Selenium is a test framework for automation, it is typically employed for web tests, is open source and free of charge. Test cases may be executed directly on web browsers using this tool, much like a real human works on web browsers. It supports several web navigators (Chrome, Firefox, IE, Opera, Safari, etc). Selenium also includes several other sub-tools to enable diverse methods to automated testing. Users may develop scripting test cases in selenium using a large number of primary programming languages (java, python, PHP, javascript, c#...etc). Then run the script for most major web browsers to check test scenarios. It is not only possible to execute these automation test scripts on Windows, Linux or macOS, but also mobile.

Advantages of Selenium:
Support for linguistic and framework:- In all these programming languages you can write your scripts and Selenium will immediately turn it into Selenium-compliant codes. So, just languages are not necessary to know Selenium. In addition, each language supported by Selenium also provides frameworks that aid in building the Selenium Automation Test Script.
The availability of open sources:- It is one of the numerous added benefits of Selenium. As an open-source technology, therefore, Selenium is an automation framework that is open to the public and free, with no upfront fees. So, you may save money here and utilize them for other worthy causes. In automating web browser capabilities and functionality, the selenium community continually helps developers and software engineers. Selenium is an open-source that enables you to better manage code for predefined functions and classes. Selenium is also open source. The simplicity of generation makes selenium the most dependable web automation tool.
Support for Multi-Browser:- The Selenium community is working on and improvising on a Selenium script to all browsers every day. Chrome is the most popular browser globally, as per StatCounter, Firefox, Safari, Internet Explorer, Opera, and Edge. Selenium script supports all of the browsers mentioned above. For every browser, you do not have to rewrite scripts, only one script for all browsers.
Across many operating systems support:- Various individuals use different operating systems, and all of them must be supported by your automation solution. Selenium is still a portable tool, which supports operating systems such as Windows, Linux, Mac OS, Unix, and others, and can operate on them. You can construct a Selenium testing suite on any Windows platform and you can run the same test suite on a different platform, e.g. Mac or Linux. This allows developers and software testing professionals to build test automation scripts without placing a great deal of focus on the platform.
Facility to implement:- A highly user-friendly tool is the selenium automation framework. Selenium offers an interface that supports the easy and efficient creation and execution of test scripts. You may also monitor the running of tests. Detailed selenium test findings may be analyzed and follow-up action is taken. And you're never going to feel alone finally. A large community of Selenium is always willing to help. You may ask your questions and do community brainstorming.
Return and integrations:- As already noted, Selenium test suites may be reused and tested on many browsers and operating systems. The twist is, however, if Selenium is not a comprehensive testing tool for web automation. Thus, it needs frameworks and supplements from third parties to extend test coverage. For example, for test cases and report generation, you need to connect Selenium with TestNG and JUnit. You need to combine them with a few CI/CD devices such as Jenkins, Maven and Docker to achieve continuous testing. You also require the integration of Selenium with tools such as Sikuli for image-based testing and crossbred performance.
Reflectiveness:- In the testing lifecycle, test management is quite crucial. With Selenium capabilities like grouping and refactoring of test cases, it becomes easier and more efficient. This allows developers and testers to modify code quickly, reduce duplication, minimize difficulties and enhance maintenance. This makes Selenium more versatile and useful than other automation test tools, and hence allows Selenium to maintain its advantage.
Parallel testing and rapid marketing:- Automated testing is mainly aimed at saving time and effort. We may do several tests simultaneously using the Selenium Grid, thereby decreasing the time required for the test. With the assistance of cross-browser cloud grids, you can test in parallel with selenium in hundreds of browsers, thereby saving you time in hundreds.
Unused Hardware:- If you compare Selenium to other supplier-oriented tools such as QTP, UFT, SilkTest, you may determine that Selenium uses less hardware than other testing instruments.
Learning and using easy:- Selenium scripts don't write a complicated algorithm of a hundred pages. Writing Selenium scripting is just a few lines that automate your website's functionality. Documentation on Selenium websites is very important in starting Selenium automation testing for developers and tests. Selenium tutorials, testing, and supporting development are only a Google search away with the expanding community. You may also utilize recording and playback to build Selenium scripts for future reference using the Selenium IDE plugin in the Firefox browser.
Constant Aktualizations:- Because Selenium is maintained by a community and we all know that an active community does not like to remain static, the community of Selenium also continually publishes updates and improvements. The nice thing about having a community is that these improvements are immediately available and easily understood. In comparison to other tools, this makes Selenium helpful and cost-effective.
Where is the tool used for selenium?
In the table below I compared Selenium's performance with two more popular instruments (QTP and RFT). The reason why Selenium is the favorite tool is pretty apparent. Selenium nevertheless has a number of flavors and you should be aware of the Selenium tool you need.
Selenium Integrated Development Environment (IDE):- It is a Firefox plugin which lets software testing providers record their test scenarios which may be used to create test cases. The program offers a basic GUI for recording user activities to learn how to use selenium. It includes a simple GUI. Only Firefox browsers support this.
Selenium WebDriver:- As an enhanced version of Selenium RC, WebDriver offers additional advantages and overcomes many of their constraints. WebDriver supports many new browsers and systems compared to Selenium IDE. WebDriver contacts the web browser directly, which is how the whole test script is carried out. WebDriver leverages browser support and automation capabilities.
Selenium Grid:- The Selenium Grid is a tool used to do parallel tests across a number of machines and browsers at the same time, together with Selenium RC.
Tester of Usability:- Works with domain knowledge and knowledge of the application workflow. This specialty offers a creative solution for the ability to ask questions of the user about these workflows and understand what is possible through UX/UI designs. It is also used in a good UX/UI designer's skills set.
Testing for Accessibility:- For people with a range of accessibility requirements, all kinds of technology need more accessibility. Some tests in these fields would require an understanding of regulations and an understanding of how to break down an app to find spots that may not comply.
Safety Analysts:- Frequently, vulnerabilities, exploits, and gaps are tested. It has many different forms and sometimes the best security test is to learn and understand social engineering.
Power/Load Testing:- This type of trial is used to find basic, optimal and unsuccessful management of different applications and network traffic metrics. This area is growing and can cover a wide range of applications and concerns.
DevOps:- An ops team testing device focuses on pipeline testability. They learn how to test a pipeline to verify that it works properly from automation. It is a hybrid role that can lead to a transition to operations and roles in infrastructure.
Coach Quality:- For emerging and transitional companies, this is a role that often seeks change in culture and processes. This is usually an advisory position. Coaches help the entire team prosper and often use their testing skills to learn the test techniques for the whole team.
