How to compute total time taken to complete a thread group in JMeter?

Question

I am looking to see if it's possible to easily compute the total time taken to complete a Thread Group. In my case, I have a thread with 100 concurrent users with 1 HTTP request. I would like to know how long did it take to complete requests from all 100 users. I tried using Transaction controller with Aggregation Report but it doesn't seem to capture the value across all concurrent users.

Thanks, J

1. Add tearDown Thread Group to your Test Plan. It is executed after all thread groups so it is a good place to measure test duration.
2. Add JSR223 Sampler as a child of the tearDown Thread Group

3. Put the following Groovy code into "Script" area:

   def testStart = new Date(vars.get('TESTSTART.MS') as long)
   def testEnd = new Date()
   
   use(groovy.time.TimeCategory) {
       def duration = testEnd - testStart
       log.info("Test duration: ${duration.seconds}")
   }
   

4. Once test finishes you will see its duration in seconds in jmeter.log file.

   

   You can also use ${duration.hours}, ${duration.days}, etc.
