Selenium is a free automated test package (open source) for web applications in different browsers and platforms. It is quite similar to HP Quick Test Pro (QTP now UFT) only that Selenium focuses on the automation of web-based applications. The tests performed with the Selenium tool are generally known as Selenium Testing.

Components of selenium testing
It has four types component of selenium
Selenium RC (remote control)
Before talking about the details of Selenium RC, I would like to take a step back and talk about the first tool in the Selenium project. Selenium Core was the first tool. But, Selenium Core touched an obstacle in terms of cross-domain testing due to the same origin policy. The same source policy prohibits the JavaScript code from accessing web elements hosted in a different domain compared to the origin of the JavaScript.
To overcome the same source policy problem, the testers needed to install local copies of Selenium Core (a JavaScript program) and the web server that contained the web application that was being tested to belong to the same domain. The permanent solution to this problem turned out to be Selenium RC. What does RC do then?
Selenium IDE (Integrated development environment)
In the way Selenium IDE is an addition to Firefox, which is used for fast and frequent execution of simple test cases. Test cases in IDE are created by recording the interactions that the user had with the web browser. These tests can be played several times.
The advantage of Selenium IDE is that the tests registered through the add-on can be exported in different programming languages such as: Java, Ruby, Python, etc. See the following screenshot of the Firefox IDE add-in.
Selenium grid
Selenium Grid was a part of Selenium v1 and was used in combination with RC to run tests on remote machines. In fact, with Grid, multiple test scripts can be run at the same time on several machines. Parallel execution is achieved with the help of the Hub-Node architecture. Hub controls test scripts that run on multiple browsers, operating systems and programming languages on multiple nodes.
Selenium Web Driver
Unlike IDE, Selenium Web Driver provides a programming interface to create and execute test cases. The test cases are written in such a way that the web elements in the web pages are identified and then actions are carried out in those elements.
Webdriver is an RC update because it is much faster. It's faster because it makes direct calls to the browser. RC on the other hand needs an RC server to interact with the web browser. Each browser has its own controller in which the application is executed.
Advantages of selenium
The first advantage is Selenium is a suite of tools that helps in automating only web applications. The Selenium IDE software is a Firefox plugin that allows testers to record their actions following a technological process that they need to test. Selenium Web Driver-is the successor to Selenium RC which sends commands directly to the browser and retrieves results.
Disadvantages of selenium
  • Supports only web based applications.
  • No IDE, so the script development won't be fast
  • Cannot access controls within the browser.
  • No default test report generation.
