i want to add a step in a jmeter script so as to log out in case of any sample error , and continue next thread , can someone please help me out , how to set an error handling step as to jump to the log out step if any sample error is found .
Thanks!
If you use JSR223 to write a script, you can put the status of step into a variable then using the function if in Jmeter.

I'm using Apache JMeter to send thousands of HTTP requests with 3 seconds of delay in between. The response body is json and starts with {"errors":[ ], ...}. If there is an error it will be in the [ ]. If there is no error than [ ] will be empty.
I want JMeter to pause for a short period of time if it receives an error, and try the request again. So that it'll add in additional buffer when needed.
Do I need a script for this? How can I achieve this?
You can get the number of errors by adding a JSON JMESPath Extractor as a child of the Sampler which returns the JSON and configuring it like:
It will extract the number of entries in errors JSON Array and store it into errors JMeter Variable
Then you can use If Controller to check if the number of errors is above zero, it can be done using __jexl3() function like:
${__jexl3(${errors} > 0,)}
and finally you can introduce a delay using Flow Control Action sampler:
Solution 1
Add a JSR223 Post Processor to the Test Plan level, Thread Group or to a sampler based on your requirement.
Add following code into the script area to check the error and introduce a delay after error if any.
int delayOnErrorInMillis = 5000
if (prev.getResponseDataAsString().startsWith('{"errors":')){
log.info("ERROR !")
sleep(delayOnErrorInMillis)
}
While trying to write Webdriver sampler with Config/listener element ,I have below issue ,Could any team assist me for the same?
1:- In config /listener element/webdriver browser setup file , if we want to enter some value from external resource (' or if we want to save summary report in PC, Is there any procedure to give unique path that can be run in any workstation /pc/ any directory after giving file name only because if we execute in other station or move file in other directory, everytime we need to change file location?Could you please guide me for the same?
While writing webdriver sampler request,I am able to execute script but i am getting below error in log viewer window and also wanted to break functionality as very small unit label for one webdriver sampler request{launch site/login successfully,validate record, logout} so after searching on google , i used sub sample start or samplestart function multiple time , but i am not getting label name in view tree listener result after setting one jmeter property. Could you please guide me for the same?
3:- Could we run three thread group at same time(all three thread run at same time) or some interval (first and sec run on same time but third start after 10 minute)
Thanks you for giving valuable time in advance?
Thanks Amit
You can give only the filename and JMeter will look for the CSV file and write results file into JMeter's "bin" folder (or the place where you launched JMeter from). You can also use __P() function to parameterize the file name or even path, for example if you do set your CSV Data Set Config like:
${__P(testdata,TestData.csv)}
you will be able to override the path using -J command-line argument like:
jmeter -Jtestdata=/path/to/somefile.csv
If you don't provide the property, default value of TestData.csv will be used. More information: Apache JMeter Properties Customization Guide
You're getting this "Invalid call sequence" error because you have duplicate WDS.sampleResult.sampleStart() function call, just remove one of them and that would be it.
Add a Constant Timer as a child of the first request or Flow Control Action sampler at the beginning of the Thread Group 3 and configure them to sleep for 600000 milliseconds.
Just wanna know if this scenario is possible in jmeter:
I will create a website using docker image then i will have to check the exact accessibility time(from creating up to launching/checking the site). Once the requirement is met, the timer will stop and it will give me the exact time on when it is actually up. Also, in the view result tree, i only want to get the last successful status. The View Result Tree will only show the last successful status and will disregard the failed status. This is the sample of my thread that i am using: enter image description here
If you really want to discard non-successful results you can do this using JSR223 Assertion and the following Groovy code:
if (!prev.isSuccessful()) {
prev.setIgnore()
}
where prev is a shorthand for parent SampleResult and setIgnore() function tells the listener to ignore the result in case of failure.

Good afternoon !
I will try to explain you clearly my problem.
The context
I have a JMeter TestPlan which send HTTP requests to a server. I have a Beanshell script to assert each different case of error returned.
302 response code -> OK
200 response code -> ?
In each error 200, I check the response data string to see if it is an error or a correct case. (User error like User don't have correct rights is OK, but Server is unavailable is ERROR and both have 200 as response code.)
Here is my test plan :
The goal
As I have several errors returned by only one assertion script, I am not able to differenciate each error, except by uncollaspe the assertion in a ViewResultTree. But I disable it when launching my test, and I will launch my TestPlan remotely.
I had the idea to manually count each error. All my samples goes in my Assertion script, and goes to the correct if block according to their content. I increment some variables (JMeter.properties in fact) in each block.
int test = Integer.parseInt(props.getProperty("302"));
test++;
props.setProperty("302", ""+test);
I want to display all those variables in a JFrame at the end of my testplan like this :
The problem
My problem is that I don't know how to launch a Beanshell script before and after the TestPlan.
I want a first script to be started before any sample is send, just to initialize all my properties variables to 0 (else, they keep the value of the last TestPlan).
And, I want a second one to display my Frame with all the variables after the test plan is finished. (Currently it is a JFrame but it will not stay like this.)
Tested solutions
1) For my first script, I set a Counter (JMeter > Config Element > Counter) in the beginning of my test plan to 0.
I use it to check if my test already started of not with an If Controller :
I have a Pre-Processor Beanshell with props.set("302","0"); where "302" is my property to count all 302 response code.
It correctly works but I want to know if there is a proper way to do this.
2) Then, for my second script, I tried to use ${JMeterThread.last_sample_ok} in an If Controller aswell but it doesn't work like I expected. If I put it after my sample, it start after all OK assertion, and if I put it at the end of the test plan, it is never called.
How can I run my beanshell script once, after all my threads are stopped (i.e. all sample finished) ?
Thank you in advance, I hope you understood everything !
JMeter SetUp thread group and TearDown thread group are meant for exactly this.
Add your beanshell component to the setUp thread group to do some setup activities before your actual test starts. Similarly the tearDown thread group runs after your test execution is complete.
I have 17 tests in a .jmx that I call from Jenkins. Out of this, 15 runs correctly and return meaningful results. However, the 2 last resturns with a run time of 0ms. I looked at the logs at there is no exception. My question is where (which log file) can I look in this case?
There are different options to detect that your test is doing what it should do.
Assertions
Result File
Log file
The easiest one is using Assertions to check sampler response data. The most commonly used is Response Assertion
Next one is configuring JMeter to save request and response fields you're interested in. See properties, starting from jmeter.save.saveservice in jmeter.properties file. Uncomment and set to true those, you feel may help you to get to the bottom of the issue
The next one is the most flexible and informative. I would suggest to use some logging to get things sorted out. JMeter writes a file called jmeter.log. You can add Beanshell Pre Processor and Beanshell Post Processor to the sampler which run time is 0ms with something like:
In Post Processor:
log.info("Starting test " + sampler.getName() + " at " + new Date());
In Post Processor:
log.info("Response code " + prev.getResponseCode());
log.info("Response message " + prev.getResponseMessage());
log.info("Execution time " + prev.getTime());
etc. You can even see full response data in the log as
log.info(new String(data));
See How to use BeanShell guide for more details on advanced Beanshell scripting.
All stdout and stderr output from the Jenkins build will go to the console output at [Jenkins URL]/job/[job name]/[build number]/console
If you don't see anything useful there, the best approach is to run the JMeter tests outside Jenkins, but on the same machine and under the same user environment that Jenkins would use. You may need to enable some extra debugging info; see this link for some tips.
