What exactly is selenium?
When it comes to cross-browser testing, Selenium is a set of technologies that is frequently utilized in the testing community. Selenium can only be used in browsers and cannot automate desktop apps. It is regarded as one of the most popular tool suites for web application automation testing since it supports a variety of popular web browsers, making it quite powerful. FITA Academy offers the best Selenium Training in Chennai to enhance your skills in testing with career guidance.
What is Selenium WebDriver, and how does it work?
Selenium WebDriver is a web framework for performing cross-browser testing. This programme is used to test web-based applications to ensure that they work as expected.
To write test scripts, Selenium WebDriver lets you choose a programming language. As previously stated, it is an improvement to Selenium RC in that it overcomes a few shortcomings. Although Selenium WebDriver is unable to handle window components, this limitation can be bypassed by using tools such as Sikuli, Auto IT, and others.

Architecture of the Selenium WebDriver Framework
The four key components of the WebDriver Architecture are:
- Selenium Client library
- JSON wire protocol over HTTP
- Browser Drivers
- Browsers
Client Libraries/Language Bindings for Selenium
Selenium supports a variety of libraries, including Ruby, Python, Java, and others, thanks to language bindings created by Selenium developers to ensure language compatibility. Use the Python Bindings, for example, if you wish to use the browser driver in Python. From Selenium’s official website, you can download all of the supported language bindings of your choosing.
JSON Wire Protocol (JSON Wire Protocol)
The acronym JSON stands for JavaScript Object Notation. It is an open standard that provides a web-based transport method for data transfer between clients and servers. It supports numerous data structures such as arrays and objects, making it easy to read and write JSON data.
JSON is a REST (Representational State Transfer) API that allows HTTP servers to exchange data. Learn more about the REST API and how to use it to access Selenium.
Drivers for web browsers
Selenium provides drivers for each browser, and the browser driver communicates with the relevant browser by creating a secure connection, without revealing the core logic of browser capabilities. These browser drivers are also particular to the test case automation language, such as C#, Python, or Java.
You can choose your preferred browser driver based on your linguistic requirements. On BrowserStack, for example, you can set up the Selenium Web driver for Python.
Advantages Of Selenium WebDriver:
- It is one of the most widely used Open-Source tools for testing web-based applications and is simple to use. You can also run cross-browser compatibility tests using it.
- Multiple operating systems are supported, including Windows, Mac OS X, Linux, Unix, and others.
- It works with a variety of languages, including Python, Java, Perl, Ruby, and others.
- Modern browsers such as Chrome, Firefox, Opera, Safari, and Internet Explorer are supported.
- When compared to other tools, Selenium WebDriver completes test script execution faster.
- API (Application Programming Interface) is more concise than Selenium RC’s.
- It may also be used with iPhoneDriver, HtmlUnitDriver, and AndroidDriver.
Conclusion:
Selenium Webdriver is simple to use and is one of the most extensively used Open-Source tools for testing web-based applications. It can also be used to do cross-browser compatibility testing.
