I wanted to stop jmeter if my conditional logic is false,suppose if one of my conditions gets failed then i need to stop immediately all my threads(jmeter) during run time,so that is there any way stop it running time through code not manually(not thru action to be taken after a sampler error)
Thanks,
in advance
There is 2 options for you:
If your condition can be expressed in If Controller, then use standard Test Action Component to stop test
If you want to stop test when response time or error rate increases some threshod, then use custom AutoStop Component

Can I perform a test that will stop in some step, and after I perform something manually in my system I will tell Jmeter to resume running the test?
is it possible in JMeter to pause a test in the middle and then to resume it?
I don't know about out of the box solution in JMeter, so you need to add such logic yourself.
For example you can do a While controller with a variable set to true at start, inside loop read from file until it's value is false and then exit loop and resume test. You can even use StringFromFile function as ${__StringFromFile(flagResume.txt,,,)}
In your manual operations add to file the value false, and then the JMeter test will resume.
What is the nature of the task you need to do manually? I'm pretty much sure that it is doable via JMeter itself, JMeter Plugins or Groovy Scripting.
If I'm wrong or you have a very specific scenario one of possible solutions would be adding Constant Throughput Timer to your Test Plan and define desired Requests per Minute rate using JMeter Property via __P() function
Whenever you need to "stop" the test you can set the "throughput" property to 0 using i.e. Beanshell Server
We're running a test case for load testing, over different servers. What we want to do is, given that test case, stop if we can see a performance decrease, based on a response time threshold.
What we have now is threadgroup defined, and inside it, an HTTP request defined plus a view table for output. What should I do to put this control in there?
Add Duration Assertion and specify threshold there
In your Thread Group set "Action to be taken after a Sampler error" to Stop Test.
Above steps will stop your test after first occurrence of response time exceeding the threshold.
See How to Use JMeter Assertions in Three Easy Steps article for more information on how to conditionally set pass/fail criteria in your JMeter test.
P.S.
Remove View Results Table listener (or disable it) during load test execution as it consumes a lot of resources.
Run your load test in non-GUI mode as JMeter GUI is not designed for running the actual load test and may be a bottleneck in case of more or less severe load.
Writing a Web Performance Test for a process that will run for an undetermined time, and have to put a refresh command in a while that runs until the process state indicates it is done.
The refresh command consumes about 3 seconds. so do not want it running constantly in the loop. So, am trying to find a sleep/wait function to stop the execution between loops.
The only reference i've found is for Thread.Sleep which seems to do the job.
BUT, this method seems to also stop the test's timers. so, however many times the loop runs, and whatever the actual time taken by the process, the test report will only show the cumulative time of the refresh statements.
Is there another method that will not stop the test's timers?
If the refresh is in a loop within the Web Performance Test then set a suitable "think time" on the request. This will pause the test after the response is received. (Think times are normally used to simulate the time a person spends reading a web page and filling in forms etc before the next request is issued.)
Think times are set via the properties of the request. Think times (also reporting names) for all requests in a test can be viewed and modified using the "Set request detail" command accessed using the (rightmost) command icon in eth web test editor.
Think times can also be set or adjusted in the PreRequest method of a WebTestRequest plugin.
I'm trying to run a scenario that ramps up each thread by logging them in once, loops through an business action for an hour with pacing, and logouts as it ramps down.
Ideally the threads should not log out all at once, as such it I wanted to find a way to execute a logout action for each thread ramping down.
I have tried using stepping and ultimate thread groups, however for ramp down, the threads are being stopped.
In addition, I have tried the following scenario: 1) login, 2)runtime controller scheduled for one hour with the business action, 3) logout. This however, results in premature aborts for the threads that are still executing the business action once it reaches one hour.
Any help, even implementing this in beanshell, would be greatly appreciated.
You can just use a TearDown Threadgroup. That will always be executed once your test is over.
You can use a thread group which sets a jmeter property, let's call the property "isRunning", in a pre or post processor, next that thread has a test action set to pause for the duration of the test. After the pause set the property "isRunning" to false.
When the user logs on in another thread group (your test case) grab the "isRunning" property and store the value in a jmeter variable for the thread. Once the user logs in put your business case in a while loop with the jmeter variable created using the "isRunning" property as the condtion.
Get the value of the "isRunning" property somewhere towards the end of your business case and update your jmeter variable. Put the log out controller outside of the while loop. When the first thread group sets the "isRunning" to false, the while loop in your other threads will finish executing the use case and log out when it sees that the while condition is no longer met.
If you use any type of random think timers and ramp time, the threads should essentially step down on their own, due to ramp time offsetting the start of the use case and random think times.
Not sure if this is the best way to go about this, but I needed to do the same thing you are looking for and this proved to be a feasible workaround.
I'm using JMeter to run a functional test to update the password of a lot of users (22K). I've separated the users in 2 scripts and used a Ultimate Thread Group with Start Threads Count = 100, which is the value with which I got less errors, however I still got 1.5% transactions failed, and I need to rerun only this failed threads, because all users need to have the same password.
I've tried to get answers to this specific problems, but I have only found ways to prevent this from happening, like using a While controller with a timer, or logging the full response for failure, but I haven't found if there is a way to specifically rerun the failed threads.
Does anyone know if this is possible?
You will have to do following.
Use JSR223 sampler to set the rescode=0
While controller with (if rescode!=200)
HTTP Sampler
JSR223 post processor as javascript as the scripting language.
Store response code using prev.getResponseCode()
e.g. vars.put("rescode", prev.getResponseCode());
You might have to add some more intelligence to the script to avoid infinite loop.
Another approach to solving the problem would be to anticipate errors on some of the password update calls and build a data file upon failure with the information you need.
For Example:
Create a regular expression post processor that has default value of false, and template value of true. Make the expression match the expected response, and fail if the sample fails.
Then, after that sampler, you can add an if statement based on the new true/false variable. If it is false, you know the previous password update failed. Inside the if statement, add a dummy sampler with response data containing all the information you need to know which accounts you must retry.
Then, add a simple file writer to this dummy sampler, and log the dummy sampler response data to a file. At the end of a test run this data file would contain all the information you need to re-try all failed accounts.
Sadly this is a slightly manual process, but I'm sure with a little creativity you could automate recursive test runs until the re-try file is empty. Beanshell file IO might let you handle it all inside a single test run.
