[jbossws-dev] Parallel / concurrent testsuite execution

Folks, I've just solved JBWS-3482. That basically allows running multiple tests at the same time leveraging the Maven integration with JUnit 4. The surefire plugin is currently configured with <parallel>classes</parallel> <threadCount>1</threadCount> <perCoreThreadCount>true</perCoreThreadCount> meaning we have one thread per core (not that much to keep memory consumption low) and all test methods of a testcase class are execute in the same thread. My local testing on a Core i7 M620 @2.67GHz shows a 38% improve in time taken to run the full jbossws-cxf testsuite (compared actual testcases executions using -o -Dnoprepare=true). I've been fixing the RemoteDeployer classes to allow concurrent invocations to deploy()/undeploy()/etc. and the testsuites to avoid trying deploying archives containing endpoints with the same context-root (which would cause exceptions in the web layer). So starting from now, please be careful with that (most the time this basically means using unique names for test archives). While the concurrent runs are enabled by default and I've had very consistent good results, you can now also try the experimental maven concurrent execution mode with the jbossws testsuites. That is enabled by using the -T maven option, e.g.: 'mvn -T2 -Pjboss712 -Djboss712.home=/path/to/jboss-as-7.1.2.Final-SNAPSHOT integration-test' Use this with the testsuite only, not when building/installing the stack. Speaking of performances, I've noticed an additional 17% execution time improvement with -T2. Cheers Alessio -- Alessio Soldano Web Service Lead, JBoss
