-subdirectory should contain a test_xyz.py for each, where 'xyz' is lowercased
-even if xyz.py is not. Here is a possible template, with the blanks after after

 2. GUI Tests
 
-When run as part of the Python test suite, Idle gui tests need to run
-test.support.requires('gui') (test.test_support in 2.7).  A test is a gui test
-if it creates a Tk root or master object either directly or indirectly by
-instantiating a tkinter or idle class.  For the benefit of test processes that
-either have no graphical environment available or are not allowed to use it, gui
-tests must be 'guarded' by "requires('gui')" in a setUp function or method.

 3. Running Unit Tests
 
 Assume that xyz.py and test_xyz.py both end with a unittest.main() call.
-Running either from an Idle editor runs all tests in the test_xyz file with the
-version of Python running Idle.  Test output appears in the Shell window.  The
-'verbosity=2' option lists all test methods in the file, which is appropriate
-when developing tests. The 'exit=False' option is needed in xyx.py files when an
-htest follows.
