[Res]Thread setting in load test scenario

Hi,

You can use the strategy Burst under variable load,
http://www.soapui.org/Load-Testing/simulating-different-types-of-load.html#3-variable-load-strategies
http://www.soapui.org/Load-Testing/loadtest-execution.html
Thread 20
limit 100
Delay 10 seconds

This should work

Thanks,
Jeshtha

Jeshtha,
Thanks for the suggestion. I tried:
limit:6
Threads: 2
Delay: 5

Each thread reads a file in my local directory. But I got this error.

Thanks,
Larry

Hi,

The error indicates the file not being found. Can you verify that you are not getting this error when you run your TestCase? And if you do a simple strategy of one run of one thread for your LoadTest, do you still get the error?

Hi Giscard,
Sorry for the distraction. I think the error caused by my groovy scripts enable/disable setting.
However, I tried to write threadIndex ID into log file to confirm if this thread/burst setting picks up uniq file. My setting is below:
Limit: 6
Threads: 2
Strategy: burst
burst Delay: 5
Burst Duration: 60

and get such records in my log file:
Mon Feb 03 16:39:06 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:06 EST 2014thrdIndx= 1 ...j= 0 SE_Text_840.txt
Mon Feb 03 16:39:26 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:27 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:28 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:29 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt

As you can see, the last 4 threads are the same threadIndex and can't pick up uniq file. But I also can pick up uniq file (uniq thrdIndex) from 'Simple' Strategy in load test setting.

Thanks,
Larry

Hi!

Could you provide the contents of the Groovy Script that picks up the unique file?
Also, it would be great if you could elaborate on what is the the expected behavior here? All log entries should refer to a unique file?
When are you writing to the log file? In the Groovy Script?

def thrdIndex = context.ThreadIndex
j=0


fileIndex = thrdIndex
myFileName = list[fileIndex].toString() //get selected filename

myFile = new File(myFileDir + myFileName)

toFile = new File(toFileDir + toFileName)
toFile.append("\r\n "+ now + " ...thrdIndx= "+ thrdIndex + " ...j= "+ j +" "+ myFileName)//write picked up filename into this file

In my 1st post I mentioned the expected behavior. In the last post, my expected behavior was even more simple.
1. start threads 1/2
2. wait 5 sec
3. Start threads 3/4
4. wait 5 sec
5. Start threads 5/6

Yes, all done in groovy script.

BTW, my simple strategy log records:
Mon Feb 03 16:51:26 EST 2014 ...thrdIndx= 1 ...j= 0 SE_Text_846.txt
Mon Feb 03 16:51:26 EST 2014 ...thrdIndx= 2 ...j= 0 SE_Text_847.txt
Mon Feb 03 16:51:26 EST 2014 ...thrdIndx= 0 ...j= 0 SE_Text_845.txt

Thanks,
Larry

Hi!

But according to this:

def thrdIndex = context.ThreadIndex
j=0


fileIndex = thrdIndex
myFileName = list[fileIndex].toString() //get selected filename

There will be a unique file per thread, not by call to the GroovyScript, thus

Mon Feb 03 16:39:06 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:06 EST 2014thrdIndx= 1 ...j= 0 SE_Text_840.txt
Mon Feb 03 16:39:26 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:27 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:28 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:29 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt

is expected since log entry 1 and 3 - 6 all are for the same thread (1) and thus referring to the same file.


Am I misunderstanding something here?

Hi Erik,

My runtime setting is:
Limit: 6
Threads: 2
Strategy: burst
burst Delay: 5
Burst Duration: 60

According to Jestha's reply on 30 Jan 2014 15:39, I expect to see 6 threads to run in such sequence:
thrd 1&2
wait 5 sec
thrd 3&4
wait 5 sec
thrd 5&6

Each thread runs groovy script (write data into logfile) once, so I should have seen thrdIndex in log file as below:
Mon Feb 03 16:39:06 EST 2014thrdIndx= 0 ...j= 0 SE_Text_839.txt
Mon Feb 03 16:39:06 EST 2014thrdIndx= 1 ...j= 0 SE_Text_840.txt
Mon Feb 03 16:39:26 EST 2014thrdIndx= 2 ...j= 0 SE_Text_841.txt
Mon Feb 03 16:39:27 EST 2014thrdIndx= 3 ...j= 0 SE_Text_842.txt
Mon Feb 03 16:39:28 EST 2014thrdIndx= 4 ... ...
Mon Feb 03 16:39:29 EST 2014thrdIndx= 5 ... ...

Hi,

I think it is difficult to control the behavior to determine which thread will be picked, so if you really want to control this behavior my recommendation would be to script it yourself. You can look at the Script strategy. You can look it here http://www.soapui.org/Load-Testing/simu ... strategies
