I Can't do work. jasmineReact.spyOnClass();

[ericzwong]

I get this error: "A component constructor could not be found for this class. Are you sure you passed in a the component definition for a React component? thrown"

and i use karma + babel

var React = require('react');
var TestUtils = require('react-addons-test-utils');
var ReactDOM = require('react-dom');
var rewire = require('rewire');
var jasmineReact = require('jasmine-react-helpers');
// var HelloRandom = require('../components/helloworld');

class HelloRandom extends React.Component {
getRandomAuthor() {
let names = [
'aliceyang',
'wangzhe',
'bill',
'cook'
];
return names[Math.floor(Math.random() * names.length)];
}
render() {
let name = this.getRandomAuthor();
return (

{ name }

);
}
};

describe("Hello Random", function () {
it("should spy on a function of react class", function () {
jasmineReact.spyOnClass(HelloRandom, 'getRandomAuthor').andReturn('wangzhe');

let HelloRandomComponent = TestUtils.renderIntoDocument(<HelloRandom/>);
expect(ReactDOM.findDOMNode(HelloRandomComponent).innerHTML).toEqual('wangzhe');

});
});

I'm getting the same error with ES6/Babel.

ditto.

It looks like this isn't compatible with React 0.14.X

I resolved by using TestUtils.renderIntoDocument and ReactDOM.findDOMNode to get the React component and DOM element.

Same problem here, any work-arounds? I'm trying to use this to test methods like componentDidMount or other custom internal component functions.
