I am using jmeter tool for websocket testing. I need to create multiple orders with multiple users and for that i need to set up csv data set. How can i use it in websocket sampler? As i can see that the request is sent in "Request Data" section but how should i give the variable names there and how would it read through csv?
There might be a bug in the "websocket sampler" plugin you are using. Try out WebSocket Samplers by Peter Doornbosch, current version (JMeterWebSocketSamplers-0.12.jar) doesn't seem to be having problems with parameterizing via JMeter Functions and/or Variables
You can install the plugin using JMeter Plugins Manager
I don't know which Websocket plugin you're using, but see this for best solution:

If you follow the one we advise , then just add a CSV Data Set config to your plan filling required fields:
Pay attention to Variable Names (example here myData1).
You can then use it through:
${myData1}

How can I handle data from ":/some/api/link" while I am recording using JMeter it works and when I try it again it shows "null" message in 'View results tree'.
In the majority of cases you won't be able to record and replay you test as modern applications and web APIs normally use dynamic parameters for authentication and security purposes. So most probably your Test Plan should look as follows:
1st request
Post Processor (in case of REST API it will be JSON Extractor, in case of SOAP API it will be XPath Extractor) to extract any dynamic parameters and save them into JMeter Variables
2nd request where you should replace hard-coded recorded values with the variables defined in the previous step
The easiest way to detect the dynamic parameters is recording your test 2 times and compare the generated requests, you will need to correlate parameters which differ.
See API Testing With JMeter and the JSON Extractor for more details.

I have local Header manger for each request. I also have Global one. [Please look at the image] I want to remove local Header manager for all requests.
I tried it by creating a preprocessor and writing "sampler.getHeaderManager().removeHeaderNamed("HTTP Header manager");" inside it. But, It's not working. Because of this, It cannot authenticate credentials.
I also tried "sampler.getHeaderManager().remove(0)". This didn't work too. remove(1) ignores the global header manager.
Here is my suggestion. Care must be taken care while following the below steps. I follow this trick to replace dynamic values.
Take a backup of your JMeter script.
Open the script in the notepad++.
Find the Header Manager tags. It goes something like this
<hashTree><HeaderManager guiclass="HeaderPanel" testclass="HeaderManager" testname="HTTP Header Manager" enabled="true"><collectionProp name="HeaderManager.headers"/></HeaderManager><hashTree/>
If you have many Header Manager Name and its name unique, you can use regular expression in notepad++.
Reg ex syntax in notepad++
<hashTree><HeaderManager guiclass="HeaderPanel" testclass="HeaderManager" testname="(.+)" enabled="true"><collectionProp name="HeaderManager.headers"/>
</HeaderManager><hashTree/>
Replace it with empty value using Find and Replace.
While replacing, please take care of <hashtree></hashtree> tags, any conflicts will result in corruption in the script. Use Test Plan Check Tool plugin to validate your test plan. Please visit this link to know more https://jmeter-plugins.org/wiki/TestPlanCheckTool/
Save it and open in JMeter.

Give your "global" header manager a different name
Run your test via Taurus tool. Taurus naturally supports JMeter tests execution and adds some extra features on top, for instance Modifications for Existing Scripts. Assuming your test is called test.jmx the relevant Taurus config file will be as simple as:
---
execution:
scenario:
script: test.jmx
modifications:
disable: HTTP Header Manager
If you save it as i.e. test.yml and execute Taurus as:
bzt test.yml -gui
a JMeter instance will launch and open your script with Header Manager elements disabled.
See Navigating your First Steps Using Taurus article for more information on the approach.
Currently it is not possible to fully remove test elements programmatically, you can only remove individual headers. Going forward you might want to untick Capture HTTP Headers box under HTTP(S) Test Script Recorder in order to avoid this situation:
I'm writing functional test and having difficulty mocking http:request-config with oauth2. It failed at requesting for token. I tried moving the config to a separate file and create a different config in src/test/resources and include only the test config when testing. Now it complains about "name must be unique" - how do I get around this?
Be sure that your getConfigFiles() override does not include the configuration file that contains the original . This means it will need to be in a separate file from the one containing the flow you are testing.
Another method is to use a mock HTTP server such as sham-http.
In order to test Mule application you can use MUnit:
http://developer.mulesoft.com/docs/display/current/MUnit
It will allow you to mock message processors.
Now, config elements are top level elements. Those can not be mock.
I would suggest you take a look to documentation to see if the tool fit your needs.

I have created a Restful Service which accepts input xml and outputs response xml. Before giving output xml it calls Web Service and gets the xml from it. I do some modifications to the xml and output it.
The client reports that when they do load testing, sometimes the response comes properly and sometimes does not from RESTful Service.
How can I do load testing with JMeter and find the loophole in it. This happens for multiple calls.
2 great references for jmeter are:
- http://blog.milamberspace.net/ if you talk french
- http://theworkaholic.blogspot.fr/ if not
But you should definitely start by reading :
- http://jmeter.apache.org/usermanual/index.html
Then ask questions on jmeter user list if you are stuck.

First create new test and save test scenario with JMeter Proxy (records user clicks in a browser).
Then use the recorded components to compose your actual test.
Don't forget to use JMeter Plugins (invaluable).
How to pass struts form parameters in Jmeter. I got in formation by using Regular Expression Extractor we can solve it but, i am not getting any information how?
I think the best way is NOT to create the requests yourself ( if that's what your doing ), but instead use jmeter as a proxy to record your web app flow. The proxy recording session will take take of boring head parameteres that, in my opinion, are too tedious to add by hand. You can find how to set up the jmeter proxy mode here and here. You can't miss it.
good luck!
