   # IMPORTANT: If you plan to deactivate / comment out a test please write a bug number to the commented out line of code.
   #
   #     Example: #mitkMyTest #this test is commented out because of bug 12345
   #
   # It is important that the bug is open and that the test will be activated again before the bug is closed. This assures that
   # no test is forgotten after it was commented out. If there is no bug for your current problem, please add a new one and
   # mark it as critical.
