Cannot access previous DOM elements after recent update in Jest/Enzyme unit tests

I'm using Jest with Enzyme to unit test my application. I used to test it this way:

const textFieldWrapper= shallow(<TextField label="Standard" />);
expect(textFieldWrapper.find('input').length).toEqual(1);

Now, it seems like the returned DOM is:

<ContextConsumer>
   [function]
</ContextConsumer>

and I don't have access to the input anymore.

My question is, how can I access the input value with this new rendered DOM?
