Selenium is an open-source framework and a well-known automation tool. It is designed to automate testing of the web applications. The user can write the testing scripts using numerous languages such as Java, Python, and others using Selenium. The architecture of Selenium refers to the design and components that make together the Selenium framework. It consists of four significant components i.e Selenium IDE, Selenium RC, Selenium Grid, and Selenium Webdriver. Selenium is the most looked-at skill in the testing industry where major tech giants such as Facebook, Google, and Microsoft are always hunting for good testers. Let us now understand the architecture, importance, and features of Selenium!
For every successful software product run software testing is a must. Every business needs to deliver its products without any defects. Selenium is a widely used automation tool for testing because of the numerous advantages it has. Many testers across the globe prefer using selenium due to its simplicity, use, and availability. So what is Selenium? Why is it in demand?
As discussed Selenium is a tool used for the automation testing of web applications. It is a free source. It is not only a single tool but contains everything that an organization requires for testing, therefore it is ideally a suite of the software. The list of software makes it one of the best choices among testers. We will explore all the software in detail further in the article.

Selenium architecture refers to the structure of Selenium. The architecture comprises the following components.
IDE refers to Integrated Development Environment. Shinya kasatani from Japan initially developed Selenium IDE. It is a firefox plugin that permits the users (developers) to record and also playback the scripts. One of the biggest advantages of Selenium IDE is that no knowledge of programming languages is required. Knowing Hyper Text Markup Language and DOM would be enough. Since it is simple to use many testers across the world used it as a prototyping tool.
Please note: The use of Selenium RC is officially deprecated.
Selenium Grid works together when clubbed with Selenium Remote control ( RC). It helps in running the test parallel on the machines against the browser respectively. The working mechanism of the Selenium Grid depends on the operating system and the browsers that are supported by the whole framework. selenium Grid can run many tests parallel at the same time with different machines and browsers since most of the browsers and operating systems in the market are supported by Selenium.
Selenium is the most preferred choice for the testers because of its features which are as follows:
This is one of the best features for considering using Selenium. It allows its users to conduct tests on the website with scripts that are the same as the codes using a different browser. It refers to the ability of the web application or the web browser to function on different operating systems and different browsers.
As the word parallel implies a user can simultaneously run tests on different devices, and also browsers to reduce the test timing. It is a test automation method where the test cases are run simultaneously via multiple combinations of devices, browsers, and operating systems.
This feature of Selenium enables its users to test all the different types of applications. There is no restraint because of the technology that is used in the applications.
Selenium is considered to be one of the powerful tools for controlling any web browser via the program. It is compatible with most of the browsers in the market. The user can control day-to-day tasks for instance Tweets, Texting on WhatsApp, etc. The limitations are endless for automation in Selenium. Even the web pages where the content varies and is dependent on the user’s actions can be automated using Selenium.
The components of Selenium Architecture are as follows:
Various libraries such as Java, Python, and Java are supported by Selenium. The developers have created the language bindings that permit Selenium to support numerous languages. You can also visit the official website to know more about the Selenium libraries.
A browser is ideally a software that allows users to find and also view information on the internet. It interprets all the HTML tags in documents that are downloaded and format the data which is displayed as per the set referring to the standard of the style rules.
Every browser has its browser driver. It communicates with its browser without letting anyone know about the internal logic of the functionality of the browser. When a driver receives any command, then the same command will be executed on the corresponding browser and the same response will then go back in the form of a Hypertext Transfer protocol response.
So you now know the features and components of Selenium. Let us further understand what its advantages and disadvantages are!
