Use BeanShell PostProcessor in If controller using Jmeter - jmeter

I'm trying to create a file which contains a Regex variable.
I'm using BeanShell PostProcessor to create the file which add values from the vars.
I want to add it to If controller so it will add the value to the file only if a condition comes out as True.
My BeanShell code is:
artLink = vars.get("artLink");
// If you want to overwrite, then don't pass the second argument
f = new FileOutputStream("result3.csv", true);
p = new PrintStream(f);
this.interpreter.setOut(p);
print(artLink);
f.close();
When I take the BeanShell out of the If Controller, it creates a file, but when I put it back, no file is being created.
So I guess the problem is with the If condition.
My If condition is:
"${notFound}"=="AA"
The "notFound" is the regex var and "AA" is the default value.
So my question is if BeanShell PostProcessor can't be done under If controller, or is it my IF condition which makes the problem?

Beanshell Post Processor won't be executed if there are no other Samplers under the If Controller.
So the options are:
Switch from Beanshell Post Processor to Beanshell Sampler
Add another sampler which does nothing, i.e. Dummy Sampler as a child of the If Controller
See How to use BeanShell: JMeter's favorite built-in component guide for more information on Beanshell scripting in Apache JMeter and a kind of Beanshell cookbook.

I want to fail Beanshell sampler when my script is not conditions not satisfied

I am using Beanshell sampler with java code to compare the two files line by line. I want to fail the Beanshell sampler if comparison failed at any line. I see always my beanshell sampler is sucess in view results treee even the comparison failed or passed. So any one please give me a idea how to fail the sampler.
Note: I used Beanshell Assertion as well but its not worked.
View Results Tree Image
Beanshell Sampler with Beanshell Assertion
boolean differenceInFile = false;
SampleResult.setSuccessful(differenceInFile);
IsSuccess=differenceInFile;
line #2 and line #3 is what you need in your bean shell sampler to pass / fail depending on your file comparasion
Sample JMX File
It will show you as an xml, try to download it
There is SampleResult pre-defined variable which you can use for setting the sampler passed or failed, define response code, response message, response body, etc.
So something like:
if (there_are_differences) {
SampleResult.setSuccessful(false)
SampleResult.setResponseCode("500")
SampleResult.setResponseMessage("Files are different")
}
In the assertion you have AssertionResult for the same.
Also be aware that you should be using JSR223 Test Elements and Groovy language for scripting since JMeter 3.1 so it might be a good option for migration.

How to create a Java program in Beanshell PostProcessor in Jmeter to merge all the responses?

I have to send JSON requests based on the CSV test data. Suppose there are 90 records - which are basically the request bodies. I put the Thread in a loop to keep sending the request until the last one in the CSV.
Every time I get the response, I need to append them into a single CSV file. Now, since Jmeter Listener does not consolidate all the responses into CSV (I do not want it in xml), I want to know if I can write a Java snippet in BeanShell, capture all responses and write them to a CSV file.
You can use JSR223 Sampler with File.append adding text with , to append to CSV file
This will append to the end of the file.
File file = new File("out.txt")
file.append("hello\n")
If you want the "program"
Add JSR223 Listener to your Test Plan (since JMeter 3.1 it is recommended to use JSR223 Test Elements for scripting)
Put the following code into "Script" area
new File('myfile.csv') << prev.getResponseDataAsString() << System.getProperty('line.separator')
where prev stands for previous SampleResult class instance. Check out Top 8 JMeter Java Classes You Should Be Using with Groovy article for more information on JMeter API shorthands available for the JSR223 Test Elements.
A better option would be saving a response into a JMeter Variable using i.e. Regular Expression Extractor and writing it to a file via sample_variables property

How to pass response from one beanshell sampler to another beanshell sampler in same thread in Jmeter

I am making dme2 call to api from beanshell and i am getting response from it like {"stagedcustomerId":"165ce369-a9fb-4d42-b8f0-f119a6ae20eb"}
so now i want to pass only customer id value to another beanshell sampler for next api call as one of parameter in request body in same thread in jmeter.
Please suggest what can we do in this case. is there any way to do beanshell postprocessor?
You can use SampleResult shorthand in order to define the Beanshell Sampler response data like:
SampleResult.setResponseData("{\"stagedcustomerId\":\"165ce369-a9fb-4d42-b8f0-f119a6ae20eb\"}","UTF-8")
Once done you can add a JSON Extractor as a child of the Beanshell Sampler and configure it like:
That's it, now you will be able to access the extracted value as String id = vars.get("id"); in other Beanshell Sampler or as ${id} in any other test element.
Also be aware that starting from JMeter 3.1 it's highly recommended to use JSR223 Test Elements and Groovy language for scripting so consider refactoring your test on next available opportunity.

How to use variable "sampler" in JSR223 Sampler (JMeter)

I'm finding the way to use the variable sampler in JSR223 Sampler, JSR223 PreProcessor, JSR223 PostProcessor, and all other JSR223 script.
There are some other variables like vars, props, prev, SampleResult. I can use them easily.
For example:
vars: vars.get("VARIABLE_NAME"), vars.put("VARIABLE_NAME","VALUE"), ...
props: props.get, props.put, ...
prev: prev.getTime(), prev.isSuccessful(), prev.getLatency(), ...
SampleResult: SampleResult.getResponseCode(), SampleResult.getResponseMessage(), ...
But I don't know how to use variable sampler. Only thing I can do with this variable is:
sampler.sample(): It helps to returns the Name of current Sampler
So, could anyome please let me know there is any other way to use this variable?
Thanks in advance!
For JSR223 Sampler sampler variable stands for JSR223Sampler, see the JavaDoc for all available methods and fields.
When it comes to JSR223 Pre or Post Processor - in that case sampler variable stands for parent sampler class instance, for instance in case of HTTP Request it will be HTTPSamplerProxy, for JDBC Request - it will be JDBCSampler and so on.
You can check exact class using Groovy expression like:
log.info(sampler.getClass().getName())
You can check How to Use BeanShell: JMeter's Favorite Built-in Component guide for more information on pre-defined variables and their usage. It is applicable for Groovy as well.
sampler is a Sampler object. you can use whatever the methods available here, not only methods declared in Sampler class but also the methods in super classes/interfaces like TestElement.
For example:
sampler.sample() - returns sampler's name
sampler.setProperty() - set a property by specifying key, value
sampler.setThreadName() - set thread name for the sampler.

how can i pass dynamic values to url in jmeter

I have to give dynamic values to url which takes number of users and their age , which can be selected though web page. but I want to give it in Jmeter using BeanShell PostProcessor.
Help me in this,since I'm new to Jmeter.
This is the path:
/destinations/packages?airports%5B%5D=LGW&units%5B%5D=000577%3ADESTINATION&when=29-05-2016&until=&flexibility=true&flexibleDays=3&noOfAdults=2&noOfSeniors=0&noOfChildren=1&childrenAge=3&duration=7114&first=0&searchType=search&searchRequestType=ins&sp=true&multiSelect=true
from what I've got looks like you can use CSV Data Set Config.
Create .txt file with the data you want to feed your test with;
Place the above .txt file to the folder where your .jmx file lies;
In your Test plan: Under your request sampler - place CSV Data set Config;
Then if you need to use your dynamic values within one threadgroup => refer these data as ${quanity}, ${age} in you url.
If you need to pass these values across the threadgroups => add BeanShell Assertion
Then (in the other Tread group) refer those as ${__property(_quantity)},${__property(_age)}.
Hope, it helps.
First of all you need Beanshell PreProcessor, not Beanshell PostProcessor.
All this parameters are basically name/value pairs which can be defined via HTTPSamplerBase class. HTTPSamplerBase class instance is available to Beanshell PreProcessor as sampler pre-defined variable so if you add the following code into the Beanshell PreProcessor "Script" area
sampler.addEncodedArgument("airports[]","LGW");
sampler.addEncodedArgument("units[]","000577:DESTINATION");
sampler.addEncodedArgument("when","29-05-2016");
sampler.addEncodedArgument("until","");
sampler.addEncodedArgument("flexibility", "true");
sampler.addEncodedArgument("flexibleDays","3");
sampler.addEncodedArgument("noOfAdults","2");
//etc
Your HTTP request will be populated with the values, you set via Beanshell.
JMeter Variables can be accessed via vars shorthand which stands for JMeterVariables class instance.
String airport = vars.get("airport");
sampler.addEncodedArgument("airports[]", airport);
//etc
See How to Use BeanShell: JMeter's Favorite Built-in Component article for comprehensive information on how to use Beanshell Test Elements in Jmeter.
Remember that it is recommended to avoid scripting where possible so if there is another way of implementing your task - go for it.
