Custom Sampler: Force all setupTest methods to be invoked before
runTest methods
Hello,
I have written a Custom Sampler by extending "AbstractJavaSamplerClient". My
sampler is very simple, it just logs the method being invoked.
If i run the sampler for 2 threads with "loop count" of 1, I see the
following output:
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler Constructor
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler setupTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler runTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler Constructor
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler setupTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler runTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler teardownTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler teardownTest
Here you will observe that the "runTest" method of the first thread is
invoked before the "setupTest" of the 2nd thread. For my test I need to
ensure that all threads have their setupTest method invoked before any of
them have their "runTest" method ivoked.
Does anyone know how I can do this?
Thanks,
Paul.

Excellent,
The thing I was missing was the fact that you can put variables in the UDV.
Apart from adding complexity to my Sampler, I think this is a good solution.
I'll do this,
Thanks a lot for your help,
Paul.

RE: Custom Sampler: Force all setupTest methods to be invoked before runTest methods
Posted by Ian Blavins <ib...@temenos.com>.
G'day
I had the same problem.
I define a user defined variable to hold the thread count. I populate the Number of Threads field on the thread group from the UDV (the field accepts an expression). Then you have the thread count in a variable which you can give to the sampler in the normal way without having two places to update the thread count.

Ian,
I see what you mean now. We have considered this approach already and we
plan to use it as a fall back. The problem with the approach is as you
suggest, you need to tell the sampler how many client threads to expect.
I've inspected the JavaSamplerContext and can't find a thread count.
Thanks,
Paul.

RE: Custom Sampler: Force all setupTest methods to be invoked before runTest methods
Posted by Ian Blavins <ib...@temenos.com>.
G'day
I wasn't suggesting static for the connection - just to control initialization. Don't let any thread exit from initialization until all have completed initialization. You will need a static variable to keep count of threads that have initialized and a static synchronized method to update it in a thread safe manner. You will also need to tell the sampler the number of threads in the run. You may be able to get this from the environment with a method call or you may have to pass it in.
There are probably other ways to do this if getting the number of threads in the run proves awkward.

Hi,
Thanks for the quick reply. Static variables would be a good idea, however,
I require that each thread has it's own connection, in order to simulate
multiple separate users. Sharing a connection through a static variable
would break my test unfortunately.
For some reason, the system I am testing requires that all connections are
established before any of them are used. Therefore I really need to ensure
all the setupTest methods are invoked before any of the runTest methods are
invoked.
Thanks for the help,
Paul.

G'day
Because they all run under one JVM all instances of the sampler within a JMeter server can share memory through static variables.
If you are familiar with static variables that should be enough to get you going.

Subject: Custom Sampler: Force all setupTest methods to be invoked before runTest methods
Hello,
I have written a Custom Sampler by extending "AbstractJavaSamplerClient". My
sampler is very simple, it just logs the method being invoked.
If i run the sampler for 2 threads with "loop count" of 1, I see the
following output:
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler Constructor
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler setupTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler runTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler Constructor
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler setupTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler runTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler teardownTest
INFO 03/23, 02:49:18 hat.test.jms.test.DummySampler teardownTest
Here you will observe that the "runTest" method of the first thread is
invoked before the "setupTest" of the 2nd thread. For my test I need to
ensure that all threads have their setupTest method invoked before any of
them have their "runTest" method ivoked.
Does anyone know how I can do this?
Thanks,
Paul.
