while executing the API's using jmeter tool in the response i get some value as '1K\/vyEh'.
while storing this value in the variable it is observed that the backslash does not get stored in the variable resulting in saving the value as '1K/vyEh'
I need guidance of how to save the value as is in the variable
There are too many "unknowns" in your question so unfortunately it is not possible to provide a comprehensive answer without seeing:
at least partial (better full) response
and the way you're storing the value into a JMeter Variable
Here is a quick demo that in theory it is possible:
The demo assumes:
Dummy Sampler
JSR223 PostProcessor
Groovy language and regular expressions

I tried to pass a string from csv file to ${__base64Encode()} function but in result my API request is getting failed. When I checked my jmeter logs then in that I found that base64Encode function is unable to encode the string because it is too long and limit is 65535. So, is there any way by which I can increase the string limit to encode my string or is there other way because I need to pass that string to initially encode the data to make my script work.
Please find the attached screenshot for the error in mentioned link and let me know if there is any solution to resolve this issue.
Don't inline JMeter Functions or Variables in Groovy scripts, as per JSR223 Sampler documentation:
The JSR223 test elements have a feature (compilation) that can significantly increase performance. To benefit from this feature:
Use Script files instead of inlining them. This will make JMeter compile them if this feature is available on ScriptEngine and cache them.
Or Use Script Text and check Cache compiled script if available property.
When using this feature, ensure your script code does not use JMeter variables or JMeter function calls directly in script code as caching would only cache first replacement. Instead use script parameters.
Amend your code to look like:
vars.put('token', vars.get('token1').bytes.encodeBase64().toString())
and the error should go away
More information on Groovy scripting in JMeter: Apache Groovy: What Is Groovy Used For?
Alternatively just use ${__base64Encode(${token1},token)} function where required, but not in the JSR223 Test Element script
I'm trying to set a variable as a parameter value in a Backend Listener. I tried to add the variable as
${"testname"}
and also as
$["testname"]
but both options didn't work. JMeter consider them as a string and not as a variable. Any ideas how I can do that ?
The correct syntax for JMeter Variables is ${variable_name_here} so you need to change it to ${testname} and it should start working as expected.
If there will still be problems make sure that the variable is defined and has its respective value, it can be done using Debug Sampler and View Results Tree listener combination
P.S. Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting instead of Beanshell (and in fact any other languages) so while your script is relatively small maybe it's a good time for migration.
Can I replace a file content with dynamic content even if the file has special characters.
This is what I get when I try to do that.
and this is how my file looks like
[{"someName": "M`o\c\k","someNumber": "${randomNumber}"}]
and I have a variable configured for ${randomNumber}.
Please check if the below can met your requirement.
Random Variable Config:-
Dummy sampler for the json
JSR223 Post processor to put the dummy response in a variable
Used the variable in HTTP. This is just for demo. Probably, in your case it will be websocket.
Output
Also, groovy provide json support. Below you can check a similar solution based on groovy. Where it is mentioned to escape special character for json.
Jmeter Groovy how can I replace this string with {
Hope this helps.
I was able to solve my scenario by adding a json library to my JMeter, JSON.Simple. I added the jar to my jmeter classpath. Then I was able to a BeanShell PreProcessor.
The Json simple object will not escape the special characters and its much easier to manipulate. So that was great for my use case.
I have to ignore dynamic property value while cmpmarison. Can you please suggest how to do so.
Currently I have used as
(\d+)
And Pattern matching Rule as "Contains"
Can anyone please help on same

Given your current setup, if the response will contain any number - your assertion will pass, otherwise it will fail. You can use Perl5-style regular expressions to handle dynamic response parts and static strings for doing the checks. See How to Use JMeter Assertions in Three Easy Steps article for more information.
The other approach is extracting the dynamic parts using Regular Expression Extractor, converting them into JMeter Variables and using these variables in the Response Assertion. Regular Expression Extractor is executed before the assertion so this way you will be able to work it around in a more "transparent" way.
Looking to utilize jmeter for some automated testing but facing a problem. preliminary to my tests I want to run a query on my DB and then store the result in a text file.
I thought I'd do it via a JDBC request as such:
Then immediately after I want to do some post-processing that writes the result to our file:
I've tried, too, putting the paramater passed to vars.get in quotation marks, but I get no such luck. Jmeter does write a file, but that file is empty, and if I run the query independently, it does return results.
Does anybody know how to get this desired behavior?
If you look into jmeter.log file you should see a Beanshell Related error.
This is due to "Result Variable Name" being an ArrayList, not String, hence
You need to use vars.getObject() method instead of vars.get();
Ensure you quote the variable name
Remove the ";" at end of SQL Query
You need to iterate the ArrayList somehow or serialize it to file.
If result set is large it's better to consider doing it via JSR223 Sampler using "groovy" as a language as Beanshell has some performance limitations. See Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For! guide for benchmarking results and instructions on how to setup groovy scripting engine support.
To write the output to a file , see :
Append data into a file using Apache Commons I/O
If you decide to use Groovy it will be even easier :
