<h2 id="h-what-is-selenium"><span id="What_is_Selenium">What is Selenium?</span></h2>



<p>Selenium is also an open-source framework for web automation. It provides a bunch of tools and libraries that can be used across various platforms and supports a lot of programming languages such as Java, Python, ASP .Net, C#, Ruby, JavaScript, etc. Selenium can be called the most popular automation framework among web automation testers nowadays. It is commonly used for functional testing of web applications that can be used to script interactions with web elements, simulate user actions, and verify the expected behaviors of web pages.</p>



<h3 id="h-how-does-selenium-work"><span id="How_does_Selenium_worknbsp">How does Selenium work?&nbsp;</span></h3>



<p>The initial functioning of the Selenium framework is based on the interactions with web browsers via its component called Selenium Webdriver. This communicates with the respective browsers using the browser’s native automation support. The test scripts which can be written using a preferred programming language guide the WebDriver to simulate user interactions such as clicks, form submissions, and text inputs. The WebDriver translates those commands into browser-specific actions. Selenium has been one of the most popular choices for automation testers because of its flexibility, cross-browser compatibility, and capability of integration with many programming languages. Especially, its WebDriver component enables direct communication with web browsers during testing. However, there are some differences in each when it comes to <strong>Selenium WebDriver vs WebDriverIO</strong>.</p>



<h3 id="h-why-should-i-use-selenium"><span id="Why_should_I_use_Seleniumnbsp">Why should I use Selenium?&nbsp;</span></h3>



<p>Most of the automation testers choose Selenium due to various reasons. First, Selenium is a powerful open-source <a href="https://website.testsigma.com/blog/test-automation-frameworks/" target="_blank" rel="noreferrer noopener">automation framework</a> for web automation that provides cross-browser compatibility and support for a lot of programming languages.
