threading multiple test suites, each suite gets its own thread

[aldentaylor]

Hi all,

We use testng for integration testing and this is working very well.
We define a suite for each scenario that we want to test which can be
made up of multiple tests. We invoke this process via the Ant testng
task.

What I'm wondering is if there is a way to thread the running of each
suite? That is to say, the suite itself should run in a single thread
with each test running in the specified order, but each suite being
included should run in a separate thread.

So 4 suite.xml files supplied to the <testng> task would run in 4
threads.

We use the reporting capabilities to produce a single report showing
all suites that were run in the test, so we don't want to just invoke
testng once for each suite in the ant <parallel> task.

Is there any way to achieve this?

Cheers,
Alden

Hi Alden,

Interestingly, this is the first time that this feature request has come up :-)

It's not possible at the moment, as you probably know, since the parallel configuration can only be specified in <suite> or <test> but not at the "meta suite" level.

I'll look into allowing to specify a "parallelSuites" parameter on the command line or ant which, when passed, will run each suite in its own thread.

Thanks Cedric.

Anyway we can get there by extending the org.testng.TestNG class and
defining this as the suiteRunnerClass?

Don't really know the internals of how TestNG is designed, so I'm
asking if this is a viable solution to explore or not.

If not, can we contribute to testNG to add the capability with your
direction?

Many thanks,
Alden

Hi Alden,

I just finished implementing this feature. Download the beta (http://testng.org/beta ) and use "java org.testng.TestNG -suitethreadpoolsize 5" to run your suite in a pool of five threads.

If you're using ant, it's "suitethreadpoolsize".

I only have two tests for this so far so you might find a few bugs, let me know how it works for you.

Hi Cedric,

This is the feature that i have been trying to generate for myself. I was doing this using parallel ant tasks(Had sent a mail yesterday to which you had replied). Guess this will help me a lot... Thanks a ton. Will be testing it tomorrow in office will update you with its success as soon as i'm through with its results.

Thanks & Regards,

Hey Cedric,

Does this work only with jdk 1.6?  i tried with jdk 1.5 and got the following exception.

[testng] Exception in thread "main" java.lang.NoClassDefFoundError: java/io/Console

[testng]     at org.testng.TestNG.privateMain(TestNG.java:1083)

[testng]     at org.testng.TestNG.main(TestNG.java:1055)

[testng] The tests failed.

Regards,

Hi Anil,

Unfortunately, yes. It's because I added a dependency on a class in JCommander that I didn't realize was only available in the JDK 1.6. I have a potential solution but for now, please use JDK 1.6.

Sorry for the trouble.
