the root

The only alternative has to use css classes, which isn't ideal since that shows up in the final markup. The div itself is pretty hard to select for - is there an easier way I'm missing?
