| 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). |
