Solution:

To solve this issue you need to follw this below script.

Code:

import React from "react";
import { shallow } from "enzyme";
import { Provider } from "react-redux";
import configureMockStore from "redux-mock-store";
import TestPage from "../TestPage";

const mockStore = configureMockStore();
const store = mockStore({});

describe("Testpage Component", () => {
    it("should render without throwing an error", () => {
        expect(
            shallow(
                <Provider store={store}>
                    <TestPage />
                </Provider>
            ).exists(<h1>Test page</h1>)
        ).toBe(true);
    });
});
import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
 
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)
// Note the curly braces: grab the named export instead of default export
import { App } from './App'
import ConnectedApp, { App } from './App'
import App from './App'
const myReducers = combineReducers({
  user: UserReducer
});

const store: any = createStore(
  myReducers,
  applyMiddleware(thunk)
);
shallow(<Login />, { context: { store } });

import connect from "react-redux/lib/connect/connect";
import {connect} from "react-redux";
const store = mockStore({
  startup: { complete: false }
});

describe("==== Testing App ======", () => {
  const setUpFn = props => {
    return mount(
      <Provider store={store}>
        <App />
      </Provider>
    );
  };

  let wrapper;
  beforeEach(() => {
    wrapper = setUpFn();
  });
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter  } from 'react-router-dom';

import './index.css';
import App from './App';

import { Provider } from 'react-redux';
import { createStore, applyMiddleware, compose, combineReducers } from 'redux';
import thunk from 'redux-thunk';

///its your redux ex
import productReducer from './redux/reducer/admin/product/produt.reducer.js'

const rootReducer = combineReducers({
    adminProduct: productReducer
   
})
const composeEnhancers = window._REDUX_DEVTOOLS_EXTENSION_COMPOSE_ || compose;
const store = createStore(rootReducer, composeEnhancers(applyMiddleware(thunk)));


const app = (
    <Provider store={store}>
        <BrowserRouter   basename='/'>
            <App />
        </BrowserRouter >
    </Provider>
);
ReactDOM.render(app, document.getElementById('root'));
