ANT – JUNIT – PARALLEL

Looking to speed up your builds by running your Junit tests in parallel with Ant?  With Ant 1.9.4, the Junit task now supports the “threads” attribute.  The default value is “1”, but can optionally be changed to the number of test threads desired that will be used for parallel test execution.

Note, when using this new attribute, you must set your “forkmode” equal to “perTest” and if you are upgrading to 1.10.x, Java 8 run-time is required.
