JBoss JRunit is a project to aid in adding benchmarking to JUnit based test cases as well as providing a       framework extension to JUnit to allow for distributed client/server based tests.       It is important to note that JBoss JRunit is not a replacement for the popular test framework JUnit,       but an extention to it allowing for more enterprise focused features.
