Volume 3, No. 12, December 2012Journal of Global Research in Computer ScienceRESEARCH PAPERAvailable Online at www.jgrcs.infoSTUDY AND ANALYSIS OF AUTOMATION TESTING TECHNIQUESVishawjyoti*and Sachin SharmaDeptt of Computer Applications, Manav Rachna International : Testing is a very important activity in Software Development Process. It is to examine & modify source code. Effective Testingproduces high quality software. This Paper deals with a significant and vital issue of Software Testing. Testing can be conducted manually aswell as Automated. These Techniques have their own advantages & disadvantages. The Objective of this paper is to perform Automation Testingusing Software Testing Tool “Selenium”. With this web testing tool, test cases are automatically recorded in background while tester is enteringthe data in a web application screen.Keywords: Software Testing, Manual Testing, Automation testing, Selenium.INTRODUCTIONThe ultimate goal of software development is to producehigh quality software. Superior quality software hascharacteristics like low cost, reliable and user satisfactory.Testing is the process of executing a program with theintention of finding errors. This is a crucial & essentialactivity to discover all the errors early software developmentprocess. Emphatic & fruitful testing reduces the system cost.Software development houses recruit testing & qualityassurance personnel for performing testing activity.Test means program’s response to ever possible input. Aprogram should test for every valid & invalid input. Testingactivity can be conducted in to two ways: Manual testing &automation testing. Any type of software testing type can beexecuted both manually as well using an automation tool.Manual testing[5] is in which the testing activity isperformed by testing persons. Manual testing requires atester to perform manual test operations on the test softwarewithout the help of Test automation. Manual Testing is aprocess where in a tester often follows a written test planthat leads them through a set of important test cases. A testcase in software testing is a set of conditions written forparticular applications & tester run all these conditions toensure the correct functionality of the software applications.Manual testing is a laborious activity that requires the testerto possess a certain set of qualities; to be patient, observant,speculative, creative, innovative, open-minded, resourceful,opinionated, and skilful. In order to fully test that all therequirements of an application are met, there must be at leasttwo test cases for each requirement: one positive test andone negative test. Manual testing helps discover defectsrelated to the usability testing and GUI testing area. Anynew application must be manually tested before its testingcan be automated. Manual testing requires more effort, butis necessary to check automation feasibility. Manual testingdoes not require the knowledge of any testing tool.Automation Testing [6] is running test cases where manualintervention is not required to run each one. It uses special JGRCS 2010, All Rights Reservedsoftware to write & execute test cases to compare the actualoutcome with the predicted outcome. Once tests have beenautomated, they can be run quickly and repeatedly.Automated software testing is the best way to increase theeffectiveness, efficiency and coverage of software testing.Automation testing requires considerable amount ofinvestment for buying the software & compatible hardwareresources. Automation testing does what manual testingdoes not. Automation testing improves the accuracy & itsaves the time of the tester & organization’s money.Automation testing is best suited in the environment wherethe requirements are frequently changing & huge amount ofregression testing is required to be performed. Automationtesting is best suited in the environment where there arecritical test cases that are to be executed repeatedly. Itincreases the quality of testing structure & reduces the futuremaintenance cost. Various benefits of Automation testingare fast run of test case. Reusable test cases are made &these test cases are reliable, comprehensive &Programmable.The main difference between Manual testing & Automatedtesting is that Automation testing is best suited for theenvironment where the Repetitive work is more (e.g.,running regression tests, re-entering the same test data,and checking against coding standards). Also, manualtesting is best suited for the environment where therequirement changes continuously.INTRODUCTION TO SELENIUMSelenium[1] is a portable software testing used forAutomation testing It is a framework comprises of manytools used for testing web applications. Selenium provides arecord/playback tool for authoring tests without learning atest scripting language (Selenium IDE). It has a testdomain-specific language (Selenese) to write test cases in anumber of popular programming languages, including C#,Java, Groovy, Perl, PHP, Python and Ruby. All these testcases written can then be run against most modern webbrowsers. Selenium can run on any operating systemplatforms like Windows, Linux, and Macintosh etc. It isopen source software that can be down loaded from the36

Selenium was originally developed byJason Huggins, who was later joined by other programmersand testers at thought works.Selenium is a suite of tools for web automation testing.Selenium Suite includes following components: SeleniumIDE, Selenium Core, Selenium 1 (known as Selenium RC orRemote Control), Selenium 2 (known as Selenium Webdriver), Selenium-GridSELENIUM IDESelenium IDE is an integrated development environmentfor Selenium scripts. It is implemented as a Firefoxextension, and allows you to record, edit, and debug tests. Itwas previously known as Selenium Recorder. Selenium IDEis not only recording tool: it is a complete IDE. SeleniumIDE (Integrated Development Environment) works similarto commercial tools like QTP, Silk Test and Test Partneretc.In this paper our focus is to perform automation testing of aweb application using automation testing tool “SeleniumIDE”.STEPS FOR IMPLEMENTATION OF TEST CASESUSING SELENIUMProblem analysis:It is the process of gathering information to discover thebasis of positives & negatives of a proposed system. Forexample let us consider a problem to develop a website foruser registration & login. For this we have designed awebsite with the name DEMO. Here we have to test the webpage of a registration form of a website DEMO.The snapshot for Demo isFigure 2: Screen of registration pageWriting test cases: Test case is a document that includes aprocedure to perform testing. A test case includes a set oftest inputs, execution conditions, and expected outputdeveloped for a particular objective, e.g. to check aparticular program path or to verify that the specific inputwill meet with the desired output. There is no prescribedformat for writing a test case. , but a test case must includeinput, expected behavior, expected output. We have asample test case for first name field of registration page ofDEMO website.Figure 1: Main screen of website DEMO JGRCS 2010, All Rights Reserved37

Once activating recording mode,then what so ever data is entered in the web page willautomatically recorded in the selenium. For example whenvalue of Last Name is entered in the web page, thecommand corresponding to that is recorded on the seleniumIDE with command “type” target “name LastName” andvalue “garg”. Same value entered on web page.Figure 5: Screen for entering the value of field E-Mail & corresponding record in selenium.(iii) When value of E-mail is entered in the web page, thecommand corresponding to that is recorded on the seleniumIDE with command “type” target “name email” and value“ravi20007@ymail.com”.
