|   | 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). | ||
