I am looking for a way to use headers at Jmeter from centralized location.
Currently i am using like:
Where "HTTP Header Manager" is Embedded in every single call.
But, i don't find this usage very good, especially if some change is done, i need to change every single call.
Is there any way i can create centralized 'method', so i can call in every single call, rather than 'Hard coding' them?
HTTP Header Manager (as well as other Configuration Elements, Pre-Processors, Post-Processors, Timers, Assertions and Listeners) obey JMeter Scoping Rules therefore it is enough to put the HTTP Header Manager at the same level as all the Samplers and the header(s) defined there will be applied to all of them.
If you want to override the particular header - add another HTTP Header Manager as the child of this or that particular Sampler and the header will be overwritten for this request.
You can put Header Manager in same level of requests and it will effect all requests in same hierarchy
JMeter now supports multiple Header Managers. The header entries are merged to form the list for the sampler. If an entry to be merged matches an existing header name, it replaces the previous entry. This allows one to set up a default set of headers, and apply adjustments to particular samplers. Note that an empty value for a header does not remove an existing header, it justs replace its value.

I need to extract static content(js, css, png) from the response and trigger dynamic http requests with static content.
Can you please let me know if there is any efficient way to extract and pass it http requests.
For example:
From below tags, Need to extract value from src of tag and store it in list/array and trigger dynamic request based on the number of values.
script asp-add-nonce="true" src="/abc/jquery.js"></script
script asp-add-nonce="true" src="/abc/xyz.min.js?v=skjdfjkdjfdfjlkjlkk"></script
In the above example, we have two values matching the condition, so we need to trigger below two dynamic requests.
If we have 5 tags matching condition, the need to generate and trigger 5 requests in JMeter.
http://appname/abc/jquery.js
http://appname/abc/xyz.min.js?v=skjdfjkdjfdfjlkjlkk
Appreciate if anyone can help on this.
JMeter can automatically parse response and look for images, scripts, styles, fonts, etc.
All you need to do is to tick the relevant box under "Advanced" tab of the HTTP Request sampler

Alternative option is extracting them using a suitable Post-Processor and run the requests using ForEach Controller if you need sequential requests or Parallel Sampler if you need to send the requests at the same moment.
Is there a way for all Receive samplers to ignore specific responses in JMeter and wait for the one that we are interested?
To be more precise, we have created a jmx file that contains a large flow like a user would create on the browser. Each request sent is followed by a response, so we use a request handler followed by the corresponding receive handler for each call. And everything seems to work fine.
But there are cases that another kind of response may arrive, which is not the one we expect in our flow, but it is triggered by another independent mechanism. You can think of it like notifications sent to the user that is doing the flow and are independent of the flow itself, but theu are received in the channel (for us inside the websocket connection).
So we are trying to find a way to ignore a specific set of responses that may come while we are running the tests.
We firstly tried to add a While Controller in each receive sampler that checks if the content is of the desired type and if not loops again. But this solution has 3 disadvantages :
we have to add the sampler for the specific receive twice - one before the while element and one inside the element because we have to first extract the received data and while does not execute its contents before doing the while condition check
we have so many pairs of send-receive in our jmeter test script , that we have to add so many while controllers inside the script
since the received message may not be of the type we expect but another one that we want to ignore, then we cannot add a Response Assertion because it will fail if the notification arrives, so we have to verify the content indirect -> in the condition of the while loop
We use apache-jmeter-5.3.
So we are wondering if we could do another kind of configuration in order to avoid all these while loops.
It may be irrelevant to the solution, but we use websocket through "WebSocket Samplers by Peter Doornbosch".
Thanks
You don't have to, just amend your While Controller's condition to accept undefined variable as well
Sounds like a potential use case for using Module Controller to avoid code duplication
If you're getting the response you don't expect you can change the response body using JSR223 PostProcessor to the one you expect, example code
if (!prev.getResponseDataAsString().contains('foo')) {
prev.setResponseData('foo', 'UTF-8')
}
My HandleHttpRequest receives multiple files in a request. I need to process all these files and then only I need to send response. I looked at its source to extend it but there is no easy way as most of the methods are private.
I request a new attribute (something like flowfiles.count) to be added to the flow files so that a wait/sync mechanism can be implemented.
Or define a method in HttpContextMap to get the number of flowfiles which can be provided at the time of register.
Is there any solution that I can use for now?
Thanks in advance
starting from nifi 1.8.0 the feature exists.
from additional information of the HandleHttpRequest 1.8.0 processor:
To handle requests with Content-Type: multipart/form-data containing multiple parts, additional attention needs to be paid. Each part generates a FlowFile of its own. To each these FlowFiles, some special attributes are written:
http.context.identifier
http.multipart.fragments.sequence.number
http.multipart.fragments.total.number
These attributes could be used to implement a gating mechanism for HandleHttpResponse processor to wait for the processing of FlowFiles with sequence number http.multipart.fragments.sequence.number until up to http.multipart.fragments.total.number of flow files are processed, belonging to the same http.context.identifier, which is unique to the request.
I have 3 Rest API's, each one of them dependent on each other, how to create test plan for them, jmeter firing those urls non sequential order i want it in Sequential order, when i check on "view result tree" i am getting 403 error.
Are they in the same thread group? If so, they ought to fire sequentially in order.
If the three are dependent on each other you need to take following steps:
Add thread group
Put the API's one after the other based on the values and dependency.
Extract the value from the first API and pass it to the next using Post Processors like Regular Expression Extractor or JSON extractor.
You are seeing 403 which is related to forbidden access, it means that you are not allowed to access that particular URL or missing some authentication token or cookies or username/password.
So add the authorization manager to your test plan if that's missing and send appropriate values.
I'm building a web-based reporting tool that queries but does not change large amounts of data.
In order to verify the reporting query, I am using a form for input validation.
I know the following about HTTP GET:
It should be used for idempotent requests
Repeated requests may be cached by the browser
What about the following situations?
The data being reported changes every minute and must not be cached?
The query string is very large and greater than the 2000 character URL limit?
I know I can easily just use POST and "break the rules", but are there definitive situations in which POST is recommended for idempotent requests?
Also, I'm submitting the form via AJAX and the framework is Python/Django, but I don't think that should change anything.
I think that using POST for this sort situation is acceptable. Citing the HTTP 1.1 RFC
The action performed by the POST method might not result in a
resource that can be identified by a URI. In this case, either 200
(OK) or 204 (No Content) is the appropriate response status,
depending on whether or not the response includes an entity that
describes the result.
In your case a "search result" resource is created on the server which adheres to the HTTP POST request specification. You can either opt to return the result resource as the response or as a separate URI to the just created resource and may be deleted as the result resource is no longer necessary after one minute's time(i.e as you said data changes every one minute).
The data being reported changes every minute
Every time you make a request, it is going to create a new resource based on your above statement.
Additionally you can return 201 status and a URL to retrieve the search result resource but I m not sure if you want this sort of behavior but I just provided as a side note.
Second part of your first question says results must not be cached. Well this is something you configure on the server to return necessary HTTP headers to force intermediary proxies and clients to not cache the result, for example, with If-Modified-Since, Cache-control etc.
Your second question is already answered as you have to use POST request instead of GET request due to the URL character limit.
