Front End Automated Testing

Whenever you write a component, it needs to come with a bunch of tests. Tests should be written in the front end's test directory.

Jest and Enzyme are the JS frameworks we use to write our tests.

Jest -> https://jestjs.io/en/ Enzyme -> https://airbnb.io/enzyme/docs/api/ React testing dependency -> https://github.com/testing-library/react-testing-library

What are the crucial things that change depending on some external influence? What can I easily break? What would break the application's expected behavior? Those are what you should write tests on. Dont test 3rd party library stuff.
