Is there a way to overwrite the http response headers returned in Jmeter? I'm testing a web service that returns JSON and when an invalid request is sent, the JSON response returned doesn't contain application/json (or any for that matter) in the response header. If I save the response to a file, I see the actual JSON returned, but looking at the response in a Results tree doesn't show a response. Unless there is a way to load the response from file and parse the error message from the file, I'm hoping to somehow overwrite the HTTP response header and force jmeter to treat the response as JSON.
Any suggestions are welcome!
Using a beanshell post processor, you can write some script that would force the value for the header, or write out to a file.
You can also add a listener that would write the results to file for you. Granted - this is less convenient for debugging then Tree View.
As it turns out JMeter does not support response header overloading. While the response isn't displayed in the Results tree, it is actually available to other assertions. I was able to still provide assertions to validate responses even though the response was missing from the GUI.

I'm looking for an alternative tool to Gatling and found Locust. I found it's powerful but I wonder how can I extract a Json value and then using that value in the Json payload of the next request (please note the Json payload is in different file). Like in Gatling we can use saveAs() and the value will be store in the session variable, then we can put that value in Json payload.
Thanks,
Hoang
Locust is pretty much just Python, using the requests http client, so look in to the requests documentation for more info.
Lets assume /login returns a session_id in the json response that we want to use in future requests. You would then do something like this in your task:
response = self.client.post("/login")
session_id = response.json()["session_id"]
self.client.post("/foo", json={"session_id": session_id})
When manually entering value in below parameters, it's working fine and showing a valid response.
Below post shows data when values are manually entered:
POST https://qatbagp523.unix.gsm1900.org/wcs/resources/store/11151/quoteHandler/syncQuote
POST data:
{
"opportunityId":"92456",
"quoteNumber":"54044"
}
[no cookies]
But same value captured from regular expression will not show valid response data
Below post data values captured from regular expression
POST https://qatbagp523.unix.gsm1900.org/wcs/resources/store/11151/quoteHandler/syncQuote
POST data:
{
"opportunityId":"92456",
"quoteNumber":"54044"
}
[no cookies]
Even same post data values but manually entered post data is showing valid response but regular expression captured post data is not showing valid response
I observed headers and other valuesm there is no change, could any please resolve how to get response and what could be the cause for this type of issues
Given you send the same requests you should be getting the same responses, if you have different responses - most probably you're sending different requests
Compare 2 requests using View Results Tree listener, they should be exactly the same in terms of request body, request headers, etc.
Check the variable which is stored by the Regular Expression Extractor using Debug Sampler, it might the case there are extra spaces, line breaks, etc.
Use a third-party external sniffer tool like Wireshark or Fiddler as View Results Tree listener doesn't always tell the full story
If you won't be able to figure out the root cause of the issue - consider saving all the request and response data for both Samplers and update your question with the XML file containing these details.
I'm a newbie in using Jmeter and searching for a solution solving the following problem: I have a suite that contains a set of atomic HTTP requests and the goal is to save response bodies into an xml file. Currently, I'm handling that with using "Save Responses to a file listener", but need to be able to save separately error and OK responses in different XML, based on response HTTP code and body string.
to illustrate the case with dummy code
if (HTTP response code == 200 OK && body does not contain "ERROR") then
save response to file (%path%\responsename_OK.xml
else
save response to file (%path%\responsename_ERROR.xml
My bad, Nikolay, I forgot you wanted it in xml format...
Well, the easiest way is to add 2 Simple Data Writers (SDW) to each HTTP Request where 1 SDW logs only errors and the other logs only successes.
The Pro's are
it's easy and once you set it up for 1 HTTP Request, you can simply copy it to every other HTTP Request
Each success or failure with be appended to the corresponding .xml file
You can define as much or as little detail as you want
The Con is you add 2 elements to each Request, thus increasing your test size twice as much as you would with a BeanShell Assertion. (if that's a concern for you.)
If you want a more detailed way, you could try a BeanShell Assertion scripted with XML Parsers and XPath Assertions like outlined here.
Use Response Assertion (in fact you will need 2: one for Response Code and another one for Response Body checking) in order to fail the request basing on these criteria
Use If Controller for setting a condition:
${JMeterThread.last_sample_ok} will be triggered if previous sampler is successful
!${JMeterThread.last_sample_ok} - will fire if previous sampler fails
N.B. you should have any Sampler under the If Controller so it could work.
I'm calling a REST request for authentication. And I need to get the session ID sending on response; in order to reuse that in my next request.
session id comes in Response header. When I use view result tree, this is not showing header parameters(response body has no data).
When googling I found a method using Regular expression Extractor method, but seems it works only when data in response body.
Nope, Regular expression extractor can search in headers also. You need to specify where to search.
See example,
This will search in headers and you can specify in main samples, sub samples also.
I am using JMeter to do load-testing. My test consists of a simple POST request. When I perform this request, the server, in its error logs, says No Payload Detected. I have verified that the server is receiving a Post request, and I have tried different texts in the Raw Post Body.
Next, to make sure it wasn't a problem with the server, I used a different Http Request program (Wiztools rest client) to send off a post with the same content. It works, and no No Payload Detected error is thrown.
My current theory is that both JMeter and the server do parsing. I know the server does, as it is looking for a small piece of data, and that JMeter's parsing ruins that small piece of data.
So, in conclusion, my question is "What parsing does JMeter do?".
I've looked for this answer, and the only thing I know that it does parse is ${VARNAME}.

Here is an screenshot of JMeter. This is the only request, with no other config elements:
You may also need to add an HTTP Header Manager as a child of HTTP Request to set some header like content-type:
First of all. In your question above, both in screenshot and in request text part of request has symbols < and > encoded and part - not. And you are using Content Encoding = UTF-8 in addition. Seems that in this situation request will be sent malformed.
You can add e.g. View Results Tree listener and check how the request is sent from jmeter.
You can try dedicated REST Sampler as well.
