Selenium is a vital tool for controlling a web browser through a program. It is functional with all browsers, runs on all leading operating systems, and its scripts are written in various languages, including Java, Python, C#, and others. We will be working with Python. In this blog, we will discuss What are the key components of Selenium. To build your skills in Selenium, join Selenium Training in Coimbatore, where you’ll be trained by industry experts using case studies and real-world experiences. Selenium comprises four primary components:
- Selenium IDE
- Selenium RC
- Selenium Web driver
- Selenium GRID
Selenium IDE
Selenium IDE (Integrated Development Environment) is primarily a Firefox plugin. It is one of the most straightforward frameworks in the Selenium Suite. It enables us to record and playback scripts. To construct more advanced and robust test cases with Selenium IDE, you must need Selenium RC or Selenium WebDriver.
In Selenium IDE, test case execution is very slow, and the report-generating process for test cases is poor compared to other components. It does not support parallel or remote test case execution.
Some of the features of Selenium IDE-
- The Selenium IDE can record, debug, and edit functional tests.
- The programs in Selenium IDE are written in Selenese, a scripting language in Selenium.
- Selenium commands allow us to execute actions such as clicking a button or link, accepting input in an edit box, collecting text from a web element, and so on. Enroll in Selenium Training In Madurai and have hands-on experience working on live projects.
Selenium RC
Selenium RC, often known as Selenium 1, was the primary Selenium project long before the WebDriver merger gave rise to Selenium 2. Its automation is primarily based on JavaScript. It supports Ruby, PHP, Python, Perl, C#, Java, and Javascript. It is compatible with practically every browser available.
Some other features of Selenium RC-
- It is based on JavaScript. It does not have a record/playback feature.
- It is created on a client/server architecture, meaning you must manually start the server anytime you wish to run the test cases/scripts.
- It allows parallel test case execution and remote execution using Selenium Grid. To learn more about selenium testing, join Selenium Training In Hyderabad and become an expert.
Selenium WebDriver
A browser automation framework receives commands and outputs them to a browser. It is implemented through a browser-specific driver. It interacts with and controls the browser directly. Selenium WebDriver allows various programming languages, including Java, C#, PHP, Python, Perl, Ruby, and Javascript.
Some of the features of Selenium WebDriver-
- Automation tests can be written in various programming languages, including Java, C#, Python, and JavaScript.
- Selenium webdriver works with Chrome, Firefox, Safari, and Internet Explorer browsers.
- Selenium webdriver supports multiple platforms, including Windows, Mac, Linux, and Android.
- The HTMLUnit Driver can be used to achieve headless execution.
- The Selenium webdriver does not require a server to begin testing and instead connects directly with the browser.
- The Selenium webdriver is free and open-source.
Selenium Grid
Selenium Grid is a tool that is utilised in conjunction with Selenium RC. It is used to execute parallel tests on several PCs against various browsers. This means performing many tests simultaneously against different machines running different browsers and OS systems. You can also refer to this article on Selenium Grid to gain a more comprehensive understanding of the principles.
So far, we’ve only discussed the Selenium Components. This concludes the article. I hope you understand the principles and find them helpful in expanding your knowledge.
