Selenium Framework Explained – Everything you need to know


Software Development is a challenging and lengthy task. However, the critical part begins after building the software when developers need to test the software for bugs or defects that impact the functioning of the software.

There are two ways in which a software developer can detect bugs in the web application. The first process is testing cases manually. However, that is a lengthy process. Moreover, it is difficult to find all the bugs in the program manually. It results in a wastage of time and resources, and the companies have to incur extra costs.

The other prevalent process to test web applications is to use automated software. It saves time and cost for companies and also provides more accurate results as compared to manual testing. One of the most widely used automated software is Selenium Framework. Let us learn more about Selenium Framework and its characteristics.

What is the Selenium Framework?

Selenium is an automated software that tests web applications. The Selenium framework is an amalgamation of various selenium tools that automate the web applications testing process. It reduces the time of test cycles, saving money and resources.

In simple terms, Selenium is an open-source automated software framework that tests the functioning of Java, .Net, and AJAX web applications through various software that support javascript like Google Chrome, Firefox, Internet Explorer, Mozilla, Opera and SeaMonkey.

The Selenium Automated Framework is based on a script-less concept and requires minimum initial coding. It can be used on different operating systems such as Windows, Linux and Macintosh.

The Selenium Automation Framework also runs efficiently on mobiles. A distinct advantage of the Selenium Framework is that it contains several grids that simultaneously enable parallel testing of multiple web applications. Moreover, the Selenium Framework uses accelerators that make the entire process of testing web applications quick and efficient. The Selenium framework is flexible, which means that it can be integrated with other tools to produce the desired results.

The Selenium Framework Testing system runs tests that are written as HTML codes. The output is saved on a dashboard.

What are the key features and benefits of the Selenium Framework?

Here are some of the significant features and benefits of the Selenium Framework:

  1. Flexible and User-friendly:- One of the greatest advantages of the Selenium Framework is that it is open-sourced and user-friendly. This means that the users can download it as an extension on their system from the official website without any cost. Moreover, the Selenium Framework is flexible. You can install it on different operating systems such as Windows or Linux and different browsers also. It is also dynamic and can be integrated with other applications to test software.
  2. Generates HTML Reports:- Since Selenium Framework is automated software, it automatically generates extensive test results reports in HTML. The users receive this email report via mail. It helps to track and keep a record of all information. Through HTML reports, the Selenium testers can figure out and resolve the bugs in software.
  3. Multi-browser Function:- As already stated above, the Selenium Framework works on multiple browsers such as Google Chrome, Internet Explorer, Mozilla Firefox and more. You can also run the program on multiple browsers simultaneously.
  4. Does Not Require Server Installation:- While using the Selenium RC tool, engineers require a Selenium server to execute test scripts. However, to run the Selenium Framework on a remote machine using the Selenium WebDriver plugin, we do not need to install Selenium Framework on a server because the WebDriver serves as a direct link between the automation script and the browser.
  5. Tests Software Built Through Different Programming Languages:- While testing an application or software, the developers break it into multiple fragments called units which are run through testing unit frameworks. It is one of the most crucial components of software testing. The Selenium Framework supports various programming languages like Java, Python, Ruby, PHP and Scala. These languages help to build testing unit frameworks like TestNG.

Different Types of Selenium Framework Tools

Selenium Framework is a compilation of the following Selenium tools:

  1. Selenium (Integrated Development Environment) IDE:- This tool is a Firefox plugin that helps to generate Selenium tests. It allows the testers to keep a record of their workflow.
  2. Selenium RC:- This tool is a step ahead of the Selenium IDE. It allows the developers to write Selenium tests by using various programming languages such as Java, Python, Scala, Ruby and others. We require a Selenium server to use this tool.
  3. Selenium WebDriver:- To make Selenium Framework more automatic and flexible, the Selenium WebDriver was introduced as a successor to the Selenium RC tool. Since it directly sends the command to the browser, you do not need a Selenium server with WebDriver.
  4. Selenium Grid:- This tool acts like a proxy server that enables the Selenium Framework to run multiple tests across different browsers parallelly.

What is Selenium?

Selenium is a free and open-source test automation tool for validating web applications on a variety of browsers and platforms. Selenium Test Scripts may be written in a variety of computer languages, including Java, C#, Python, and others. Selenium Testing is the term for testing performed with the Selenium toolset. The software is a collection of tools that includes the Integrated Development Environment (IDE), Selenium Remote Control (RC), WebDriver, and Selenium Grid, among others. Each piece of software is tailored to a company's specific QA testing requirements.

What are the limitations of Selenium testing?

Because Selenium is an open-source technology, there is no specialised tech support to help users with their problems. To test desktop and mobile apps, Selenium must be combined with third-party tools such as Appium and TestNG. It also offers limited picture testing capabilities. Selenium lacks a built-in reporting and test management feature, necessitating integration with third-party tools such as TestNG or JUnit, among others, to ease test reporting and management. It may also necessitate programming language experience, as Selenium WebDriver assumes the user has some programming knowledge. Finally, security becomes a setback with this Grid because there are several Cloud-based labs in the market that provide a higher level of security.

What are the components of Selenium?

Selenium IDE (Integrated Development Environment), WebDriver, RC, and Grid make up the framework. Selenium Integrated Development Environment (Selenium IDE) is a recording and playback tool. It's a Firefox add-on. WebDriver and RC provide APIs for a wide range of languages, including Java,.NET, PHP, and others. Webdriver and RC are compatible with the majority of browsers. Grid is the last component. Grid allows you to distribute tests over numerous workstations so that they may be performed in parallel, reducing the amount of time it takes to execute browser test suites.
