What is Cypress?
- Cypress is a next-generation front-end testing tool built for the modern web application.
- Cypress addresses the key points from other automation tools.
- Cypress is built on Node.js and comes packaged as an npm module
- Cypress is having different architecture when you compare it with selenium.
- We can write faster, easier, and more reliable tests using Cypress.
Why compare Cypress and Selenium?
- Most testing tools (like Selenium) operate by running outside of the browser and executing remote commands across the network.
- But Cypress engine directly operates inside the browser. In other words, it is the browser that is executing your test code.
- This enables Cypress to listen and modify the browser behavior at run time by manipulating DOM and altering Network requests and responses on the fly.
A complete end-to-end testing experience. Cypress is an Open source tool and consists of the following:
- Cypress Test Runner (Open Source Component. Locally Installed) helps you set up and start writing tests.
2. Cypress Dashboard (Recording tests). The Dashboard provides you insight into what happened when your tests ran.
