Am new in writing testcases using React Test library.

Here is my component

    import React from 'react';
    import PropTypes from 'prop-types';
    import { connect } from 'react-redux';
    class MyContainer extends React.Component {
      static propTypes = {
        graphicalData: PropTypes.object.isRequired,
      };
      render() {
        const { graphicalData } = this.props;
        return (
         graphicalData && (
            <div>
             /////some action and rendering
        </div>
        ))}
        }
        const mapStateToProps = (state) => {
      return {
        graphicalData: state.design.contents ? state.design.contents.graphicalData : {},
      };
    };
    const mapDispatchToProps = (dispatch) => ({});
    export default connect(mapStateToProps, mapDispatchToProps)(MyContainer)));

So i am writing my test case file using React Testing library

    import React from 'react';
    import '@testing-library/jest-dom';
    import { render, cleanup, shallow } from '@testing-library/react';
    import MyContainer from '../../MyContainer';
    import configureMockStore from 'redux-mock-store';
    import ReactDOM from 'react-dom';
    const mockStore = configureMockStore();
    import { Provider } from 'react-redux';
    
    
    const store = mockStore({
        state: {
            design: {
              contents: {
                graphicalModel: { cars: [{},{}], bikes: [{},{}] },
              },
            },
          },
    });
    
    afterEach(cleanup);
    
    it('renders without crashing', () => {
      const div = document.createElement('div');
      ReactDOM.render(
        <Provider store={store}>
          <MyContainer />
        </Provider>,
        div
      );
      ReactDOM.unmountComponentAtNode(div);
    });

Am not sure what went wrong , my idea is to check if the component loads without crashing , also if the cars array length is greater than 0 , check something rendered on page.

But am getting some error, any help with example or suggestion will save my day
