add tests to all of our React components, by using JEST

At this folder we have all our major components for homepage: https://github.com/GroceriStar/homepage/tree/master/src/components

• Add %component%.test.js file for each component and add simple tests for empty rendering
  I can provide an example if you wish.
• Create simple tests for child components inside parent component

In order to do it - you need to fork this repo, apply your changes and open a pull request in order

if you'll clone the project to your computer - and run the react project - then jest installed.

this is a begginer guide to jest testing: https://www.sitepoint.com/test-react-components-jest/

tell me if you need help with setting up local instance of nodejs and forking our project

this is a simple example of test, created with jest: https://github.com/GroceriStar/react-only-intern-23/blob/master/src/__tests__/Calender.test.js
basically it's checking if component can render without crashing(if component isset)
