   Running the tests over up to date build on Ubuntu 16.04 64-bit.

   ./python -m test.test_ttk_guionly -v

   Sometimes this runs without failure and sometimes it 'hangs' and then produces failures. When it hangs, my computer freezes completely. As you can see, it can run for 8 minutes.

   It seems to hang most often on test_idenify in EntryTest.

   Here's one set of failures:

   bpo-40722 is about a hang, at least once, on line 147

       def test_variable_change(self):

           x.pack()
           x.wait_visibility()  # Here.

    These failures are all fixed by the test hardening in gh-69134 (#152499, backported to 3.13/3.14/3.15).

    The named tests no longer assert on unmapped geometry or block on wait_visibility(); they now wait for the window manager to map the widget (or skip cleanly):

    • EntryTest.test_identify ('' != 'textarea') and ScaleTest.test_get/test_set now guard the geometry assertions with wait_until_mapped().
    • The LabeledScale hang at wait_visibility() (bpo-40722) is gone — that test uses require_mapped() instead, which never blocks indefinitely.

    Closing as completed.
