Selenium

Selenium is a popular open source Web UI (User Interface) automation testing framework. It was created in 2004 as an internal tool at Thought Works by Jason Huggins. Selenium Online Training is a browser automation tool that works with a variety of browsers, frameworks, and programming languages.

Before we get started with this tutorial, let's review some of the core concepts related to application automation testing.

With the increasing demand for efficient software products, every software developer must conduct a set of tests prior to releasing the final product. Test engineers work hard to find flaws or glitches in software before it is released, but shipped software still has flaws. Also with the best manual testing processes in place, there's always the risk that the final software product will have a flaw or will fail to meet the end user's requirements. Automation testing is the most reliable, efficient, and comprehensive way to improve the effectiveness, performance, and scope of your Software Testing.

Selenium can run on a variety of platforms, including Windows, Linux, Solaris, and Macintosh. Furthermore, it facilitates mobile operating systems such as iOS, Windows Mobile, and Android.

The most critical part of the Selenium Tool Suite is Selenium WebDriver. WebDriver API is incorporated with the new update "Selenium 2.0," which offers a simplified and more succinct programming interface.

Selenium WebDriver was first released with Selenium v2.0. Only IDE, RC, and Grid were included in the first edition of Selenium, dubbed Selenium v1. RC, however, has been discontinued and migrated to the legacy bundle with the introduction of Selenium v3.

Test scripts can be written in any of the compatible programming languages and move straight in most modern browsers with WebDriver. WebDriver supports the following languages: C#, Java, Perl, PHP, Python, and Ruby.

The following are some of Selenium WebDriver's most significant features:

Selenium WebDriver works with a wide variety of web browsers, including Firefox, Chrome, Internet Explorer, Opera, and several others. It also allows some unusual or uncommon browsers, such as HTMLUnit.

WebDriver also follows the majority of commonly used programming languages, including Java, C#, JavaScript, PHP, Ruby, Pearl, and Python. As a result, the user can choose any approved programming language depending on his or her proficiency and begin writing test scripts.

WebDriver is quicker than the other Selenium Training in Chennai Suite tools in terms of performance. It does not, unlike RC, demand an intermediary server to interact with the browser; instead, the tool directly communicates with the browser.
