Selenium - The Main Components of Selenium Test Automation Suite

by John Smith Digital Marketing Expert In this era of Agile software development and short deadlines, the more time that can be reduced in any stage of the software development life-cycle, the better. Testing is a vital but time consuming task if done manually. Many of the repetitive testing routines can be automated by testing scripts and tools like Selenium.

Testing professionals can benefit from corporate certification training on Selenium testing. Many premier institutes offer Selenium testing training in Noida.

Automated Web Testing with Selenium

Selenium is an open source test automation tool for web applications. As a large number of current projects are being deployed in the web, there is a need for testing the application for performance on different platforms and different web browsers.

Automated testing with Selenium provides a versatile testing solution that has multiple resources to automate testing tasks, from simple record and playback to testing on multiple machines on multiple platforms through a remote server.

Main Components of Selenium

Selenium was developed by Jason Huggins at Thought Works. He developed a JavaScript Library that can record and control interactions with a web page and then rerun the steps to repeat the tests. This JavaScript library became the core of the Selenium RC and Selenium IDE.

Selenium IDE

Selenium IDE s the basic component that can record and playback user interaction with web pages. Selenium IDE is available as an add-on to Firefox and it allows users to record, edit and debug tests. These recorded steps are exported as script files that can later be used to automatically run the tests.

Scripts are recorded in Selenese, a test scripting language This scripting language provides commands for simulating user interactions like button click, selecting an option or clocking in a link.
Selenium also provides a comprehensive set of APIs for writing scripts in other programming languages. Currently there are Client APIs available for Java, Ruby, C# and Python.

Selenium Remote Control (Selenium RC)

Selenium RC is a server based test automation tool. It makes it possible for tests to be written in different programming languages and automated tests to be run on different browsers. Selenium client drivers are now available for many development platforms like Ruby, Java, .Net, Perl and Python.

Selenium WebDriver

Selenium WebDriver is the successor to Selenium RC. WebDriver does not need a special server to interact with the browsers. Instead, it initiates and controls a new instance of the browser. Also, instead of relying on JavaScript for test automation like the Selenium RC, WebDriver uses the particular browser's native automation support. This allows a deeper and fuller integration with the browser. Also, in cases where just browser interaction is not enough, WebDriver's approach also enables access to OS level interaction.

Selenium Grid

Selenium Grid extends the Selenium RC server solution to enable test runs on large networks, on multiple platforms. One server acts as the hub in a Selenium Grid. Tests contact the hub for browser instances and the hub provides access to browser instances running on different nodes in the network.

Selenium Grid also allows parallel test runs. Multiple tests can be executed on different machines at the same time. This can help speed up the testing process for large tests, by breaking down the test into small units that can be run on different machines in parallel. In addition, the Grid enables the tests to be executed on different platforms, thus ultimately ensuring the program works uniformly well in different environments.

Selenium Automated Testing - A Suite of Tools for Flexibility and Scalability

By offering a set of tools that ranges from the simple record and playback to writing test automation in different languages and enabling testing on different machines on different browsers, this open source tool offers a lot of power and functionality.
Professional training in Selenium testing is a good way to add value to the job profile of software professionals. Selenium testing training in Delhi/NCR or Noida is an option in many reputed institutes in this region. Professionals can choose from a range of Selenium Testing Courses.
