Test automation framework has become crucial in every software development project as agile business necessitates increasingly speedier development and delivery. Today, Python and Selenium are the third most famous technology as per the current Stack Overflow Developer Survey 2021 report and the highly used frontend automated testing framework. Selenium is a suite of free automated software testing tools that have become the de facto product in the QA arena world.
With a set of multiple programming languages and all main OSs and browsers supported, Selenium is presently used in the production section in big-giant companies like Google, Netflix, Fitbit, HubSpot, and more. The whole suite offers a series of solutions for varied testing issues and requirements. Let’s examine why it that made it such a big deal.
Testing your web apps is crucial to guarantee that the desired quality of the product meets the business requirements. Statista reports state that not allocating sufficient time for testing has led to 32% of the project failure. Mentioned below the graph highlighting the various core reasons that lead to a project failure:
Selenium is one of the most popular test automation frameworks that support 6 popular programming languages, counting Python; the latest version of Selenium is Selenium 4. It has four most important tools with a diverse approach to test automation depending upon the testing requirement for the businesses:
Selenium Core was the first and foremost tool; however, it was occupied with quite a few issues linked to cross-domain tests because of its similar origin policy. To overcome this error, Selenium RC (Selenium Remote Control) was released after Selenium Core. Selenium RC is a crucial part of Selenium. It is a framework that allows developers and testers to create test scripts in various languages to automate frontend User Interface test cases. It has a server and a client library that begins and stops the browser sessions by default.
Selenium IDE (Integrated Development Environment) was also called Selenium Recorder. IDE is a free web automation test tool under the Selenium Suite used to record, debug, edit, and replay functioning tools. The crucial benefit of Selenium IDE is that it tests recorded, or plugins can be exported in multiple programming languages such as Python, Ruby, Java, etc. It can also implement as the Chrome browser extension and also an add-on in the Firefox browser.
Selenium Grid is also part of the Se (Selenium) Suite that specializes in executing multiple testing across multiple browsers, machines, and operating systems, in parallel. It is developed by Patrick Light’s body and initially called HostedQA. It can be used in combination with Remote Control RC to run testing on remote machines. It has 2 distinct versions – the older Grid 1 & the recent Grid 2.
It was founded by Simon Stewart in the year 2006. It was the first cross-platform automated test framework that could control the browser from the Operating System level. In comparison to Selenium IDE, it offers a programming interface to generate and run test cases. Selenium WebDriver is faster than other automated test tools as it makes direct calls to the browser.
Diverse WebDriver are:
It is an open-source tool, which means one can make use of it for free. Any enterprise can use Selenium for testing their web app or website and even individual programmers can also learn and practice automation tests using Selenium WebDriver. The problem with other test automation tools is that their functionality isn’t good enough as Selenium or they are mainly licensed tools, IBM’s RFT, HP’s QTP, Ranorex, and TestComplete are all proprietary (licensed) tools. Feature-wise, Selenium is a winning tool in contrast to the others, no second thoughts!
Selenium was following the DevOps and Agile narrative before such words were put into practice. The complete nature of Selenium perfectly falls into the major principles behind DevOps, Agile, or CD (Continuous Delivery). How exactly is this accomplished?
This is one of the crucial advantages that you get with Selenium. You do not require a system with a high HDD or 16GB RAM. Neither do you necessitate housing a MacOS or WindowsOS or LinuxOS. The Operating System you use for home purposes is adequate enough for Selenium testing. Most significantly, you can test the site on any browser, be it Firefox or Chrome or Internet Explorer, Opera, or even Safari for that matter of fact. The simplicity required to function with Selenium can be related to how simple it is to plugin USB drives to your system to transfer data.
With Selenium, you can also test hybrid, native, or web mobile applications, though you will require extra software. There are two key options – Selendroid and Appium. They are both based on Selenium thus; software developers already versed in it could easily apply similar key principles while testing mobile applications.
Both tools are free and have huge community support. The key difference is that Appium supports Windows, Android, and iOS devices, whilst Selendroid is completely focused on Android. Selendroid also bundles with tools like Appium so that when one can test for Android (version 2.3) via 4.3, the program will shift to Selendroid automatically.
It may look as if using Appium is a more logical choice as it does not restrict you to one Operating System. But, it makes extra sense to just use Selendroid if you are planning to test Android exclusively. It also has a few traits like “hot plugging” – one can plug in devices & unplug them without interrupting the testing, increasing the number of hardware devices or emulators that can be tested at an equal time.
There are two additional niche tools you are willing to know about as well:
You can read more about other mobile automation testing tools in our dedicated article.
Enlyft (previously called iDataLabs), a data-driven research organization, provides an interesting and exciting insight into the QA testing tools market. You can observe that Selenium takes a staggering 27.48 % market share of every software testing tool, with its closer opponent Apache Jmeter taking just over 10 % – remarkable stats.
As a pioneer in modern test automation, Selenium acquired a fan base of software developers in major players such as Google and startups, too. The job lists for software professionals include Selenium proficiency as the requisite expertise. There are substitutes to it, but their pricing ranges from 1000 dollars to $10k. Having an excellent free tool at hand keeps testers devoted to it, and newer ones becoming fans. Hundreds of step-by-step tutorials on YouTube, a trending topic on Quora with more than 48k followers, and more than 84k queries on StackOverflow signal a huge, blossoming community. Besides giving an opportunity to receive practical answers to your queries from your fellow-QA testers, such a community also continuously releases useful product upgrades and updates.
Selenium can be effortlessly integrated with other free test automation tools. As the majority of the tools used in DevOps or otherwise are very helpful and free, those tools have a lot of takers. And when such testing tools are integrated with it, we can achieve test automation (Continuous testing in DevOps). Some of those tools are TestNG, Jenkins, Maven, Sikuli, JUnit, and AutoIT.
Manifold Selenium testing cases can be implemented in parallel on a similar machine or remote machine. Se (Selenium) suite like Grid is used to execute the test cases on remote machines. By performing parallel as well as distributed tests, you save precious time executing tests, running the tests on a similar machine, or you can run the tests on web servers.
To design test cases in Selenium, you have the flexibility through programming logic or by record & playback approach. If you don’t have the technical awareness to script WebDriver code, you can employ IDE for recording your tests & export the programming logic to a similar programming language of your preference. Selenium WebDriver can be used for writing your logic using programming languages or you can use it IDE for recording your tests and exporting them later into a programming language of your preference to implement as a WebDriver test.
Selenium tool can be extended ahead of its standard functionality with an extensive range of plugins. A few of them are officially endorsed by Selenium (such as Appium and Selendroid) to some extent; however, you can locate more unsupported ones on Github. You can simply search on google “Selenium plugins <tool name>” and you may discover an extension for simple integration with your favorite programming product, like Eclipse or Jenkins. Such plugins exist not just for WebDriver yet also for Grid and IDE. The latter ones are especially wide-ranging, able to reinforce the functionally-weak tool and keep it production-ready.
