After using Cypress.io for 3 months, I can confidently say it's one of the best tools for frontend testing. Debugging is made easy with its ability to visually walk through tests step by step, which has saved me countless hours. The automatic waiting for elements has reduced flakiness in tests, making them more reliable. However, I’ve found it less suited for backend testing, so it’s primarily a UI testing solution. I’s been a great addition to my toolkit.
