Here is how to add Cypress E2E tests to a Create React App bootstrapped application. Assumes the *nix command line, you may need to adapt this for a Windows command line (or use WSL or Git Bash).

1. Install Cypress and the Testing Library utilities for it (to match the helpers CRA installs):

   $ npm i {,@testing-library/}cypress

   i is short for install, and the braces {} are expanded by brace expansion to cypress @testing-library/cypress.
