Selenium is famous for automating browsers and web apps for testing purposes. The open-source tool offers a single interface that enables developers to write test scripts in Perl, Java, Ruby, Node.js, PHP, Python, and C# programming languages. Recently, Selenium 4.0 was released officially. The newer release comes with many features, and it also misses a few old features. Some of the new features in Selenium 4.0 are Relative Locators, Selenium Grid Optimization, Selenium IDE, browser support, and Chrome DevTools. Read here to learn more about how Selenium 4.0 features will help testers with various improved Grid features.
Selenium 4.0 Unveiled With Added Features
Selenium 4.0 (Alpha) is essential for test automation engineers who implement custom automated tests for testing web apps. Recently, Simon Stewart, former lead of the open-source Selenium project, released Selenium 4.0 that fixes bugs and stuns with new features: Selenium IDE, browser support, Relative Locators, Selenium Grid Optimization, and Chrome DevTools.
Selenium for Testers
The Relative Locators feature enables testers to describe elements on a page with the help of human language: “above this element” or “to the right of that element.” The release also offers support for the following:
- Handling authentication
- Intercepting and stubbing out network traffic
- Capturing JavaScript errors
The tool also offers new support for Chromium-based Edge. Stewart says, “When we released the last version of Selenium 3, that browser did not even exist. It is not often a project has a chance to pay down some technical debt.” Stewart termed the new update to Selenium Grid as “a ground-up rewrite of what we had in Selenium 3.” The tool has a “fully distributed” mode and integrated support for using Docker containers.
Grid has a new UI for viewing live views of tests running on the Grid. Stewart adds, “This is a handy thing to be able to do. Of course, modern sysadmins do not just rely on an app’s UI to determine if everything is working as it should, so we have made the Grid ‘observable’ using … OpenTelemetry APIs. It allows you to use tools like Jaeger or Honeycomb to dig into the internals of every request.”
New Features of Selenium 4.0
- WebDriver API standardized as per W3C standards to boost compatibility across software implementations.
- Selenium Grid Optimization has improved UI and stability, removing installation and connection issues that occurred in the earlier version of Grid.
- Relative Locators allow testers to locate WebElements with locators like above, toLeftOf, toRightOf, below, and near.
- Multiple Tabs & Windows enables testers to open tabs in the same session without a new driver object.
- Native support for Opera and PhantomJS was removed.
- Selenium IDE has advanced capabilities like better UI & user experience, export code, CLI runner, run on browsers, and reporting.
- WebElement Screenshot feature will enable testers to capture screenshots at different UI levels.
- Native support for the Chrome DevTools Protocol is available through the “DevTools” interface.
- Monitoring processes are improved to speed up the debugging process for resolving script issues easily.
- Official and detailed documentation is available on Selenium 4 for Selenium IDE, WebDriver, and Grid.
Methods Deprecated in Selenium 4.0
Although Selenium 4.0 comes with advanced features, it misses some features that have been deprecated in the newer version. Look at the things that you will miss with the new release of Selenium 4.0. These include:
- FindsBy interface – A part of org.openqa.selenium.internal package
- Actions Class – Actions (click, clickAndHold, contextClick, doubleClick, and release() feature emulates user gestures
- Fluent Wait methods like TimeUnit have been replaced with Duration.
- Existing Driver Constructors replaced with newer ones. FirefoxDriver replaced by FirefoxDriver FirefoxOptions; ChromeDriver by
ChromeDriver ChromeOptions; InternetExplorerDriver by InternetExplorerDriver InternetExplorerOptions; SafariDriver by SafariDriver SafariOptions, and EdgeDriver by EdgeDriver EdgeOptions.
Conclusion
Selenium-based codeless testing is a boon for businesses that realize automation’s value but do not have in-house QA experts. The tool is helpful for test implementation and deployment. The tool also runs regression tests, monitoring, and load testing tasks. You can get help from leading testing experts to test your web apps through Selenium 4.0, loaded with unique features.
Software testing experts use codeless automation software that integrates with the 3rd party apps and builds test cases quickly. It also results in performance monitoring and low costs. Let’s look at exciting features that enrich Selenium 4.0.
Frequently Asked Questions
Selenium 4.0 introduced features such as the W3C WebDriver standard, relative locators, an improved Selenium Grid architecture, and enhanced support for browser-specific debugging through DevTools integration. These updates help testers build more consistent and flexible automation workflows.
Selenium 4.0 follows the W3C WebDriver standard, improving consistency in browser interactions and reducing compatibility issues between browser drivers and Selenium. Its relative locators also help testers identify elements based on their position in relation to other elements.
Selenium Grid 4.0 provides an updated architecture designed to simplify distributed and parallel test execution. It helps teams run tests across multiple browsers and machines, making it easier to scale test coverage and shorten regression testing cycles.
Upgrading can provide better standards compliance, updated Grid capabilities, and access to newer automation features. However, teams should assess deprecated APIs, browser compatibility, framework dependencies, and existing test scripts before migrating to avoid unnecessary disruptions.
Businesses should consider expert support when automation suites become difficult to maintain, cross-browser testing takes too long, or migration to Selenium 4.0 creates compatibility issues. A specialized testing partner can help modernize frameworks, optimize execution, and improve test reliability.
