To guard a test class, put "requires('gui')" in its setUpClass function.
-To avoid interfering with other GUI tests, all GUI objects must be
-destroyed and deleted by the end of the test. Widgets, such as a Tk
-root, created in a setUpX function, should be destroyed in the
-corresponding tearDownX. Module and class widget attributes should also
-be deleted.
+To avoid interfering with other gui tests, all gui objects must be destroyed and
+deleted by the end of the test. The Tk root created in a setUpX function should
+be destroyed in the corresponding tearDownX and the module or class attribute
+deleted. Others widgets should descend from the single root and the attributes
+deleted BEFORE root is destroyed. See https://bugs.python.org/issue20567.

Requires('gui') causes the test(s) it guards to be skipped if any of
-a few conditions are met:
-
+these conditions are met:
+
- The tests are being run by regrtest.py, and it was started without
enabling the "gui" resource with the "-u" command line option.
-
+
- The tests are being run on Windows by a service that is not allowed
to interact with the graphical environment.
-
+
+ - The tests are being run on Linux and X Windows is not available.
+
- The tests are being run on Mac OSX in a process that cannot make a
window manager connection.
-
+
- tkinter.Tk cannot be successfully instantiated for some reason.
-
+
- test.support.use_resources has been set by something other than
regrtest.py and does not contain "gui".
-

Tests of non-GUI operations should avoid creating tk widgets. Incidental
uses of tk variables and messageboxes can be replaced by the mock
classes in idle_test/mock_tk.py. The mock text handles some uses of the
