'''Test idlelib.textview.
|
|
|
|
Since all methods and functions create (or destroy) a TextViewer, which
|
|
is a widget containing multiple widgets, all tests must be gui tests.
|
|
Using mock Text would not change this. Other mocks are used to retrieve
|
|
information about calls.
|
|
|
|
Coverage: 94%.
