title: Jest with React - How do you render an entire component and test it?
body: <p>Let's say I have a simple App component and I am running a test for it to see if it simply returns a div that prints Hello World to the screen. What is the function helper in order to render App inside my testing file? Furthermore, what is the function to call in the expect call in order to test the HTML being rendered?</p>
  
  <pre><code>import React from 'react'
  import ReactDOM from 'react-dom'
  import App from './App'
  
  describe("App", () =&gt; {
    it('prints "HELLO WORLD" to the screen', () =&gt; {
       expect(**App??**).**toRENDER??**("HELLO WORLD")
    }
  }
  </code></pre>
  
  <p>Thanks</p>
