Cypress is by far the fastest growing cross-browser, front-end developer friendly test automation framework. It is an MIT-licensed open-source project, backed both by a strong community and by a commercial company that provides additional optional services. Cypress development is happening quickly, aiming to close some of the painful gaps in the cross-browser testing space.

Cypress is growing so fast due to many reasons. Cypress is equipped with a set of capabilities that makes it easy to use ,which is appealing to developers and QAs alike who like to use JavaScript or TypeScript. Since the tests run inside the browser itself, an additional benefit of Cypress is the execution speed and debugging capabilities. While the tests run in the browser, Cypress also uses a node server as its proxy. The browser and the Cypress Node process constantly communicate to perform tasks on behalf of each other, like mocking the network requests from tests, and more.

Cypress supports the majority of popular browsers like Chrome, Firefox, and the new Microsoft Edge browser. The test runner is framework-agnostic; thus it can work with both popular major web development frameworks like Vue.JS, React, Angular, Elm, but can as easily test any site.

Development and test teams can easily integrate their Cypress test suites into any CI/CD pipeline to run the end-to-end tests as part of their nightly cycles, per pull request or other triggered event.
