[New-bugs-announce] [issue30290] IDLE: add tests for help_about.py

[Terry J. Reedy]

New submission from Terry J. Reedy:

Initial plan.
1a. Change AboutDialog to mimic query.Query with respect to _utest and suppression of dialog display and waiting.
1b. Create AboutDialog instance.
2a. Change textview.TextViewer as with AboutDialog.  Also change textview functions and AboutDialog methods to pass on _utest.
2b. Simulate keyclicks on buttons and test that root gains appropriate child.  Then destroy it.
3. At some point, remove dead code and change now incorrect encoding comment.

Separate issue: add simulated button click tests to test_textview and other popup dialogs.  Directly calling commands does not test that buttons invoke the right command.
