cpython/Lib/idlelib/idle_test/htest.py

'''Run human tests of Idle's window, dialog, and popup widgets.

run(*tests)
Run each callable in tests after finding the matching test spec in this file.
If there are none, run an htest for each spec dict in this file after finding
the matching callable in the module named in the spec.

In a tested module, let X be a global name bound to a widget callable.
End the module with

if __name__ == '__main__':
    <unittest, if there is one>
    from idlelib.idle_test.htest import run
    run(X)

The X object must have a .__name__ attribute and a 'parent' parameter.
X will often be a widget class, but a callable instance with .__name__
or a wrapper function also work. The name of wrapper functions, like
'_editor_window', should start with '_'.

This file must contain a matching instance of the following template,
with X.__name__ prepended, as in '_editor_window_spec ...'.

_spec = {
    'file': '',
    'kwds': {'title': ''},
    'msg': ""
    }

file (no .py): used in run() to import the file and get X.
kwds: passed to X (**kwds), after 'parent' is added, to initialize X.
title: an example; used for some widgets, delete if not.
msg: displayed in a master window. Hints as to how the user might
  test the widget. Close the window to skip or end the test.

Modules not being tested at the moment:
PyShell.PyShellEditorWindow
Debugger.Debugger
AutoCompleteWindow.AutoCompleteWindow
OutputWindow.OutputWindow (indirectly being tested with grep test)
