This plugin enables you to track and the executiontimes of a selection of Your unittests (JUnit or TestNG). One usage is to regard some of your automatic testcases as performancetests, tracking their executiontimes. Another usage is simply to monitor Your automatic tests to discover reasons for slow build times.

The newest version!
