I had created a access token via first api call that i want to use in all other api call, it works for next call but it fails for third api call.
I am using Regular expression extractor, where i have created a variable named token, it passes in second api call in request header , but for third api call it is not taking it (it takes second api's response in the request)
This is due to JMeter Scoping Rules, if you have the Regular Expression Extractor at the same level as all Samplers - it will be applied to all Samplers, therefore when your Login request gets executed - your token variable gets overwritten with the Login sampler response.
If you want to extract the data only from the Login Token sampler - you need to make the Regular Expression Extractor a child of the Login Token sampler

I am using HTTP request sampler for API performance testing. My APIs might return a response containing the skiptoken
If response contains the skiptoken, I need to call the API again using the skip token and capture the performance metrics. I required calling the API until there are no skiptoken available in the response.
Please let me know how I can implement this in JMeter
You can add a Post-Processor, for example JSON Extractor, which will extract the skpitoken into a JMeter Variable from the API response.
If the variable is defined you can add If Controller and send another request to the API with the variable from the previous step.
Something like this:
You have to use any of the Post processor according to your API response content. e.g, Json extractor, Regex extractor, Boundary based extractor, whichever suits well.
Then you need to use While Controller instead of If controller. The While controller it will keep executing the API inside it, until the last skiptoken gets retrieved/ not found - refer the screenshot
If you use If controller - It will execute only once and proceed with other APIs
Since, I don't know the exact response body structure - you can use Regex to fetch the value, something like the below
"#odata.nextLink":"([^ ]+)"
I'm having some trouble with my JMeter test in regards to passing a variable to other requests in the same thread group.
I have 3 requests and one of them is a login request that is only executed once while other 2 requests are looping for one hour. The other 2 requests need to receive a variable 'access token' that is extracted from a login request response in order for them to return a status 200 response.
However, I notice in request header for those 2 requests that the variable 'access token' is not sent in the header although I receive that variable in login request response, extract it with JSON extractor and then send it in the request header.
This my test plan structure:
This is how I extract the variable from the login request:
...and this is how I send the 'access token' variable in request header for other 2 requests:
Everything worked fine until I added the If controller that executes the login request only once and I use this statement in If controller:
${__groovy(ctx.getThreadNum() == 0 && vars.getIteration() == 1,)}
The login request executes correctly and the 'access token' variable is located in the header response.
I can't figure it out, why doesn't variable gets passed to the other two requests?
Different threads don't share same JMeter variables as accessToken
So you need to saved value in JMeter property, for example add JSR223 Sampler
props.put("accessToken",vars.get("accessToken"));
And change your header value to get from JMeter property:
${__P(accessToken)}
vars - JMeterVariables - e.g.
vars.get("VAR1");
props - JMeterProperties (class java.util.Properties) - e.g.
props.put("PROP1","1234");
I'm trying to extract variables returned from one HTTP request, use them in a second HTTP request then extract the variables returned from the second HTTP request.
I then need to use both the first extracted and second extracted variables in a third HTTP request.
I can extract the variables from the first HTTP request and use these in the second HTTP request but cant seem to get the variables extracted from the second HTTP request to then use in the third HTTP request.
Is it even possible to do this?
This is my current set up
It should be straightforward and possible as long as both extractors are going into unique variable names. The Debug Postprocessor will show you the values stored in each variable after a test run. What do you see in those in the context of the third http request?
I want to generate regular expression for the session token ct=KWG3-Q49R-1FAX-YO56(It changes dynamically) in JMeter
First of all, you need to locate the Session Token parameter which is being posted to the Server. It may resides on Request URL, Request Body, or Request Header.
Then, you need to find out the Session Token which gets retrieved from the Server. It may be on any of the previous requests and may retrieved through Response Body, or Response Header.
Now, add the Regular Expression Extractor Post Processor in the request in which Session Token is found. If the original Session Token Expression is as;
ct=KWG3-Q49R-1FAX-YO56
Then try this Regex:
ct=(.*)
Note: Also add a Debug Sampler in your Testplan/ThreadGroup in order to verify your Regex.
I want to use if controller in my jmeter load testing. The test is:
do a post and get back an access token.
use that access token to get the next link.
My issue:
I have the access token and have used the post-assertion->regular expression extractor and got the access token from he http response. But now I don't know how to use the if control and ask it do next test only if the http response code is 200. And second question is can i still pass my regular expression value of access token into the if loop's http header manager?
attaching the screen shot of my jmeter.
Try to use Response Assertion to handle state of Request_Access_Token request (success/failure) depending on Response Code returned and then use IfController along with pre-defined JMeterThread.last_sample_ok jmeter's variable - whether or not the last sample was OK - true/false.
Schema will look like below:
ThreadGroup
Request_Access_Token
Response Assertion
Response Field to Test: Response Code
Pattern Matching Rules: Equals
Patterns to Test: 200
Regex Extractor // your Access_Token extractor
IfController
Condition: ${JMeterThread.last_sample_ok} // will be TRUE if Response Assertion above is TRUE (i.e. response code = 200)
HttpRequest
// send extracted Access_Token along with request
...
