QTP Vs SELENIUM

QTP: -

Functional Testing Tool -QTP has the feature for storing screenshot of each and every page navigated during the execution. So it can be used as a proof for completion of testing, and also we can refer the screenshots of previous executions if there is any need to refer them. Test report can be automatically written to a customized report page which will ensure accuracy of the report and also it can improve look & feel of the report

Advantages of Using QTP

§User friendliness and less effort for script creation.

§Meets the needs of both technical and non-technical users.

§Advanced solution for functional test and regression test automation.

§Automation scripts are executed within specific interval of time using task scheduler/crone job.

§Many inbuilt functionalities by default and easy configuration.

§Excellent Object Identification process/mechanism.

§Easily integrated with test management tools like QC.

Disadvantages of QTP

In recent economic crisis, software companies are planning for cost reduction and efficient productivity. QTP is losing its market because of the following limitations:

§Runs only in Windows environments.

§Cannot test with all browser types and versions.

§Limited to smaller organizations/ testing teams.

§High licensing and add-inns costs.

§Slow in execution when compared with open source tools.

Selenium: -There are four variants of Selenium, which can be used in isolation or in combination to create complete automation suite for your web applications.

§Selenium IDE – Recording/Creating and enhancing scripts

§Selenium Remote Control (RC)– Executing scripts

§Selenium Web Driver (API) – Cross browser testing

§Selenium Grid – Cross platform testing

Advantages of Using Selenium:-

§Simple and powerful document object model (DOM) level testing, can be used for continuous integration with agile projects.

§Has great extensibility and flexibility, along with its tight integration with the browser unmatched by   available proprietary tools.

§Supports multiple browsers such as Internet Explorer, Fire fox, Safari or Opera on  Windows, Mac OS X and Linux.

§Wires Object Oriented Programming languages like JAVA, .NET, Ruby, Perl, PHP, etc.

§Provides the option of using wide range of IDEs such as Eclipse, Netbeans, Visual Studio etc depending on  the choice of development language.

Disadvantages of Selenium: -

§Supports only browser based application, not the windows application

§Does not support file uploads from local machine

§Provides only partial support for dialog boxes

§Being an open source, Selenium has no official technical support 

Comparison between Selenium and QTP is as follows:-

FEATURES	SELENIUM	QTP
Cost	Open source & Portable	Licensed and very expensive; Ten user license costs approx. 60L
Application support	Web Applications only	Client server applications only (like built in TCL/TK and PowerBuilder)
Support for web browsers	Supports IE, Firefox, Safari and Opera	Supports IE & Firefox only
Object Oriented Language support & Scalability	Supports Java, .Net, Perl, PHP, Python, and Ruby	Supports VB script only
Support for operating system/platforms	Supports Windows PC/MAC/UNIX Platforms	Supports Windows Platform only
Support for Test management tool integration	Not available. Need to track separately	TD/QC will be easily integrated
Test Development Environment	We can use wide range of IDEs like Eclipse, Netbeans, Visual Studio etc	Need Separate environment
UI object management & Storage	Managed using UI-Element user extension and properties A set of dynamically loaded libraries that is stored in the Java archive file.	Built-in object repository and easy handling
Support for Dialog Boxes	Supports partially	Supports all kinds of dialog boxes
Support for File upload (system)	Not available	Supports all kinds of File upload

Conclusion:-

· Using Selenium as the Functional Test Automation Tool, you can reduce the cost incurred for licensing using QTP.

· The efforts involved in scripting for Selenium increased by about 15 % than QTP in the initial stages. Once all the solutions are in place the efforts of automation using Selenium and QTP were almost the same.
