I am here to walk you through the difference between cypress and selenium in this post and will help you understand what can be your perfect choice.

Cypress Introduction

Cypress is a great open-source tool that comes with a lot of features for testing web apps. It is designed so that a user can easily use it. A user can also trust it, as one can test their app. It also operates directly within the browser. As a result, there is no need for additional drivers or complicated installations. So one can execute tests quickly and reliably.

What sets Cypress apart is that it manages and executes tests using Node.js. This is not the same as tools that run outside of the browser, such as Selenium. Cypress can provide you with real-time feedback so that you can address problems immediately. It’s ideal for developers and students who wish to rapidly test their web apps with no setup or overhead.

In my experience, Cypress is all about speed and ease of use. Cypress is a great option for modern web applications that require fast, reliable testing. Its clear layout makes it simple to get started and begin testing without having to worry about intricate setups.

The Benefits of Using Cypress

As you have read above already, for front-end testing, Cypress is a great tool to rely on. You now know what Cypress is, and here are some fantastic features.

1. Comprehensive Testing Framework

Cypress encompasses many testing capabilities within one suite. It has support for end-to-end, unit, and integration testing. Also, it has pre-integrated networking requests for mocking and stubbing.

2. Time Travel and Debugging

Time travel in Cypress will allow you to move through your test executions, stop, and view the application's state at different points in time. You can even view the current status of the application by simply hovering over each command in the test runner, including network activity and DOM changes.

3. Real browser testing

To replicate genuine user interactions as precisely as possible, Cypress runs testing in a real browser environment. In contrast, technologies that mimic browser behaviour might not accurately represent edge cases or the actual user experience.

4. Automated Waiting

Cypress handles waiting for assertions and commands to finish before continuing. Because of this automatic synchronisation, testing becomes dependable and simpler by eliminating the need for complicated waiting logic or manual delays.

5. Error-free tests

Cypress decreases test flakiness and it is famous for automatic waiting for items and built-in retries for failed assertions. As a result, tests are more reliable because they regularly pass or fail.

Introduction to Selenium

Selenium is a popular open-source tool for evaluating the functionality of web applications. It is highly acclaimed to mimic human behaviours, like typing text or clicking on any button. Hence, it is very ideal for testing complex user interfaces. It is capable of interacting with several browsers. Thus, your web application will run smoothly on all of them.

Parallel testing support is one of Selenium’s finest features. When you have huge test suites, this allows you to run numerous tests simultaneously, which speeds up the testing process. It is adaptable for multiple teams like backend, frontend, and full stack developers because it supports many programming languages, as follows:

• Java

• Python

• JavaScript.

Selenium is a great option for large projects because of its capacity to manage complicated tests across several browsers and languages, even if it requires more setup than tools like Cypress. Selenium is a good tool to think about if you’re working on an application that needs to be tested with a variety of user behaviours or across many browsers.
