As we all know that there exists lots of web based dynamic applications in the market that are of common use and get a huge traffic on their interface. These types of applications are responsible to perform an automated test for their correctness and proper working. Automation testing is done to ensure the quality and performance of a product or service.
Here with the help of this blog I would like to introduce you with about Selenium tool that is used for automation testing. Although I shall try to cover all necessary details in this blog but the complete practical knowledge of automation testing using selenium tool will be achieved through some dedicated training. I can suggest you an institute that is QACampus located in Fremont , California where you can get a quality practical education for selenium testing.
An introduction to Selenium Tool in detail
Selenium is an open source automated tool used to automate test for web based application. It supports different web browsers such as Opera, Firefox, Chrome, Internet Explorer, Safari, etc. This tool comprises of different software tools which are :
Selenium IDE ( Integrated Development Environment)
Selenium Web Driver
Selenium RC (Remote Control)
Selenium Grid
Selenium IDE :- Among the four selenium tools this framework is the simple one that is easiest to learn. This tool is a Firefox plug-in that can easily be installed and provides interface for the development of automated tests. The tool is a prototyping tool used to build test scripts. This tool can be used to perform only simple tests but in need of advanced tests, Selenium Web Driver or RC have to be used.
Features :-
Easy to install and use.
No programming knowledge except DOM and HTML are required.
Tests can be exported to be used by Web Driver ad RC.
It has built in results reporting module and help.
It provide extensions support.
Selenium Web Driver :- This tool is more effective than Selenium RC and IDE in many facets. It employs stable and modern approach to automate a web browser. It does not depends on Java Script to perform automation hence it controls web browser by communicating directly with it. The tool supports languages such as Java, Python, C#, Perl, Ruby, PHP etc.
Features :-
Installation is simpler than RC.
Communicates directly with browser.
More realistic browser interaction.
It does not require separate component as required by RC.
Fast test execution than RC and IDE.
Selenium RC (Remote Control) :- This is the first automation testing tool for web that facilitates testers to use programming language as per their choice. The tool support languages such as C#, Python, Perl, Ruby, Java, PHP etc.
Features :-
It supports cross browser and cross platforms.
Conditional operations and looping can be performed.
It supports data driven testing.
Fast execution than Selenium IDE.
Is having a complete API.
Selenium Grid :- This tool is used to perform parallel tests execution across multiple browsers and machines. It is used with Selenium RC for automating a test.
Features :-
Enables concurrent tests execution on multiple browsers.
It employs hub - node concepts with hub as main source of Selenium commands and node as multiple machines connected with it.
It saves time to run test suits.
After getting this detailed information about Selenium automation tool we an say that, this is an advantageous tool in terms of flexibility and cost. Using this we can run multiple tests at a single time unlike QTP in which test can only be executed sequentially.
This is all about Selenium automation testing. If you are also required to automate your web test than you can go for a well defined training in Selenium Testing. The training will help you learn advanced strategies of using selenium for web automation test. Also it will help you grow in your present testing job after developing your skills.
