+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).
