Please guide me whether is there any way to get the response data from jmeter to robotframework? I have integrated robotframework with jmeter and my use case is to do the data base validation using robotframework for that i want to get the unique id which i recieved in jmeter responce data.Due to some use case i cannot perform Database validation in jmeter itself.
I Dont see any keyword in the documentation,
https://kowalpy.github.io/Robot-Framework-JMeter-Library/JMeterLib.html
I don't think the plugin offers such functionality so the most straightforward way is writing your unique id into a file, depending on how you're getting the ID you can:
Use Save Responses to a file listener - it stores the whole response into a separate file
Use Sample Variables property - it adds specified JMeter Variable(s) values as a separate column(s) in the .jtl results file
Use Flexible File Writer listener where you have the full freedom to choose regarding what, where and how to store
Once done you can read the file using OperatingSystem library and do whatever you need with this ID

I have a scenario where one of the test REST API returns a transaction_Id, this transaction Id I need to pass in my next request(API Request), also upload the file as well. This upload file has name format like ${transaction_Id}_1_1_bkg.raw,without correct format backend server may not be able to analyze the data.
Since I have to run a load test, these transaction Ids will generate at run time and the same I have to change the file name and upload it as well.
Did any one had face this challenge before in Jmeter to change the file name at run time and upload it, if yes, what was the solution.
Thanks,
Akshat
You could copy the file to a new one with the desired name using JSR223 PreProcessor like
org.apache.commons.io.FileUtils.copyFile(new File('template_bkg.raw'), new File(vars.get('transaction_Id') + '_1_1_bkg.raw'))
where vars stands for JMeterVariables class instance, see the JavaDoc for more information on all existing functions and Top 8 JMeter Java Classes You Should Be Using with Groovy article to learn more about JMeter API shorthands available for the JSR223 Test Elements.
Once upload is finished you can delete the file using JSR223 PostProcessor
I'm not able to save response in PDF file generated from the APIs. I am using Jmeter for load testing and by the help of Jmeter I am calling the APIs.
In a Jmeter script I have 150 APIs. It's hard to go through all APIs to check the output. Is there any way to save the data generated by the APIs?
To save response from API you have to add Save Response to a file listener:
Right click on your API request.
Add -> Listener -> Save Response to a file.
Setup Variable Name containing saved file name.
At this step you may enable "Add Timestamp" setting, then date will be included in file suffix following format yyyyMMdd-HHmm_

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.
We have tried everything could someone please help us for the solution
I am sending a Get Request and getting this response {"UserID":"123456","SecurityApp":"123456"}
I want to save "UserID" content to a variable and also "SecurityApp" content to a variable and then use it in multiple POST request content
You have to use Regular Expression Extractor component of JMETER...
You will get both the UserID and SecurityApp using Regx Extractor.
and you can use those variables in subsequent requests...
There is a test element designed for extraction of data from JSON structures - JSON Path Extractor. It's available via JMeter Plugins - a set of custom extensions which make working with JMeter (and especially reporting) much more easier.
See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for installation and usage instructions.
For particular your case detailed steps will be:
Download Extras with Libs Set bundle to your JMeter installation root and unpack it.
Restart JMeter if it is running - plugins are not being picked up dynamically
Add a JSON Path Extractor as a child of the request which produces that UserID/SecurityApp response
Configure it as follows:
Variable Name: anything meaningful (i.e. UserID)
JSON Path: $.UserID
Repeat step 4 but this time provide $.SecurityApp as JSONPath and SecurityApp as a Variable Name.
After Post Processor's execution you will be able to refer extracted values as ${UserID} and ${SecurityApp} wherever required in current Thread Group.
I am using Jmeter(2.3.2) to create script for one of my application with a scenario which has flow for 4 to 5 pages. I have recorded the script using HTTP Proxy Server. The scripts has been generated successfully under Thread Group >> Recording Controller.
After running the scripts (Threads- 1, Ramp Up period - 1, Loop Count - 1 ), below are the observations I noted in View Results Tree:
The Result Tree view shows all as Checked(Green) - OK
The Sample result for all screens shows Error Count as 0 - OK
But in the response tab when I try to view the results by using 'Render Html' response data - the response data shows the same response for all the requests.
I am getting the response data of the first request for all the other requests.
I am not sure, whether the Jmeter script generated is functional or not? What is the cause for getting the same response data for all the requests?
Please, can anyone let me know what may the issue?
I bet that the same page you're observing is a kind of login page or dashboard which is accessible by unauthenticated user.
First of all make sure that you have HTTP Cookie Manager added to your test plan. It represents browser cookies and deals with user sessions and cookie-based authentication.
If it doesn't resolve your issue the problem is bigger and you will need to do some extra stuff. Modern web applications use multiple mechanisms of current state of things storing and managing, security enhancements and so on. From JMeter's point of view it results in dynamic mandatory parameters. The process of these dynamic parameters extraction from previous request and adding them to next request is called "correlation". So you need to do the following:
Detect which parameters being sent by a recorded script are dynamic. The easiest way is to record the same scenario several times and inspect request bodies to see what is being static and what changes.
Once you figure out which parameters are "interesting" you need to locate them in the first response body/headers/etc.
As soon as you have identified what necessary parameters are and where they live you need to use one of JMeter's PostProcessors to extract required values from previous response and save them to JMeter Variables
Once you have a JMeter Variable it can be used wherever required.
Depending on response data type the most commonly used JMeter's Post Processors which provide correlation capabilities are:
Regular Expression Extractor - the most commonly used test element which covers >90% of needs.
XPath Extractor - better to use against XML data i.e. for testing SOAP Web Services.
CSS/JQuery Extractor - when you need to fetch something from complex HTML where Regular Expression Extractor is useless.
So for putting everything together loog for "jmeter correlation" in your favorite search engine or see ASP.NET Login Testing with JMeter guide.
First JMeter 2.3.2 is WAY TOO OLD (10 years old), upgrade to JMETER 2.11.
Second, Jmeter cannot guess that the response if KO if the returned code is 200, so you need to add Response Assertion that will check for some text you expect in the page.
