"""Test query, coverage 91%).
Non-gui tests for Query, SectionName, ModuleName, and HelpSource use
dummy versions that extract the non-gui methods and add other needed
attributes. GUI tests create an instance of each class and simulate
entries and button clicks. Subclass tests only target the new code in
the subclass definition.
The appearance of the widgets is checked by the Query and
HelpSource htests. These are run by running query.py.
