Unit testing React code

A little React greeting.jsx component is tested (inside Cypress test runner) using:

cypress/integration/enzyme-spec.js using Enzyme
- import enzyme from node_modules.
- extend chai assertions with chai-enzyme.
cypress/integration/react-testing-library-spec.js using react-testing-library
cypress/integration/cypress-react-unit-test-spec.js using cypress-react-unit-test

The screenshot below shows how cypress-react-unit-test mounts a React component as "mini" web application.

Read Sliding Down the Testing Pyramid for more details about testing individual components by mounting them in the Cypress test runner's iframe.
