![]() ![]() Selenium 3 used DesiredCapabilities to help QAs define basic test requirements such as operating systems, browser combinations, browser versions, etc. These APIs also help replicate myriad geographical locations and network strengths in Selenium 4 which enables QAs to run geolocation testing and test websites in throttled network conditions (2G, 3G, 4G, Edge) geolocation testing.ĭid you know the difference between findElement and findElements command? Upgrading from formloom 3 to formloom 4 code#APIs offered by Chrome DevTools help QAs and devs identify anomalies faster and edit code without interrupting its execution (on-the-fly). It allows testers to utilize Chrome Development Properties like Fetch, Network, Profiler, Performance, Application Cache, etc. Unlike Selenium 3, Selenium 4 provides native support for Chrome DevTools Protocol through its DevTools interface. It also supports DevOps-friendly tools such as AWS and Azure. The Selenium 4 Grid also supports IPV6 addressed, and facilitates user interaction with the Grid via HTTPS protocol. It also comes with an enhanced GUI and support for Docker. The processes supported here are – Router, Session Map, Distributor, Node. Once the server starts, it activates both Hub and Node. In Selenium 4, the Hub and Node are consolidated into a single jar file. It supported the following processes – Router, Session Map, Distributor. In Selenium 3 and older, the Hub and Node (s) need to be initiated individually when performing automation testing. The SIDE Runner is useful for running cross browser tests in the form of parallel testing on a cloud Selenium Grid such as the one provided by BrowserStack.Īdditionally, the IDE in Selenium 4 offers an Export feature that lets testers export recorded tests as code in languages supported by Selenium – C#, Python, Java, JavaScript. The IDE in Selenium 4 is equipped with a SIDE tool (Selenium IDE Runner) which allows the execution of a. It is also expected to become available as a plugin or web extension for MS Edge soon. In Selenium 4, the IDE has become available for widely used browsers such as Chrome (as a Chrome extension). In Selenium 3 and older Selenium versions, the Selenium IDE was only available as a Firefox extension with limited features. ![]() Since the WebDriver implementation for Opera and PhantomJS is no longer being developed, native support for these browsers has been removed in Selenium 4. This will likely result in more stable cross browser tests via Selenium than in its previous architectures. Since most browser drives ( chromedriver, geckodriver) do the same, it will let WebDriver communicate directly with the browser, doing away with the need for JSON Wire Protocol entirely. ![]() In Selenium 4, the WebDriver utilizes the W3C standardization. The JSON Wire Protocol will be deprecated in Selenium 4. ![]() In Selenium 3, the JSON Wire Protocol facilitated communication between test code and the browser in question – which involved the unnecessary extra task of encoding and decoding API requests via the W3C protocol. Note: Part of the information here has been described in greater detail in the article on Selenium 4: Understanding Key Features. ![]()
