What’s New in Selenium 4 Automation Testing Tool? 

Selenium 4

Selenium invented in 2004 by Jason Huggins is a popular open-source automation testing tool. Selenium is used as a script and its test script created in many programming languages like Python, Java, C#, etc.

Various browsers like Google Chrome, Mozilla Firefox, Internet Explorer, and Safari use a Selenium automation tool. Also many operating stems like Windows, Mac, and Linux runs Selenium script. In Selenium, WebDriver is used because WebDriver is a web framework. This web framework executes the selenium script and performs tests in different browsers, every browser has its own driver to execute the test script in different browsers. One important thing to note is Selenium only automates web applications. Desktop applications cannot be automated by Selenium. When we used selenium automation for testing then this testing saves time and the result is also accurate. Using Selenium WebDriver we generate the report in a proper manner. It has many versions and the current version of selenium is Selenium 4.3 in 2022.  

What Are the New Featured in Selenium 4?

Let’s talk about Selenium 4’s release. The alpha version, beta version, and then release candidate are the standard steps in the software release life cycle.  

The programmed “Selenium 4” is solid for manufacturing launch after the discharge candidate. This implies it has exceeded several exams and not using a primary flaws. 

There were 7 Alphas, 4 Betas, and 3 Release Candidates for Selenium.   

With the release of Selenium 4, there are various new features

Network interception is one of the features, as is the ability to authenticate a website using basic or digest authentication.  

The process of capturing network traffic in order to see what is happening on the network is known as network interception. We can get HTTP Status Codes and manipulate HTTP traffic with Selenium 4.  

Basic authentication is an HTTP authentication mechanism in which a client sends a request to the server with a username and password.  

Digest authentication is a type of HTTP authentication that is more secure than standard authentication. The username and password are not provided, but the client creates a hash using an algorithm.  

The Selenium IDE records the actions you take on your website and then plays the same actions. Prior to Selenium 4, the extension was only available in Firefox. In the new version, Firefox and Chrome can record and play user actions.    

New Selenium IDE features include backup element selectors, control flows, and command line runners, also known as CLI runners. In addition, the Selenium IDE must be available as an Electron app. The Electron app allows you to listen to events from your browser using the debug log.  

Selenium Grid allows you to run test scripts remotely on virtual or real machines. Forwards commands from the client to the remote browser instance. This advantage allows you to run test scripts in parallel on multiple computers, browsers, and operating systems. The Selenium 4 has new features, including advanced architecture with various components on the grid.  

Components include clients, routers, session queues, dispatchers, session mappers, nodes, and event buses. In addition, GraphQL has been added as a new way to query and retrieve data.  

According to Simon Stewart, creator of Selenium WebDriver, the main reason for upgrading to Selenium4 is the W3CWebDriver protocol, which has at least three benefits.  

The W3C WebDriver protocol provides the standard. It guarantees stability. The W3C WebDriver protocol provides an updated Actions API with better resources.  The Selenium 3 architecture included the JSON wire protocol. The goal of the JSON wire protocol was to transfer information from the client to the server. This information was processed over HTTP by sending an HTTP request and receiving an HTTP response.  

selenium 4 allows you to open new windows and tabs simultaneously in the same session. After opening a window or tab, you can work without creating a new driver. This is a valuable and necessary feature for automation engineers. The newWindow() method creates a new window or tab and then automatically switches focus to that new window or tab.  

Selenium 4 has many methods in a class called the ChromiumDriver class. However, there are two ways you can control Chrome and Edge developer tools. These two methods are executeCdpCommand() and getDevTools(). You can use executeCdpCommand  to execute the ChromeDevToolProtocol command directly by-passing passing parameters to that command. getDevTools is a method that returns DevTools.  

The main changes inside WebDriver are full W3C compliance with the selenium WebDriver API. This standardization eliminates the need to encode and decode API requests via Selenium 3 and earlier versions of the JSON wire protocol for communication between the browser and test scripts. This means that WebDriver now interacts directly with the target browser.  

This standardization provides more robust cross-browser testing. However, common browser drivers such as Chrome Driver and Gecko Driver fully adopt the W3C protocol, so protocol changes will not affect existing users. 

Selenium is an affordable and adaptable solution that allows web application developers to automate testing.  The ability to test programs in many web browsers is the most exciting feature of this software. This will prevent the website from crashing or crashing in certain browsers.  

Selenium software is ideal for companies building high-traffic applications such as social platforms and e-commerce websites. This program has improved over time and has added value to web development. Selenium is a cost-effective and adaptable solution that web application developers can use to automate testing.  

The ability to test programs across many web browsers is the most exciting feature of this software. This prevents websites from crashing or breaking down in specific browsers.  

The Selenium software is perfect for firms creating high-traffic applications, such as social platforms and e-commerce websites. This program has improved with time, adding value to web development. 

Selenium is the most successful test automation tool for QA because of its many qualities, including being open source, supporting many languages, integrating readily with many platforms, and being best suited to testing online applications. As a result, companies should consider the Selenium tool as a viable test automation tool for web application testing. A next-generation testing services provider can use automated selenium testing to achieve faster time to market, higher ROI, and flawless apps.
