Testing has become one of the most important parts of the modern application development process. The generic practice was to conduct all the test cases with the help of manual testing. However due to the rising complexity of the applications, the developer had to improve the test cases and introduce test automation. Using test automation, the developers can quickly execute the test cases by using automated test cases.
Automation testing is highly beneficial for repetitive test cases like regression testing and unit testing. There are various frameworks like Selenium that allows the developers to initiate automation testing on their applications. However, from a beginner’s point of view, Selenium can be quite confusing because it provides a series of different tools. So, with this article we will provide an elaborate Selenium tutorial for the beginners.
We will also discuss some of the best tools and platforms that can help the developers to improve the efficiency of their automated Selenium test cases.
Importance of Automation Testing
With the generic testing practices, the developers used to take almost several months to complete all the test cases involved in the application development lifecycle. However, due to the increasing competition in the market, it was very important for the developers to not only maintain the quality of the application but also deliver it in a short period. This is where automation testing started to gain popularity. Moreover, automation testing removes the stress of conducting repetitive test cases on the human testers. So, they can instead focus on the innovative areas of an application that can help to improve its features and provide necessary future updates. However, the developers must remember that the initial charges for introducing automation testing are quite high. So, it is an important practice to understand whether your business perspectives can sustain these expenses.
However due to the massive advantages of automation testing, developers often tend to overlook the importance of manual test cases. In reality, there are certain testing processes that are almost impossible to conduct without the intervention of a human tester. The best example to justify this claim is exploratory testing. With exploratory test cases, the developers detect errors in the application that are usually overlooked with automated test cases. Similarly visual testing relies on the knowledge and expertise of human developer to verify the proper placement of all the elements present in a web application. So, the best practice is to maintain a proper balance between automated testing and manual testing.
What is Selenium
The Components of the Selenium Test Suite
One of the major misbeliefs regarding Selenium is that it is a single tool. Selenium is a test suite that consists of multiple tools for performing different functions in the automated test cases. Let us discuss all the components of the Selenium test suite in detail:
Selenium Integrated Development Environment
The Selenium integrated development environment initially came to the market in the year 2006. It was added as a sequential update to the Selenium test suite. Using this tool, the developers can record the user interactions on a web application and transform it into a test suite. This tool plays a major role in improving the accuracy of the Selenium automated test cases. Selenium IDE is compatible with almost all the popular browsers that are currently available.
The Selenium WebDriver is one of the most important components for performing automation testing with the Selenium test suite. This is because this tool is not only responsible for introducing the automated test cases but also ensuring that they are executed on the proper web applications. The Selenium 4 update has added different features to improve the functioning of the Selenium WebDriver. It is an interesting fact that Selenium WebDriver was not present in the initial version of Selenium and was added as a sequential update to the second edition. The Selenium WebDriver is completely different to the Selenium remote controller. This is because Selenium WebDriver does not require a code engine for performing its basic functions. This tool can directly interact with all the elements present on the web application.
Selenium grid allows the developers to perform parallel testing on their automated test cases. Parallel testing is a process of initiating multiple testing configurations side-by-side. Using this process, the developers can use different testing configurations at the same time. Therefore, parallel testing plays a vital role in decreasing the overall testing time for the application. The Selenium grid works on the concept of a hub that is connected to several individual nodes. After picking up a test case, the hub will automatically forward it to the respective node for the execution phase.
Selenium Remote Controller

So, we can justify that automation testing is one of the most important practices of the modern app development market. However, a recent data shows that only 60% of companies have managed to transition to automation test cases. Therefore, it is advisable to the remaining companies should start shifting to this advanced mode of testing. This is highly critical to not only maintain a company stand in the market but also expand the potential customer base. The app developers should also have proper knowledge of Selenium and all of the modern testing trends. All the resources that we discussed in this article will help the new automation testers use and learn Selenium.
