%X The testing of systems using tools such as JUnit is well
   known to the
sequential programming community. It is
   perhaps less well known to the parallel
computing community
   because it relies on systems terminating so that
   system
outputs can be compared with expected outputs. A
   highly parallel architecture is
described that allows the
   JUnit testing of non\-terminating MIMD process
   based
parallel systems. The architecture is then extended
   to permit the sampling of a
continuously running system. It
   is shown that this can be achieved using a small
number of
   additional components that can be easily modified to suit a
   particular
sampling situation. The system architectures are
   presented using a Groovy
implementation of the JCSP and
   JUnit packages.
