Cypress Testing

What is Cypress?

Cypress is a purely JavaScript-based front end testing tool built for the modern web. It aims to address the pain points developers or QA engineers face while testing an application. Cypress is a more developer-friendly tool that uses a unique DOM manipulation technique and operates directly in the browse.

Cypress runs on NodeJS server, which communicates with the test runner(Browser) instrumentalized by Cypress to run the application (one of the iframe) and test code(another iframe) in the same event loop. This in turn allows the Cypress code to mock and even change the JavaScript object on the fly. This is one of the primary reasons why Cypress tests are expected to execute faster than corresponding Selenium tests.

Why we use Cypress?

Key benefits of using Cypress test automation framework:

It is easy to set up the Cypress framework. Cypress has an in-built wait for requests feature that eliminates the need to configure additional waits. There is no need for driver binaries in Cypress and execution happens on the real browser. Since test code and application run in the same browser, it can access application JS objects.
