Basics of Selenium – Know Its Features and Components For The Best Understanding!

Introduction:

Selenium is a powerful tool for controlling web browsers through software. It works in all browsers, runs on all major operating systems, and is scripted in various languages ​​such as Python, Java, and C#. Work in Python. Selenium has four main components: Selenium IDE, Selenium RC, Selenium Web Driver and Selenium GRID. Taking the Selenium training in Chennai will give the best options for learning all these tools by one stop solution.


Components of Selenium:

Selenium has been in the industry for a long time and is used by automation testers worldwide.

Let's look at the four major components of selenium.


  • Selenium IDE

  • Selenium RC

  • Selenium Web Driver

  • Selenium GRID


Selenium IDE:

Selenium IDE (Integrated Development Environment) is the core tool in the Selenium suite. It is an Integrated Development Environment (IDE) for Selenium Testing. It is implemented as a Firefox extension and Chrome extension. You can record, edit and debug functional tests. Formerly known as Selenium Recorder. Selenium-IDE was originally written by Shinya Kasaya and contributed to the Selenium project in 2006. Selenium IDE has been actively maintained in 2018.


Scripts are auto-recorded and can be edited manually, so they are auto-complete and get you working quickly. Scripts are written in Selenese, a special test scripting language for Selenium. Selenese provides commands to perform actions in the browser (clicking links and selecting options) and to retrieve data from retrieved pages.


Selenium RC ( Remote Control ):

Selenium Remote Control (RC) is a server written in Java that accepts browser commands over HTTP. RC allows writing automated tests for a web application in any programming language, enabling better integration of Selenium into existing unit testing frameworks. To make writing tests easier, the Selenium project now provides client drivers for PHP, Python, Ruby, .NET, Perl, and Java. A Selenium RC server instance is required to run the html test case. That is, each parallel execution must have a different port. However, for Java/PHP test cases, only one Selenium RC instance needs to be running continuously.


Selenium Web Driver:

Selenium WebDriver is the successor of Selenium RC. Selenium WebDriver accepts commands (sent in Selenium or via the client API) and sends them to a browser. This is implemented through browser-specific browser drivers that send commands to the browser and retrieve results. Most browser drivers launch and open a browser application (such as Firefox, Google Chrome, Internet Explorer, Safari, or Microsoft Edge). There is also an HtmlUnit browser driver that emulates a browser using a headless HtmlUnit browser.


Instead, WebDriver directly launches and controls a browser instance. However, Selenium Grid can be used with WebDriver to run tests on remote systems (see below). Wherever possible, WebDriver uses native operating system level functionality instead of browser-based JavaScript commands to drive the browser. This gets around issues with subtle differences between native commands and JavaScript, including security restrictions.


Selenium Grid:

Selenium Grid is a server that allows your tests to use web browser instances running on remote machines. In Selenium Grid, servers act as hubs. The test connects to the hub to access the browser instance. The hub has a list of servers that provide access to browser instances (WebDriver nodes) and you can use these instances in your tests.


Selenium Grid allows tests to run in parallel on multiple machines and manage different browser versions and browser settings centrally (instead of each individual test). External browser agencies are available for distributing load tests in multiple devices and for testing in browsers performed on various operating systems or operating systems. The second is especially useful in cases where not all browsers are used for testing.


Features Of Selenium:

  • Open Source and Portable: Selenium is an open source web test framework.

  • Combination of tool and DSL: Selenium is a combination of tools and DSL (specific domain language) for different types of tests.

  • Easier to understand and implement: Selenium commands are categorized into different classes which make it easier to understand and implement.

  • Reduce test execution time: Selenium supports parallel test execution, which reduces the time required for parallel test execution.

  • Lesser resources required: Selenium requires less resources as compared to competitors like UFT, RFT, etc. 

  • Supports Multiple Programming Languages: C#, Java, Python, PHP, Ruby, Perl, Javascript

  • Supports Multiple Operating Systems: Google Chrome, Mozilla Firefox, Internet Explorer, Edge, Opera, Safari, etc.

  • Supports Multiple Browsers: Android, iOS, Windows, Linux, Mac and Solaris. 

  • Parallel Test Execution: It also supports parallel test execution, which saves time and improves testing efficiency such as testing the frameworks. This can be done with the help of the professionals who had the Dot Net Training in Chennai.


Conclusion:

Selenium test tools have advantages and disadvantages compared to other automation test tools. In conclusion, the three main features of Selenium and its various components make Selenium one of the best test automation tools.
