I am facing the following problem:
I have multiple HTTP Requests in my testplan.
I want every request to be repeated 4 times if they fail.
I realized that with a BeanShell Assertion, and its already working fine.
My problem is, that I don't want requests to be executed if a previous Request failed 5 times,
BUT I also dont want the thread to end.
I just want the current thread iteration to end,
so that the next iteration of the thread can start again with the 1st request (if the thread is meant to be repeated).
How do I realize that within the BeanShell Assertion?
Here is just a short extract of my code where i want the solution to have
badResponseCounter is being increased for every failed try of the request, this seems to work so far. Afterwards, the variable gets resetted.
if (badResponseCounter = 5) {
badResponseCounter = 0;
// Stop current iteration
}
I already checked the API, methods like setStopTest() or setStopThread() are given, but nothing for quitting the current iteration. I also need the preference "continue" in the thread group, as otherwise the entire test will stop after 1 single request failed.
Any ideas of how to do this?
In my opinion the easiest way is using following combination:
If Controller to check ${JMeterThread.last_sample_ok} and badResponseCounter variables
Test Action Sampler as a child of If Controller configured to "Go to next loop iteration"
Try this.
ctx.setRestartNextLoop(true);
if the thread number is 2, i tried to skip. I get the below result as i expected (it does not call b-2). It does not kill the thread either.

I am having a thread group containing HTTP request, JDBC request, If and While controller. Whenever I try to run thread group more than 1 time (using loop controller or by specifying number of times execution required in thread group), then HTTP, JDBC request are executed but while controller is not getting executed.
post using Debug sampler found that index of while controller is not getting changed hence it is not getting executed post 1st time.
While Controller finishes its execution when (if) its "Condition" becomes false
When you enter 2nd iteration of the Thread Group the "Condition" is still false so threads (virtual users) don't enter the While Controller
You need to reset the variable(s) used in the While Controller so the "Condition" of the While Controller becomes true again somewhere in the end of the 1st iteration, it can be done using either Set Variables Action sampler or using JSR223 Sampler or whatever is the most convenient way for you to do this.
I have 4 transaction controllers named
Trans_api1
__Http Request
Trans_api2
__Http Request
Trans_api3
__Http Request
Trans_api4
__Http Request
that contain Http Requests, However when I run my test plan, I want them to run in numerical order but then they run randomly. How do I fix the order to it runs from 1-4?
Each JMeter thread (virtual user) runs Samplers upside down so you don't need to do anything, your requests are executed from top to bottom already. If you run your test with 1 user - you will see that requests are being executed sequentially.
If you're seeing some "mess" most probably it's caused by concurrency, like
1st user starts 1st request
2st user starts 2nd request
2nd user starts 1st request
1st user starts 3rd request
etc.
You can see this yourself if you add ${__threadNum} function as the prefix or postfix for your request (or transaction controller) label and eventually ${__groovy(vars.getIteration(),)} function to display the current loop number
With 1 user:
With 2 users:
With 2 users and 2 iterations:
As it evidenced by the above images each users executes samplers sequentially on each iteration, these "inconsistencies" are misleadingly interpreted due to concurrency

So I have a workflow which is supposed to throw an error after a certain condition is satisfied. (False condition) As you can see in the log directly below, it works: I do a loop exit first for the group 'coms' and an error is thrown. However, Flowgear seems to only read the last executed node and then determine the workflows status from that. Since the loop finishes last and is successful, if you look in the second log, you can see that the workflow has been evaluated as 'successful' although an error was thrown inside.
Any ideas how to make the loop break? Also why does flowgear only consider the last node? There should be an option in the error node to stop all execution.
Iterator nodes (Splitter and Loop) will consume the errors. The only way at this stage to get the workflow to return an error is to cause an error in the AnyError or UnhandledError part of the workflow. I've created a workflow to demonstrate this here: http://flowgear.me/s/UdpGBbd
Hope this helps.
In normal applescript, the script is executed down the page, and so any code in loops for every 5 seconds will only run while the loop is running - there is no way to have a single function run every few second regardless of what the script is currently doing or where it is in the script (that I know of). In cocoa-applescript, however, is there a way to run a handler every 5 seconds, at all times, no matter what it is currently doing? Here is what it should be doing in my cocoa-applescript app:
on checkInternetStrength()
do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep 'agrCtlRSSI:'" -- this being the script which returns the line containing the signal strength
set SignalStrength to result
set RSSIcount to (count of characters in SignalStrength)
set SignalStrength to ((characters 18 thru RSSIcount of SignalStrength) as string) as integer -- this to turn SignalStrength into just the number and not the whole output line
set SignalStrength to (100 + SignalStrength) as integer
set SignalBar's setIntValue_(SignalStrength) -- SignalBar being the Level Indicator described below
end checkInternetStrength
Summed up, it runs the airport command to check internet connection, turns this into a number from 1 to 100 and uses this on an NSLevelIndicator (100 maximum) to show current signal strength graphically. Now, there is no point having this run once or when you hit a button - that is an option, but it would be nice if it updated itself every, say, 5 seconds with the realtime value. So is there any way to have a process which runs every 5 seconds to do this, while still enabling full functionality of the rest of the script and interface - i.e. as a background process? Comment if you need more extracts from the script.
Example
In Unity-C# scripting, the 'void Update() {code}' will run the code within it every frame while doing everything else simultaneously, so a cocoa-applescript version of this might be an answer, if anyone knows.
I Dont believe this is possible but what I had a similar problem before, what i do, I have an external applescript applicaion that is hidden the repeats the commands, the only problem is, it wont send it back to the app, you'll have to make the external applescript app do it, like
display notification, etc..., in the applescript apps "Info.plist" you can add this:
<key>LSUIElement</key>
<string>1</string>
To make the app run invisibly, but sorry i dont think you can run a handler in the app its self
I am trying to send an HTTP request via JMeter. I have created a thread group with a loop count of 25. I have a ramp up period of 120 and number of threads set to 30. Within the thread group, I have 20 HTTP Requests. I am a little confused as to how JMeter runs these requests. Do each of the 20 requests within a thread group run in a single thread, and each loop over a thread group runs concurrently on a different thread? Or do each of the 20 requests run in different threads as and when they are available.
My other question is, Over each loop, I want to vary the body of the post data that is being sent via the HTTP request. Is it possible to pass the post data body via a file instead of inserting the data into the JMeter Body Data Tab as show below:
However, instead of doing that, I want to define some kind of variable that picks a file based on iteration of the threadgroup that is running, for example, if it is looping over the thread group the second time, i want to call test2.txt, if the third time test3.txt etc and these text files will contain different post data. Could anyone tell me if this is possible with JMeter please and if so, how would I go about doing this.
Point 1 - JMeter concurrency
JMeter starts with 1 thread and spawns more threads as per ramp-up set. In your case (30 threads and 120 seconds ramp-up) another thread is being added each 4 seconds. Each thread executes 20 requests and if there is another loop - starts over, if there is no loop - the threads shuts down. To control load and concurrency JMeter provides 2 options:
Synchronizing Timer - pause all threads till specified threshold is reached and then release all of them at the same time
Constant Throughput Timer - to specify the load in requests per minute.
Point 2 - Send file instead of text
You can replace your request body with __fileToString function. If you want to parametrize it you can use nested function to provide current iteration - see below.
Point 3 - adding iteration as a parameter
JMeter provides 2 options on how you can increment a counter each loop
Counter config element - starts from specified value and gets incremented by specified value each time it's called.
__counter function - start from 1 and gets incremented by 1 each time it's being called. Can be "per-user" or "global"
