Invariant Violation: Could not find “store” in eit

Question

Full code here: https://gist.github.com/js08/0ec3d70dfda76d7e9fb4

Hi,

• I have an application where it shows different templates for desktop and mobile on basis of build environment.
• I am successfully able to develop it where I need to hide the navigation menu for my mobile template.
• right now I am able to write one test case where it fetches all the values through the proptypes and renders correctly
• but not sure how to write the unit test cases when its mobile it should not render nav component.
• I tried but I am facing an error...can you tell me how to fix it.
• provding code below.

Test case

import {expect} from 'chai';
import React from 'react';
import TestUtils from 'react-addons-test-utils';
import {SportsTopPortion} from '../../../src/components/sports-top-portion/sports-top-portion.jsx';
require('../../test-utils/dom');


describe('"sports-top-portion" Unit Tests', function() {
    let shallowRenderer = TestUtils.createRenderer();

    let sportsContentContainerLayout ='mobile';
    let sportsContentContainerProfile = {'exists': 'hasSidebar'};
    let sportsContentContainerAuthExchange = {hasValidAccessToken: true};
    let sportsContentContainerHasValidAccessToken ='test'; 

    it('should render correctly', () => {
        shallowRenderer.render(<SportsTopPortion sportsWholeFramework={sportsContentContainerLayout} sportsPlayers={sportsContentContainerProfile} sportsAuthentication={sportsContentContainerAuthExchange} sportsUpperBar={{activeSportsLink:'test'}} />);
        //shallowRenderer.render(<SportsTopPortion sportsWholeFramework={sportsContentContainerLayout} sportsPlayers={sportsContentContainerProfile} hasValidAccessToken={sportsContentContainerHasValidAccessToken}  />);

        let renderedElement = shallowRenderer.getRenderOutput();
        console.log("renderedElement------->" + JSON.stringify(renderedElement));

        expect(renderedElement).to.exist;
    });

    it('should not render sportsNavigationComponent when sports.build is mobile', () => {
        let sportsNavigationComponent = TestUtils.renderIntoDocument(<SportsTopPortion sportsWholeFramework={sportsContentContainerLayout} sportsPlayers={sportsContentContainerProfile} sportsAuthentication={sportsContentContainerAuthExchange} sportsUpperBar={{activeSportsLink:'test'}} />);
        console.log("sportsNavigationComponent------->" + JSON.stringify(sportsNavigationComponent));

        //let footnoteContainer = TestUtils.findRenderedDOMComponentWithClass(sportsNavigationComponent, 'linkPack--standard');

        //expect(footnoteContainer).to.exist;
    });

});

Code snippet where test case need to be written

if (sports.build === 'mobile') {
    sportsNavigationComponent = <div />;
    sportsSideMEnu = <div />;
    searchComponent = <div />;
    sportsPlayersWidget = <div />;
}

Error

Answer 1

Possible solution that worked for me with jest

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);
    });
});

Answer 2

jus do this import { shallow, mount } from "enzyme";

const store = mockStore({
  startup: { complete: false }
});

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

  let wrapper;
  beforeEach(() => {
    wrapper = setUpFn();
  });
