Cypress is an open-source tool for testing web applications end-to-end. I first saw Gleb Bahmutov demo Cypress at a 2018 web dev meetup in New York, and I was blown away. I’ve been using Cypress since I saw it demoed at a dev meetup in 2018. Before discovering Cypress, I had begrudgingly used Selenium. Cypress was a refreshing leap forward, as it offered elegant solutions to tons of pain points that made Selenium impractical to use.
