-Writing new tests
-=================
-
-Precaution
-----------
-
-    New tests should always use only one Tk window at once, like all the
-    current tests do. This means that you have to destroy the current window
-    before creating another one, and clean up after the test. The motivation
-    behind this is that some tests may depend on having its window focused
-    while it is running to work properly, and it may be hard to force focus
-    on your window across platforms (right now only test_traversal at
-    test_ttk.test_widgets.NotebookTest depends on this).
