We are using DevTest 8.3. In order to run cases from build job, we are using junitlisa Ant task to run the cases in mar file. The overall running time is over 1.5 hours. We wanted to shorten the running time. I tried to set the run mode in test suite as concurrent and ran the test suite locally in DevTest workstation. The overall running time is half. However when I built the mar file with the test suite (concurrent mode) and ran with junitlisa Ant task, the cases were run in sequence mode. The concurrent mode setting did not work. Could anyone advise me how to set the concurrent mode in mar file so that the cases can be run concurrently when triggered with junitlisa Ant task. Thanks.
