I'm looking out for a tool that supports recording option in web on the tasks that I perform (search and result analysis).
I finally rerun the recorded script and calculate the time that is taken for each page that is loaded (generally based on the search criteria) within the web.
Once the page loading exceeds the defined time, the exceeded time should be highlighted.
The reports on this should be automatically saved.
The above scenario was tried using jmeter, but I was not able to set benchmark and automatically set the scenario as failed when the page load exceeds the defined number.
Please suggest a tool that could be used for the above mentioned scenario, and if the same could be done using Jmeter that I'm missing out.
Thanks in advance..!
In JMeter you have :
Duration Assertion which you can utilize to set the response time threshold. If response time exceeds the time set in the duration assertion JMeter will automatically mark the relevant sampler(s) as failed
SMTP Sampler which can be used for sending JMeter test results to the specified recipient(s). Add a tearDown Thread Group to your Test Plan (tearDown Thread Group is being executed after all other Thread Groups), put SMTP Sampler under this tearDown Thread Group and configure it to send .jtl results file at the end of the test. See Load Testing Your Email Server: How to Send and Receive E-mails with JMeter article for example configuration.

I have been looking into postman and JMeter for a school project and I know that you can run a postman test and get results using JMeter. I have also been told that the main reason for JMeter is that you can run that test many times in JMeter unlike postman.
Does anyone know how to do this? got any links or resources you can share or just know the answer yourself?
I have been searching online for answers and I have connected the 2 application through using the HTTP(S) Test Script Recorder but this only provides me with 1 result and I have been unable to find anything that talks about using this to run the test many times.
If anyone is able to provide me with a solution it would be much appreciated
First of all you need to convert your Postman test into a JMeter test, the approach is as simple as running test in Postman using JMeter as the proxy:
Configure JMeter for recording. The fastest way is using JMeter Templates
feature
From JMeter's main menu choose File -> Templates -> Recording and click "Create". You should get a Test Plan structure like:
Expand HTTP(S) Test Script Recorder and click "Start"
Prepare Postman for recording.
From Postman's main menu choose File -> Settings -> Proxy and configure it like:
Run your collection in Postman
JMeter should generate relevant HTTP Request samplers under the Recording Controller
Now expand Thread Group and set the desired number of threads (virtual users) and loops (iterations)
Run your test in JMeter
Inspect results using View Results Tree listener
More information: Building a Web Test Plan - Adding Users
After you record the script in JMeter, you can run multiple times in Thread Group element by (increasing Threads Number to run script with multi threads or) increasing Loop Count, if you want to just repeat the script
thread group element controls the number of threads JMeter will use to execute your test. The controls for a thread group allow you to:
Set the number of threads
Set the ramp-up period
Set the number of times to execute the test
Increasing User Threads in my JMeter performance testing, found some of the requests called before login. So those requests were failed.
My Test plan is below
In .csv file, added 1000 users with {email, password} and given to Login Http Request -> CSV Data Set Config. I'm extracting {uid} from login response and stored in uid
Second Random Controller, have multiple HttpRequest's, every request needs {uid}.
This works on below 50 user threads. But when i increased threads, some Random Controller ==> Http Request sends without uid
See, this one is with uid
But this one is with out uid
Can any one help me, how we can achieve this?
I can see 2 possible reasons:
Your application gets overloaded therefore your Login Request doesn't return correct uid so your extractors fail
Your JMeter intsance get overloaded so JMeter cannot handle 50+ users as you are running it in a non-optimal way
I would start with point 1 by temporarily enabling storing requests and responses data into .jtl results file by adding the next lines to user.properties file:
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.responseHeaders=true
This way you will be able to see response data for failed requests using View Results Tree listener and will be able to identify where the test fails.
Other things worth checking/implementing:
check your application logs
setup monitoring of baseline OS health metrics (CPU, RAM, Disk/Network IO) on both JMeter and application under test sides, you can use JMeter PerfMon Plugin for this
Make sure you're following JMeter Best Practices, i.e.
Run your test in command-line non-GUI mode
Increase JVM heap size
Switch to JSR223 Test elements instead of Beanshell
My jmx file has 30 requests , 30 users, and response data may very according to the user logged. I am using view result tree as listener, my question is how to know for which user for which a request failed to get a response from server?
There are multiple options, to provide exact solution we need to know more details.
JMeter provides information about thread (virtual user) number as "Thread Name"
You can append the relevant JMeter Variable to the sampler name:
N.B. Don't use View Results Tree listener for anything but tests development and debugging as it is very resource intensive, when it comes to load test execution it will consume lots of the RAM and it may ruin your test. Run you test in command-line non-GUI mode and use listeners to analyse the results file after test completion.

When I have given 500 concurrent users load via jmeter my server throwing error message but the same time I have called same request via browser showing proper response. How it is possible? Is there any settings in jmeter for avoiding same.
It is hard to say what can go wrong without seeing your JMeter configuration, full server response, JMeter and application under test logs and network dump for browser and JMeter.
The whole idea of performance testing is mimicking real user as close as possible, so you need at least
Add HTTP Request Defaults and set JMeter to:
Download embedded resources
Use concurrent pool of 2-5 threads
Add HTTP Cookie Manager
Add HTTP Cache Manager
Add HTTP Header Manager
Correlate any dynamic parameters
Simulate any specific application behaviour (i.e. AJAX calls)
etc.
In addition to above recommendations: ideally given "good" JMeter you shouldn't see any "response messages", you should see a number of errors in final report so double check you:
Run JMeter in non-GUI mode
Storing only those metrics which are absolutely required
Follow other recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure
beside, what Dmitri described above, I would also check the actual throughput the server returns in either cases.
Throughput depends a lot on the timers you configured in Jmeter to simulate think time.
Jmeter has no rendering and no javascript engine, so each thread is much much faster than a real browser.
I am new to Jmeter and trying to understand what all can be achieved using Jmeter. I want to perform endurance or soak testing of a application using Jmeter, i.e. I want to run a particular script for a particluar number of users for a period of 3 hours.
What all options are available to me and what is the best availablelistener to monitor the result?
Please help. Kindly add if I am missing anything that I should know before starting with soak testing?
For setting up the numbers of users and runtime of the test you use a Thread Group. Setting the runtime is done by checking the Scheduler check-box and specifying Duration.
Of the original listeners in JMeter I have found myself most oftenly just using the plain Summary Report. But JMeter Plugins gives additional listeners which may be better, it depends on what you want to measure. The JMeter Plugins also gives additional thread groups, where you can specify e.g. an increasing load over time.
Use a Thread Group to set up your number of users and the duration of your test (using the scheduler of the Thread Group).
Then add all the samplers and logic controllers you need to perform your testing.
Next, add a Summary Report listener to get an overview of your results (min/max/average and such), and add a View Result Tree listener to get an overview of EACH step your testplan is taking. This Tree listener is great to actually see what jmeter is doing, and to debug your tesplan.
BTW: if you add a HTTP Request Defaults object, you can set your URL and options in there, and don't need to add it to each and every sampler again. Especially works like a charm if you start using regexp extractors and such.
