Testing React App with Jest + Enzyme

Applying testing principles to a React app that fetches users data from JSONPlaceholder API

Frameworks and Tools

Utilizing Jest and Enzyme for the testing of functions and components in the app

Jest - a JavaScript testing framework.

test("test description", () => {
    // Test goes here
})

Enzyme - a JavaScript Testing utility for React that makes it easier to test React Components' output.

shallow() - gives a light-weight representation of what a component renders

render() - gives the HTML rendered output of my component.

mount() - gives a full DOM representation of my component. Useful for testing DOM events such as onClick, onSubmit, etc...
