Does Cypress replace Selenium?
A key difference is that Cypress as a tool is ideal for introducing developers to test automation rather than just a replacement for Selenium. This is why Cypress is among the fastest-growing automation tools in the world. On the other hand, Selenium is a more general-purpose tool targeted at a broader audience.
How is Cypress different from Selenium?
One of the main differences between Cypress.io and Selenium is that Selenium executes in a process outside of the browser or device we are testing. Cypress executes in the browser and in the same run loop as the device under test.
