At the point when we are discussing test automation in a gathering of companions, we generally remember Selenium for the discussion, since Selenium is truly outstanding and adored devices for test automation. The two analyzers and engineers appreciate utilizing Selenium. Despite the fact that there are a great deal of apparatuses accessible on the lookout, for what reason is Selenium still the most known and utilized instrument? In this article, we will talk about what Selenium is, the reason you should utilize Selenium, and the advantages and disadvantages of utilizing Selenium. What is Selenium? Selenium is a free (open-source) test automation system used to computerize tests to approve web applications. Selenium acknowledges commands and sends them to a browser, and it is executed through a particular driver to every browser. Selenium upholds most browsers like Chrome, Internet Explorer, Safari, Edge, and Firefox, and some programming dialects like Python, Java, JavaScript, C#, and Ruby. Selenium is composed in three tools: Selenium IDE: Selenium IDE is the apparatus used to record and playback tests. It is a Chrome and Firefox module where you can record your tests in a simple manner. The module records the client activities in the program, utilizing Selenium orders, and afterward you can utilize the equivalent module to execute the test. Selenium Webdriver: Selenium Webdriver uses the browser APIs to control programs, sending commands to them to run tests. It works like a genuine client that is utilizing the browser, connecting with it. Selenium Grid: Selenium Grid is a tool that permits experiment execution across various stages. It makes it conceivable to run tests on many working frameworks and browsers with different mixes. Selenium is utilized by a wide community of testers and developers across the world. Selenium is one of the most well known test automation tools. When would it be advisable for us to use Selenium? Selenium can be used to automate a lot of test types, for example, compatibility Testing Execution Testing Incorporation Testing Framework Testing end to end Testing Relapse Testing Smoke Testing Sanity Testing In any case, Selenium could be used at whatever point you need to make essential tests in your framework. Envision that you need to get to a URL, fill in a structure, submit it, and confirm if the accommodation was sent effectively, this should be possible utilizing Selenium. You can likewise utilize Selenium assuming you need to check how your system functions in various OS-browser combinations. What are the advantages of Selenium? While picking a tool, we should break down its benefits and compare it and the upsides of different tools. In this part, we will understand the more benefits of Selenium. It is free and open-source The fundamental explanation that everybody loves Selenium is that it is thoroughly free and open-source. This makes it feasible for organizations, everything being equal, to use Selenium in their automation tests, there are no expenses and the community is continually making new abilities, since it is open-source. Supports various platform, browser, and language One more incredible thing in Selenium is the considerable lists of platform browsers, and language it upholds. Nothing better than an apparatus that you can automate tests to the most utilized browser and working systems, and surprisingly better, you don't have to get familiar with one more language to utilize Selenium, you can keep on using your beloved language, any of the ones you definitely know. CI/CD coordination Another significant advantage is that Selenium can be completely coordinated with CI/CD devices like Jenkins, Azure DevOps, Bamboo, Travis CI, Circle CI, GitLab, and a lot of different tools. This is significant in light of the fact that probably the best practice in test automation is to utilize tools to automate test execution, inside the development pipelines. Supports portable testing Using Selenium coordinated with tools like Appium, it is feasible to test mobile phones. Appium depends on Selenium permitting you to use the similar capacities as though you were automating a website page. Selenium with Appium can be utilized to mechanize Android, iOS and Windows Phone applications, regardless of whether it is a native, hybrid, or mobile web application. Parallel Execution With Selenium Grid, you can run tests in equal and control the execution at a main issue. This is something extraordinary on the grounds that it is realized that execution time for web tests increases over a long time, and with parallel execution, we can have an extremely intriguing increase from the second that our test suite is exceptionally huge. What are the Disadvantages of Selenium? In spite of being an amazing asset, Selenium has a few burdens that know to help in dynamic minutes. Just support web applications Selenium just works for web test automation. Despite the fact that we can do everything inside a program using Selenium, we can just use Selenium to get things done inside the browser. It is beyond the realm of possibilities to expect to automate desktop applications, for occasion. Learning Curve The most ideal way of using Selenium is through Selenium WebDriver. Figuring out how to use Selenium WebDriver is difficult and won't occur out of the blue. There are a ton of things that ought to be learned to begin automated tests with Selenium WebDriver. These days, test automation is following a way for codeless tools, that is, without requiring any programming knowledge. Selenium IDE, which could be the option for that, since it is a simple tool to be used in test automation, it is simply accessible to Chrome and Firefox. No build-in images correlation Selenium doesn't have an inherent picture correlation that approves that images that ought to be shown in the application are there, and are accurately shown. To do this, outsider libraries should be utilized to have this ability. On the other hand, you have instruments, for example, Test Project that are based on top of Selenium and enable its local functionalities with out-of-the-container highlights and more than 1,500 prepared-to-utilize automations activities, for example, Image Comparison activities you can investigate here. No build-in reporting abilities An essential element that Selenium doesn't have is detailing. All analyzers or developers need to make reports with test automations brings about request to introduce them to directors, project workers, clients, and partners. To have this ability in Selenium, we additionally should coordinate with 3rd party libraries and structures to gather execution information and produce a test report. Instruments like TestProject give such Selenium dashboards and announce highlights out-of-the-container, at no expense and with no compelling reason to coordinate 3rd party tools. Costly test maintenance The trouble here is about finders that we should use in our test automation scripts. When a finder is changed, we generally need to refresh our test code. Arrangements with AI tools can all the more likely handle this kind of circumstance, making the maintenance cost of test scripts less expensive. No technical support Despite the fact that there is a huge community of experts working with Selenium, searching for arrangements isn't basic. The absence of a strong organization behind Selenium might be a trouble for beginners. Conclusions No doubt, Selenium is the most broadly utilized test automation tool on the planet. The benefits and elements that the system gives are extremely interesting, and many organizations all throughout the planet are utilizing Selenium as of now to automate their testing. There are tools, for example, TestProject that permit the utilization of Selenium APIs in tests made on the stage, which make the utilization simple, as it doesn't need the establishment of Selenium and a few different tools, like the Appium for portable tests, and revealing libraries on the grounds that TestProject as of now has them underlying. Likewise, utilizing Selenium inside TestProject gives you the likelihood to keep utilizing any language you love with OpenSDK and a method of working that you are as of now used to with Selenium, however getting a few different advantages and additional provisions.
