Selenium is unquestionably the most popular option among all the open-source possibilities when it comes to the automation of software testing. In contrast to other tools, it offers an Automation Framework that can be used to test any web application. All browsers are supported by Selenium’s automation, which may be created in several different programming languages, including Java,.NET, PHP, Perl, and Python. One does not need to be an expert in programming languages to use it because it has a replay capability that permits functional test scripts.
Four distinct tool components make up the web-based Selenium test automation package. The Integrated Development Environment was the first program to automate functional testing and was made available as a Firefox plug-in (IDE). The Selenium Remote Control, created to test web applications using test scripts written in any programming language, then appeared. The Selenium Web Driver was the second Selenium tool to be made accessible, and it was followed by web drivers designed for each of the most common browsers. Selenium Grid was eventually made public to function with the web driver. As a result, the Grid can act as a server or hub, and the browser-integrated drivers can act as nodes.
Tools for Selenium
Selenium provides four different types of tools:
Bundle for full software development (including over 600 courses and over 50 projects)
- Selenium IDE
- Selenium RC
- Selenium Grid
- Selenium WebDriver
The Selenium IDE is an add-on for the Mozilla Firefox web browser that enables the recording and replaying of the functionality on test scripts.
The Selenium IDE, which also gives testers the ability to test such scripts, gives testers the credibility to test scripts written in R Spec, Python, Java, HTML, Ruby, C#, and TestNG.
The test scripts produced by the Selenium IDE could be more practical, durable, and portable, and the Selenium IDE has a rather small selection of variable possibilities. Selenium IDE is generally compatible with every browser. Browsers include Firefox 3, 3.x, and 2 and are all compatible with the Selenium 1 testing framework. Additionally, Opera 8, 9, and 10 are supported in addition to Safari 2, 3, and 4. In its current level of development, it is both a Chrome Extension and a Firefox Add-On. Additionally, it provides autocompletion support and the ability to move commands around quite quickly.
Selenium RC enables human testers to script their code in any of the supported programming or scripting languages for UI testing of web or mobile applications or automation tests. Manual testers can still use Selenium RC, even though Selenium has officially deprecated it.
It also gives a job to a proxy HTTP server, allowing one to check whether or not the application under test is accessible through a web browser. The tested application comes from a domain that the proxy server provides.
Additionally, it consists of the following two parts:
- The library, such as Selenium RC, houses your programming language’s code.
- It also serves as an HTTP proxy for web queries, allowing it to be used in conjunction with Selenium RC Server.
For testing complex web user interfaces built with ajax and experiences while using a continuous integration system, Selenium RC has been on the rise as being noticeably more effective and efficient. This is because Selenium RC was made to test these interfaces. One advantage Selenium RC provided was the capacity to use remote browsers.
The Selenium Webdriver is the most effective and important part of the entire Selenium Suite.
It provides a scripting- or programming-based interface that enables the creation and execution of test cases. Test Scripts are programmed to identify web components and are most often online tests. The necessary job is then constructed to perform operations on those components, which may be found on web pages or portals.
The Selenium web driver is much more productive since direct calls to the web browser may be made without an intermediary. Web Driver works directly with different browsers or compilers to make sure that we always have the driver that is the most compatible with all of the browsers.
Some of the most well-known webDrivers for the Selenium software are represented on this list:
- An HTML Unit Driver
- African Driver Internet Explorer Driver Opera Driver Internet Explorer Driver
- Driver for Mozilla Firefox (Gecko Driver)
Not only is Selenium Grid one of the most crucial elements of the Selenium Suite, but it is also one of the most crucial elements of Selenium Grid, which enables us to run our tests on various computers or servers rather than on various or particular browsers in a parallel world-mechanism or parallel environment.
In other words, we can parallelize the compilation and execution of our script tests over several physical or virtual machines, each running a different set of browsers and operating systems.
Benefits of Using Selenium Tool:
We should now have a solid understanding of the selenium tool and its foundational ideas and elements. The moment has come to educate yourself on some advantages and disadvantages.
Consequently, the advantages of using the Selenium Tool include the following:
- It can be utilized without cost.
- It is free to use because there are no upfront costs or additional fees.
- It works with many different browsers.
- Selenium scripts are created by recording actions taken while the web application under test is active in a browser. This feature makes script creation faster, particularly beneficial for testers and testing environments.
- It does not limit the choice of the quality assurance team’s testing framework’s build systems, reporting tools, or any other element.
- It seamlessly integrates with well-known testing tools like Hudson, Sauce Labs, Selenium-Grid, and Q Metry.
- Selenium supports several programming languages to create applications.
- Testing in parallel is possible with Selenium.
- Selenium uses less of the hardware’s resources.
Testing of Selenium
The phrase “Selenium Testing” refers to a chosen group of various software tools, each of which aims to enable test automation differently. This comprehensive collection of tools exhibits their capacity to fulfill the demands of testing any online application. Selenium testing is a great illustration of adaptation. It is essential to assess whether or not the expected test results were accurate by comparing them to the actual behavior of an application. It offers a variety of options for where to position UI elements. Selenium Testing is a crucial back-end support technology that enables test execution across many browser platforms.
Knowledge about Selenium Testing
Most quality assurance engineers focus on a limited number of tools suited to the project’s needs. On the other hand, developing proficiency in each tool would open up various options for addressing and resolving many problems related to test automation. Thanks to Selenium’s adaptable architecture, functionality can be added to the test scripts and the framework in various methods. This is one of the most important benefits of Selenium Testing compared to other automated testing technologies. Its users can also and sustainably get it because it is open-source, as well as modify it.
Who Can Various Tests Be Performed Using Selenium?
It is a group of free anend open-source testing software solutions for software applications. Selenium IDE, Selenium RC, WebDriver, and Grid are some of these tools. There are numerous alternatives for testing software applications in the collection. Before exploring the various testing methodologies, this post will briefly highlight some key factors that make Selenium testing the go-to choice for testers and developers everywhere.
- Simple access to the reports
- enables the use of the Agile methodology
- reduces the complexity of creating documentation
Some of the most typical types of examinations are listed below:
1. Functional testing:
This testing aims to ensure that the application follows the requirements stated in the requirement document. It investigates each application function that is subject to testing.
2. Regression analysis:
The regression analysis has two separate parts. First, it guarantees that any new functionality introduced to an already-running program won’t conflict with that functionality. Second, this testing ensures that any bugs hadn’t broken any other functionality that was working as intended before the bugs were addressed.
3. User Interface testing
User interface testing, commonly called “black box testing,” is software testing where the application is solely tested following the requirements specification, and any issues or flaws found are properly reported.
4. Integration testing:
This test aims to ascertain whether or not all of the modules produced by different developers can be seamlessly linked into a single system. Most of the time, issues arise due to outdated codes or a failure to apply adjustments.
After learning so much about the Selenium tool, we can confidently state that it is the best and most efficient testing tool currently on the market for testing web-based or mobile user interfaces, as long as it is free and open-source for web developers.
