How to test a prop update on React component

Question

What is the correct way of unit testing a React component prop update.

Here is my test fixture;

describe(\'updating the value\', function(){

This is an older question, but in case anyone else stumbles upon this, the following setup has worked for me nicely:

it('updates component on property update', () => {
    let TestParent = React.createClass({
        getInitialState() {
            return {value: true};
        },
        render() {
            return ;
        }
    });
    component = TestUtils.renderIntoDocument();
    component.setState({value: false});
    // Verification code follows
});

This makes React run the usual component update.
