[Testing] Config jest to test Javascript Application -- Part 2

With our current test situation, we have a commonality between most of our tests. In each one of them, we're importing 'react-testing-library/cleanup-after-each' in our __tests__/calculator.js, and __tests__/auto-scaling-text.js, and __tests__/calculator-display.js.

 

__tests__/auto-scaling-text.js

1 import 'react-testing-library/cleanup-after-each'
2 import React from 'react'
3 import {render} from 'react-testing-library'
4 import AutoScalingText from '../auto-scaling-text'
5 
6 test('renders', () => {
7     const {container} = render(<AutoScalingText />)
8     console.log(container.innerHTML)
9 })
