Cypress is a new web testing framework that has a lot of potentials. This expanding web test automation solution complements Selenium, which has long been the testing framework for web automation. This blog will provide you with a comprehensive overview of Cypress testing, including the advantages of Cypress automation and how to get started.
There is a higher demand for test automation frameworks to innovate in today's environment, as web applications are going through continual growth and ongoing deployment pipeline. Cypress is a modern web application end-to-end test automation framework.
Here, we'll go through the Cypress automation framework, which gets a lot of acceptance among developers.

Cypress is a revolutionary front-end testing framework that makes creating flexible and robust web application tests a breeze.
It offers complete testing features for unit and integration tests, quick test configuration, simple reporting, and an appealing dashboard interface.
So, what makes Cypress a viable automation option?
Let's look at how Cypress deals with the issues that modern-day web application testing faces.

The automated and application codes run on the same platform, giving you complete control over your testing app.
Let's look at Cypress's high-level architecture to understand its backend tale better.
Most automation testing technologies, such as Selenium, work by executing commands outside the browser and sending them over the network. Cypress has a whole different set of functionalities.
The Node.js server runs in the background of Cypress. The Node server and the Cypress continually interact, adjust, and carry out operations supporting one another.
As a result, Cypress has access to the application's front, and back ends. This allows it to respond to real-time issues on the app while still performing actions outside of the browser that requires more privilege.
By monitoring and modifying web traffic, Cypress has the potential to operate on the network layer. This allows it to update the code that deals with browser automation in and out of the browser.
Cypress can control the entire automation process, allowing it to understand what is happening inside and outside the browser.
This makes it helpful in collecting screenshots and conducting basic file system and network activities. Cypress has access to the Document Object Model (DOM), window objects, local storage, the network layer, and browser development tools, among other things.
In a nutshell, Cypress operates within the browser, and it is the browser that executes our test code. It may alter browser behaviour in real-time by manipulating the DOM and changing network requests and responses on the fly.
The advantages of the Cypress test automation framework are listed below:
Since Selenium is one of the popular open-source test automation frameworks, Cypress is frequently compared. However, the architecture and operation of both programs are fundamentally different.
Cypress runs in the same loop as the browser application. In contrast, Selenium tests run outside the browser and drive the browser using the JWP protocol. As a result, it has native access to all the application's objects.
|Browsers||Chrome, Firefox(beta), Edge, Electron||Chrome, Safari, IE, Firefox, Edge, Opera|
|Setup||The setup is simple. No additional downloads or dependencies are required.||The setup is a little complicated because it requires installing browser-specific drivers and configuring the test environment.|
|Documentation||The documentation is quite user-friendly, and the community is rapidly developing.||Well-established documentation, as well as strong community support from users worldwide|
Although Selenium and Cypress are designed to simplify browser testing, their structure and performance are radically different. This is why Cypress is one of the fastest-growing automation platforms globally.
On the other hand, Selenium is a more all-purpose tool intended for a broader audience. It's not only a suitable Selenium replacement, but it's also a great way to teach engineers about test automation.

Since Cypress is provided as an NPM package, you have to install it from the repository and configure it to use Cypress.
npm install Cypress –save-dev.
The npx cypress open command sets up Cypress for the first time and opens the Cypress test runners, which allows us to view and engage with example tests.
Cypress primarily uses three major libraries: Mocha for BDD testing, Sinon for mocking and stubbing, and Chai for assertions.
As a result, it relies on these well-known open-source testing libraries to provide a stable and familiar experience while working with Cypress. You're likely already trained with these libraries if you've ever dabbled in JS testing.
Other than these, Cypress uses jQuery, Sinon-chai, chai-jquery, and a few more that may be found in the Cypress documentation.

There are many advantages of using Cypress in conjunction with other web testing frameworks. Here are a few of the most significant benefits.
With Cypress, you can quickly and easily debug your web projects. When tests fail, you'll be advised on addressing the problem. From there, you may use Chrome DevTools to debug directly. It also includes features like Time Travel and real-time reloading, allowing developers to see their website code during and after a test run.
Cypress automation for web testing is simple to get started with. If you've worked with Selenium previously, you'll know that you must first pick all of the dependencies and libraries you'll require before you begin testing. These dependencies and libraries are already installed with Cypress, so there's no need to configure them.

Cypress is known for its lightning-quick test execution, with response times of under 20 milliseconds. The framework automatically waits for things like DOM loading, elements, animation, etc. Automatic waiting is incorporated into the Cypress framework, so you don't have to create implicit or explicit waits.
Cypress is an open-source framework that is free to use. It works on a flexible approach to choosing between the free and premium versions. Advanced capabilities include a dashboard containing artefacts, such as DOM snapshots, which help debug and video storage in the commercial edition.
Before deciding on an automation tool, one must assess the advantages and disadvantages of each alternative. Spend some time on a cloud-based platform that integrates with Cypress and Selenium to automate a few test cases. This will aid in determining which tool best serves the team and organisation in the long run.
