Maven surefire plugin not setting -suitethreadpoolsize parameter for parallel suites execution.

[sjavvadi]

Currently latest surefire plugin (version 2.17) is using deprecated TestNG configure (Map) method in which Map argument is converted to CommandLineArgs. Unfortunately the suitethreadpoolsize parameter is missing and CommandLineArgs.SUITE_THREAD_POOL_SIZE is not set and not executed.

The following fragment of code placed in org.testng.TestNG.java in method configure(Map cmdLineArgs) will resolve this issue:

Object suiteThreadPoolSize = cmdLineArgs.get(CommandLineArgs.SUITE_THREAD_POOL_SIZE);
if (null != suiteThreadPoolSize) {
if (suiteThreadPoolSize instanceof String){
result.suiteThreadPoolSize=Integer.parseInt((String) suiteThreadPoolSize);
}
if (suiteThreadPoolSize instanceof Integer){
result.suiteThreadPoolSize=(Integer) suiteThreadPoolSize;
}
}
