#2222: Testsuite code should remove output directories before tests
---------------------------------+--------------------
 Reporter:  Roland Haas          |       Type:  defect
   Status:  new                  |   Priority:  major
Milestone:                       |  Component:  Cactus
  Version:  development version  |   Keywords:
---------------------------------+--------------------
 The current testsuite driver code does not remove output directories ins
 TEST/sim/THORN which can hide issues if a new revision of the code simply
 no longer produces an output file if an older test is still present.

 There is also one test (Hydro_RNSID/rnsA2.par) that internally writes and
 reads data to a file while it runs. If the file is already present, then
 not all code is tested.

 To test this, place a new file into an output directory, run the tests and
 the file will still be present.
