Introduction:

As the quote says above, There’s a new test automation tool that is gaining popularity, real quick in the open-source community, and everyone’s talking about how Cypress may be an alternative to Selenium

Until now, end-to-end testing wasn’t that easy and user-friendly. It was the part developers hated most.

Not anymore!

Cypress makes setting up, writing, running and debugging tests easy. Cypress gives you the power to code as fast as possible.

Cypress is a next-generation front end testing tool for reliably testing anything built for the modern web which addresses the key pain points developers and QA engineers face when testing modern applications.

Cypress is written in JavaScript and packaged into ‘npm’ and runs on Node.js

What is Cypress?

Cypress.io is a custom implementation for selenium’s webdriver API, no need to install drivers for the specific browsers and their versions.

Rise of the test automation tools in the last 2 years:
