| 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). | |
