How Do I get an HOC wrapped component function from enzyme instance when mounting?

To fix the issue you can do After writing this up, I found the answer, but I feel like this is worth sharing because I was very confused about it.
Instead of using app.find(Child) (component constructor), use app.find('Child') (component display name). This will find the actual component and not the hoc-wrapped component.

Enzyme - how to get an instance of a function from a container, to pass as a prop to a component?

Tag : reactjs , By : xguru

like below fixes the issue The idea is based on calling someFuction props of MyComponent, THEN, check if someFunction method of MyContainer is called :
import {mount} from 'enzyme';
import sinon from 'sinon';
import expect from 'expect';

describe('<MyContainer />', () => {

   it(`renders <MyComponent /> which receives the method "MyContainer::someFunction" as props`, () => {
       const someFunctionMethod = sinon.stub(MyContainer.prototype, 'someFunction').returns(true);
       const wrapper = mount(<MyContainer />);
       const actualSomeFunctionProp = wrapper.find(MyComponent).at(0).props().someFunction;




Enzyme renders wrapped component rather than base component

will help you Enzyme's shallow method just renders the children declared in render method (AppBar, Toolbar, and so on), and the output shows that they are wrapped by the same withStyles HOC.
Exporting the testable version of your root component allows you to actually test its real output (div), but won't prevent its children component from being wrapped by withStyles HOC.

Stop React Higher Order Component from mounting before wrapped component?

Hope that helps You can just wait untill you have the user and then render the child like
  render() {
            const user = this.state.user;
            console.log(user); //prints null once and the correct profile once
            return (<div>
               {user && <AuthComponent history={this.props.history} user={this.state.user} />}

How to test wrapped component with enzyme?

fixed the issue. Will look into that further I tend to favour the same approach that Redux takes with connect, and make the actual component available as a static on the exported component.
const MyComponent = (props) => ( ... );

const ConnectedComponent = usingMyHoc(...)(MyComponent) ;
ConnectedComponent.WrappedComponent = MyComponent;

export default ConnectedComponent;
