I want print my json response in jmeter. I used beanshell but it shows error. Below is the line to print json object extracted in "data":
log.info("========"+${data});
Don't ever inline JMeter Functions or Variables into scripts, they may resolve into something which will cause compilation/interpretation failure, use code-based equivalents instead or pass functions/variables via "Parameters" section.
Exhibit A: using vars shorthand
log.info("========" + vars.get("data"));
Exhibit B: using "Parameters" section
Using Beanshell isn't the best scripting option, consider migrating to JSR223 Elements and Groovy language as Beanshell has known performance problems. Moreover, Groovy has built-in JSON support See Apache Groovy - Why and How You Should Use It for details.
And finally your ${data} variable might not be defined (i.e. your extractor fails), in this case you will get interpretation failure on attempt to refer it as ${data}, double check its value using Debug Sampler and View Results Tree listener combination.

Please tell me why the code in comments (both /*something*/ and //something) is executed using JSR223 Sampler & BeanShell sampler?
For example, I have:
and in the next JSR223 Sampler I have:
and the result is:
and the question is: why this code: "/${__setProperty(checkProperty, 50)};/" is executed regardless of that it is in comment and it is in wrong condition?
JMeter Functions are being executed in the place where they're found, no matter where it is, in Sampler label, comments section, sampler body, etc.
Actually inlining JMeter Functions and/or Variables into JSR223 scripts is not the best idea as
it might conflict with Groovy's string interpolation syntax
the function or variable might resolve into something causing script compilation failure or logic error
and last but not the least Groovy will cache the first occurrence and use it for subsequent iterations
So if you need to set a property - use props.put() function like
props.put('foo', 'bar')
And finally I'm not sure that using props.clear() is a good idea because there are some pre-defined JMeter properties (you can check yourself using Debug Sampler and View Results Tree listener combination) and it might result into unexpected behaviour if a test element will be relying on that property existence and/or value
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.

I am trying to set value in beanshell inside "CANCEL ORDER" sampler and then use in sampler request body.
Trying
vars.put("orders",Arrays.toString(orderList.toArray()));
and accessing in json request body using ${orders} and its not passing value.
{
"orderIds": ${orders},
"tonce": "${tonce}"
}
POST data:
{
"orderIds": ${orders},
Your "not passing value" doesn't tell anything to us, if your Beanshell script doesn't work as expected first of all you need to check jmeter.log file for any suspicious entries, if your script fails somehow you will be able to see the error message in the log.
It worth checking your orderList variable value using Debug Sampler or printing it to the aforementioned jmeter.log file using log.info() shorthand
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting as:
Groovy has built-in JSON support
Groovy performs much better comparing to Beanshell
I am using a jmeter JSON extractor for a JSON that looks like this
{"type":"rpc","tid":7,"action":"SecurityManager","method":"getAuthenticationKey","result":"-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAydpVbheWPx4ZMbxJ8yCm\ndcP2EaRZD2R4PUmuFhdDdvpxT\/so00\/22orFQMgw8hrgEZ07ISzarOlclchm7DtF\nzxUzjGon1d5OJ2\/61niT+bAyuykn7y63\/BEtGS3KsR9ez3Ds+JR04Tca\/ajUYAIo\nrtAdCuvQuWkk4ZmZWywa7n899KOndL8S3G0R9Bex5XwfXJoE2BC6Ww75gwkzANFX\nIqkTYeepIMai3B8H31VIW2aJXURbjgN4yrk4sOy5a5JqnPEeCPKJR3nCrZDZGG06\ncoq0swW8oegNI9SFsiIqpDQ6Fi4WqqH5EMNu6FrkF3HAqwwyGljnogGNdnkwajiu\nCQIDAQAB\n-----END PUBLIC KEY-----\n"}
I am trying to use that value (for example just show it)
log.info("${key}")
, but I get the error
o.a.j.p.j.s.JSR223Sampler: Problem in JSR223 script JSR223 Sampler, message: javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script26.groovy: 8: expecting anything but ''\n''; got it anyway # line 8, column 39.
log.info("-----BEGIN PUBLIC KEY-----
Is there something i am not doing right ?
You should never use ${} in Groovy script in JMeter.
Instead do this:
log.info("Got key:{}", vars["key"]);
Provided your variable is named key
And this is how you would configure JSON Extractor:
Given you use JSR223 Test Elements already you don't need the JSON Extractor, the PEM key can be extracted and printed in one shot via JSR223 PostProcessor
Add JSR223 PostProcessor as a child of the request which returns the above JSON
Put the following code into "Script" area:
vars.put('key', new groovy.json.JsonSlurper().parse(prev.getResponseData()).result)
log.info(vars.get('key'))
Enjoy the printed variable in Log Viewer window
Of course you will be able to access it as ${key} in the other Test Elements

Apache Groovy - Why and How You Should Use It
Going forward please avoid using JMeter functions and/or variables in Groovy scripts as they conflict with Groovy GString Templates, may be resolved into something which cause compilation or runtime failure and non-compatible with Groovy caching of compiled scripts feature negatively impacting JMeter performance.
I am trying to use the variables captured in the Debug Sampler in Jmeter and then convert those variables into some other value. And then use it somewhere in the script.
I have added a BeanShell Sampler along with the Debug Sampler and tried to get the variables displayed in the Debug Sampler.
Below is the piece of code I have written in Jmeter.
Jmeter
Is my approach correct? Am completely new to Jmeter and have little Java knowledge. So please help me here and let me know how can I convert or use a variable through a Custom code in Jmeter.
It is almost correct, you have a couple of syntax errors (missing closing bracket and undefined SomeCharacter)
Also it is better to use JSR223 Elements and Groovy language rather than Beanshell, as Groovy performance is much better and it is more Java-compliant, see Groovy Is the New Black article for detailed explanation.
Final code should look something like:
def myVariable = vars.get("Corr_ContextN")
if (myVariable.equals("002056653")) {
vars.put("myvariable1", "SomeCharacter")
}
Keep in mind that you are not changing original Corr_ContextN, you are creating new variable myvariable1. Also in order to see new variable you need to move the Debug Sampler after the Beanshell Sampler
Your got the concept but your code has the following errors:
imports are wrong and useless. You only need to import Classes for unbound variables, ie the ones that are advertised in the component.
There's a missing ')' in the if clause
SomeCharacter is not defined
And you should avoid Beanshell and favor JSR223 Test Element with Groovy as per those recommandations:

Note that there is also a __groovy function for your use case.
