i need to write a Assertion error, assertion failure and Assertion failure message(example data below in the pic) to a csv file. What is the best way to do this? Is there a possibility to create a JSR223 Sampler to read assertion messages from all http requests at once and save that to csv file? Built-in saving to file does not meet requirements.
Picture
JSR223 Sampler will only have access to the previous sampler result, I would recommend using JSR223 Listener and the following code:
vars.put('failureMessage', prev.getAssertionResults().find { assertionResult -> assertionResult.isFailure() }.getFailureMessage())
the code will extract the failure message from the first assertion
then you need to declare Sample Variables property in user.properties file like:
sample_variables=failureMessage
and finally the variable can be written to a file using Flexible File Writer listener (this guy can be installed using JMeter Plugins Manager)

I am using Jsr223 sampler and performing a login activity.
Using log.info in Jsr223 sampler, I am able to print a cookie value in JMeter log viewer.
I want to capture that value again from logviewer and pass it as an header manager input to another request.
log.info(something) will print the value of something to JMeter log file
vars.put('someVariable', something) will save something into someVariable so you will be able to refer it as ${someVariable} in the HTTP Header Manager (or where required)

I would like to use Jmeter to generate HTTP TimeStampRequests "application/timestamp-query" as presented in the standard RFC3161.
Currently I'm using Java program to do it but I would like to improve it by using Jmeter functionalities.
Is it possible to do it ?
If you want to use JMeter's HTTP Request samplers you can:
Compile your code into .jar file
Put the .jar into JMeter Classpath
Use the function from the .jar file to generate the request body from the JSR223 PreProcessor
Set the request body to the value generated in the step 3

While doing Testing I need to taken the token from Oath API and use it in another subsequent API's which is successfully done. But when HTML report is generated through CLI the Oath API's Response time and Throughput is also calculated, is there a way we can ignore that request ?
Add to requests JSR223 PostProcessor below them which will ignore request/response
prev.setIgnore()
prev - (SampleResult) - gives access to the previous SampleResult
Call this method to tell JMeter to ignore this SampleResult by Listeners
There are following options:
Add JSR223 PostProcessor as a child of the Sampler(s) you need to exclude from Listeners/test results/whatever and put the following code into "Script" area:
prev.setIgnore()
Use FilterResults Tool (available via JMeter Plugins project, can be installed using JMeter Plugins Manager), it allows excluding sample results basing on strings or regular expressions or time offsets or both
JMeter .jtl result files are basically CSV files, you can use your favourite text editor or tool like MS Excel to remove the result entries you're not interested in
I have a requirement to download zip file from server through JMeter to test the peroformance but for me the downloaded files are shown in x-filler, i need to have the zip file downladed.
Please help me here
Thanks in Advance
Simulating file download event using JMeter is as simple as sending HTTP GET request using HTTP Request sampler.
If you need to save the response somewhere for later reuse or analysis add Save Response to a file listener as a child of the request which performs the download. Check out Performance Testing: Upload and Download Scenarios with Apache JMeter article for comprehensive explanation.
Be aware that storing responses will cause huge disk IO overhead during the load test so I would recommend ticking Save response as MD5 hash box under "Advanced" tab of the HTTP Request sampler and use MD5Hex Assertion to compare the MD5 checksum of the response with some reference value.
To download any file, you need to extract it using Regular Expression Extractor.
Add the Regular Express Extractor to the request where you want to download and configure the fields as shown below. Use (?s)(^.*) as the expression to extract everything.
Add the Save Responses to a File sampler and configure the fields as shown below.
Execute the test plan. In the JMETER_HOME\bin\, you can see the zip file. Extract the zip file and validate.
The easiest way is to use your own code to download the file. The options are BeanShell Postprocessor or JSR223 Postprocesor.
I extracted file name from response header Content-Disposition, save it to varible, and the use variable for filename. Additional variable was defined on Test level, holding folder name where to save files.
I have been assigned with a task to capture the XML data inside a response body of a sampler in Jmeter. I've tried many ways to save the response data but there is no luck.is there any way to save the Response data in xml format using Jmeter? looking for a positive reply.
Add the next 2 lines to user.properties file (located in JMeter's "bin" folder)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
Run your JMeter test in command-line non-GUI mode like:
jmeter -n -t test.jmx -l result.jtl
You will be able to see response data for each sampler in result.jtl file.
See Configuring JMeter user manual chapter for more information on JMeter property files and properties
If you need to store the response data of one single sampler only, add JSR223 PostProcessor as a child of this sampler and put the following code into "Script" area:
new File('myFile.xml') << prev.getResponseDataAsString()
Once you execute JMeter test you should see myFile.xml in JMeter's "bin" folder, it will contain response data. Check out Groovy Is the New Black guide to learn about Groovy scripting in JMeter.
