- This is the twentieth video of JMeter Tutorial series which covers Introduction to BeanShell script and its variables
Learning:
What is BeanShell?
• scripting language developed in java
• it can dynamically execute standard java syntax
• scripting features- loose type (variables are declared without any type) , commands etc
Why BeanShell scripting required in JMeter?
Many a times, you might need additional scripting to customize the script in your own way, even though general functionalities of JMeter cover many needs of a performance test. In such cases Beanshell scripting comes into picture.
In JMeter, BeanShell script can be executed with the help of:
• BeanShell sampler
• BeanShell pre processor
• BeanShell post porocessor
BeanShell sampler - it has provided predefined list of variables which we can use in our script
vars.put("link", "www.google.com"); - to set the value of a variable
var x =vars.get("link"); - to get the value of a variable
log.info("value of x is "+ x); - to print inside the logs
ctx.getThread().getThreadName(); - to get thread name

Hi very nice way of narration. Recently started working on the tool extensively. I'm using JMeter for MQTT Testing. Have a question can I get the Latency value captured and write it to log using Beanshell? Trying to capture latency value in MQTT subscriber sampler. Kindly update me on this.
Very well explain mam also easy to understand and implement.
I m facing the issue even after passing the if statement in beanshell for request 2 its not stopping the execution. And execute the second request after failing the first request.
Please help
Thanks in advance
Awesome..... Can u pls make a video regarding integer variable in beanshell scripting and how to pass to next requests or use in IF controller.
I am facing issue with this. In my case i have jdbc preprocessor from where I'm pulling a value which can either be null or valid value. Then i pass this value to beanshell preprocessor where i am doing this handling using if. But when i am sending null value to http request it is not working. But if value is value other than null then it wroks
Nice one. Can you please post all your codes (used in this video) in the Description? Thanks.
do you have any video about passing okta token from one thread to another thread?
Great JMeter videos but I really wished you could have used light theme in Jmeter instead of a dark theme.
Yeah! very sorry about that
Quality Assurance Lab Thanks for the reply! Wish you good luck. And waiting for more learning from you 😊
@@iMadeThisThat Thank you, please let me know if you want video on any specific topic.
good video. but please have all your notes types out already before taping the video. it could reduce your videos time in 1/2 and keep us from losing attention. it just drags on when we see you typing it out.
Hi There, thank you for your videos! it is really helpful. I have one question, in previous video, var is thread scope. How about ctx, is it thread scope or test plan scope? look forward to hearing from you. thanks!
Glad to know my video is helpful to you!
Both var and ctx are thread scope. var is an instance of the org.apache.jmeter.threads.JMeterVariables class.And, ctx is an instance of org.apache.jmeter.threads.JMeterContext class.
How can we capture and customise scripts of "Secured passwords" and "captcha" through beanshell?
Can you make a video for Taurus and JMeter ?
the video was really very informative..just one question:Suppose my 1st thread is login and 5th thread is ABC ..I want ABC to be run only if login is successful....Can you please tell what comment we will use to do that.
Please reply to this question, and the above video was great
Hi Mam, Your videos are really helpful. Please can you tell me how can we store the comma separated elements in an array in a csv file with column name and row values. For ex: "options": [10,11,12,13,14]. The csv output should have 'options' as the column header and 10,11,12,13,14 in the rows below the header.

Good videos would have been better if theme was white as difficult see the cmd in Bean Shell
Hi i have one doubt, i am passing different type of variables through csv but i am not able get the values in request..can you please help me on that. Thank you
Very good videos. I have 1 issue. I am getting 20 response from 1 request and need to run a chain request 1-1 for these 20 responses. Any idea?
Hi, you can capture 20 response as variables using Correlation. Further, to run a chain request 1-1, use the variables where you have captured 20 response.
To know about correlation, please refer - ua-cam.com/video/gOGXMa08K3s/v-deo.html
Thanks for the reply. I am already using correlation. But not getting how to iterate them 1-1. Ex. After hitting a request i am getting 20 cities. Now in next HTTP request, I need to pass city 1-1 to check whether. Please suggest.
Hi @@sanjaygarg6688, Let's say that using correlation you received 20 cities as city_1, city_2.......city_20 . After this, follow the below steps:
Step 1: Add a Logic Controller -> Loop Controller , with loop count as 20
Step 2: Under Loop Controller, add Config Element -> Counter . Provide Starting Value -1, Maximum Value - 20, Increment - 1, Exported Variable Name - count . This configuration will store the value from 1 to 20 in the variable "count" every time Loop controller will run (here 20 times)
Step 3: Under Loop Controller, add HTTP Sampler and name it as city_${count}
Hope this helps, let me know for further query!
Thanks a lot. Just one thing, Is there any way to count the responses at run time if don't know how many cities will get.
i used below steps but every time it picks same request. I am getting IDs as a response and passing those ids to take further response. To achieve this, first i have used JSON extractor and used the values in variable. Now i have added loop controller and added counter, added function ${__counter(FALSE,)} in HTTP sampler. Please suggest where is an issue.
I keep getting ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method when i tried to execute Beanshell pre-processor .. any help will be much appreciated.
Thanks,

Hi Mam, I have 3 HTTP request, I have to pass 2 HTTP request based on condition on HTTPRequest 1 else I have to send HTTP Request 3. Kindly let me know on how to pass this HTTP Request
Add If controller and provide your condition. Add HTTP Request 2 under the same If controller. By doing this , HTTP Request 2 will be executed only when condition is true. If the condition is false HTTP Request 2 won't be executed.
Same process you can repeat for HTTP Request 3 as well
"jmeter bin is not recognized as internal or external command error" i am getting

" i have used this one
Typo in the command, try this org.apache.jmeter.engine.StandardJMeterEngine.stopThread(Thread.currentThread().getName());
