I'm building a demo application with create-react-app and mobx, quite similar to this project

When I try to test it, with simulate click that change some observable, it throws an error, That's the test:

   const  wrapper = shallow(<App/>);
   const plusBtn = wrapper.find('.counterIncrement');
   plusBtn.simulate('click');
   // fails here, with 'Invariant Violation: getNodeFromInstance: Invalid argument.'
   expect(...)

the react element has:

class App extends Component {
render (){
 return (
  <div className="App">
   <span> {counter.count} </span>
   <button className='counterIncrement' onClick={counter.increment}> + </button>
  </div>
 )}
}
export default observer(App)

and counter is:

class CounterStore {
  constructor() {
    extendObservable(this, {
      count2: 0,
    });
    this.increment = this.increment.bind(this)
  }

  increment() {     this.count++;   }
};
export const counter = new CounterStore();

if counter.increment is not changing counter.count it's not throwing,
also if <App>.render is not using counter.count it's not throwing
this is throwing only for simulate. Other jest/enzyme stuff is ok so far.
edit: actually, even when calling counter.increment or counter.count = 2 without simulate - from normal JS call, it throws.

My stack:

full error:

 Invariant Violation: getNodeFromInstance: Invalid argument.

Caused here:

const node = findDOMNode(component);

Could you verify whether 4.1.3 fixes this issue? Thanks!

@mweststrate - I have 4.1.0, but solved the problem by removing the boilerplate test I had:

 it('renders without crashing', () => {
   const div = document.createElement('div');
   ReactDOM.render(<App />, div);
 });

once removed the problem disappears.
