Beanshell Script Examples (Random string & logging to external file)

Beanshell script examples for generating random string & logging data to external file

Add the BeanShell Post Processor to the required request

Copy the below code to the Script window

Modify the script as per the requirement (assign the parameters to the variables)

Generate Random string:

// Generates a random string import java.util.Random; chars = "0123456789-ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz"; int string_length = 32; randomstring ="";     for (int i=0; i<string_length; i++) {         Random randomGenerator = new Random();       int randomInt = randomGenerator.nextInt(chars.length());         randomstring += chars.substring(randomInt,randomInt+1);                    } vars.put("uniqueStr",randomstring);

Logging JMeter data to external file:

//Assign to the variables randomstr1 = vars.get("uniqueStr"); dtime11 = vars.get("dtime1"); rnd1 = vars.get("rnd"); regpass1 = vars.get("regpass"); //logs the information to jmeter.log log.info(randomstr1); log.info(dtime11); log.info(rnd1); log.info(regpass1); //Creating an file object and writing to a csv file FileWriter fstream = new FileWriter("C:\\apache-jmeter-2.9\\beanshell_log\\detail_log.csv",true); BufferedWriter out = new BufferedWriter(fstream); out.write(randomstr1+dtime11+rnd1+","+regpass1+"\n"); out.close();

Executing Linux commands from Windows Command Prompt using Putty/Plink

Download PUTTY : http://the.earth.li/~sgtatham/putty/latest/x86/putty-0.63-installer.exe

1. Install PuTTY
2. Set the environment variables path for PuTTY: {install dir}/PuTTY
• My Computer --> Right Click --> Properties --> Advanced System Settings --> Environment Variables
3. Auto login command:
• plink.exe -ssh <username>@<ip address> -pw <password>
• plink.exe -ssh root@xxx.xxx.xx.xx -pw password
4. Auto login and invoke a terminal command: 
• plink.exe -ssh <username>@<ip address> -pw <password> "<terminal command>"
• plink.exe -ssh root@xxx.xxx.xx.xx -pw password "nmon -f -s10 -c 360"

JMeter - Creating date time string using javaScript & Beanshell

For MM/DD/YYYY date string use the below functions

1. using javaScript function:
${__javaScript(var d=new Date(); var date=d.getDate(); var
month=d.getMonth()+1; $DATE=(month<10?"0"+month:month) + "/" +
(date<10?"0"+date:date) + "/" + d.getFullYear();,DATE)}

Thus __javaScript() allows multiple lines of code as long as they are
separated by ";"

2. or using BeanShell
${__BeanShell(new java.text.SimpleDateFormat("MM/dd/yyyy").format(new
Date()))}


For MM/DD/YYYY date time string use the below functions

1. or using BeanShell
${__BeanShell(new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new
Date()))}

JMeter Random String [A-Z,a-z,0-9]

Random String

Generate a random string using [A-Z,a-z,0-9]


For generating a random string length of 5 then use the below function

Name: randomstr5
${__RandomString(5,ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789,)}

For generating a random string length of 10 then use the below function

Name: randomstr10
${__RandomString(10,ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789,)}

BeanShell script for Date Time format yyyyMMdd HH:mm:ss.SSS

Add the below code in User Parameters to generate the date time format like 

yyyyMMdd HH:mm:ss.SSS


Name: DateTime
Variable: ${__BeanShell(new java.text.SimpleDateFormat("yyyyMMdd HH:mm:ss.SSS").format(new Date()))}
