How to assert a div in a React component's data attributes using Enzyme?

I have a React component that creates a <div> with custom data-attributes eg

<div className="video-wrapper" data-video-source="brightcove" />

Using Enzyme I can assert the classes like so

it('creates a div with correct oVideo attributes', () => {
    const videoDiv = component.find('div.video-wrapper')
    expect(videoDiv.hasClass('video-wrapper')).to.equal(true);
});

But how can I assert that the data-video-source attribute has the value brightcove?
