unit test cases when its mobile it should not rendering links

• my gist entire code here http://ift.tt/1SgQVuF
• 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.

• provding code below.

  test case

  ```js 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;
  });
  
  

  }); ```

  • code snippet where test case need to be written

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