2.       Navigate to folder in which JAR file is saved.

3.       Run the following command  java -jar driverJAR.jar where driverJAR.jar is the name of JAR file



Double clicking on a batch file 


1.       Create a new text file in the same location as the JAR file.

2.       Rename the file as test.bat, thus creating a batch file.

3.       Add following content in the bat file

SSO with SAML login scenario in JMeter

SAML(Security Assertion Markup Language) is increasingly being used to perform single sign-on(SSO) operations. As WikiPedia puts it, SAML is an XML-based open standard data format for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. With the rise in use of SAML in web applications, we may need to handle this in JMeter. This step-by-step tutorial shows SAML JMeter scenario to perform login operation. First request from JMeter is a GET request to fetch Login page. We need to fetch two values ‘SAMLRequest’ and ‘RelayState’ from the Login page response data. We can do this by using  Regular Expression Extractor . These two values need to be sent in POST request to service provider. Refer below image to see how to do this. We will get an HTML login page as a response to the request sent in 1st step. We need to fetch values of some hidden elements to pass it in the next request. We can do this b

VBScript Code - Function to convert CSV file into excel and viceversa in QTP using VBScript

We at times are required to convert excel files into csv to read as flat files and sometime require to convert a csv file into excel file to use excel features on the data.   Below function shows how to convert an csv file into excel file and vice versa. We can also convert to other formats based on constants Here constant value 23 is used to create a csv file and constant -4143 to save a file as xls file. Once the destination file is created, we can delete the source file as shown below.  In case of any issue in understanding the code, please add in comment section Call func_ConversionCSVExcel("E:\Test.csv", "E:\Test_converted.xls", "csvtoexcel") Public Function func_ConversionCSVExcel(strSrcFile, strDestFile, Conversion) on error resume next Set objExcel = CreateObject("Excel.application") set objExcelBook = objExcel.Workbooks.Open(strSrcFile) objExcel.application.visible=false objExcel.application.displayalerts=

Reading data from text file in SoapUI using groovy script

How to read data from text file in SoapUI. SoapUI Pro has some advance feature which is not in SaopUI as data fetching from external sources so in SoapUI we use Groovy script for that.
