+'''Run human tests of Idle's window, dialog, and popup widgets.
+
+run(*tests)
+Create a master Tk window.  Within that, run each callable in tests
+after finding the matching test spec in this file.  If tests is empty,
+run an htest for each spec dict in this file after finding the matching
+callable in the module named in the spec.  Close the window to skip or
+end the test.
+
+In a tested module, let X be a global name bound to a callable (class
+or function) whose .__name__ attrubute is also X (the usual situation).
+The first parameter of X must be 'parent'.  When called, the parent
+argument will be the root window.  X must create a child Toplevel
+window (or subclass thereof).  The Toplevel may be a test widget or
+dialog, in which case the callable is the corresonding class.  Or the
+Toplevel may contain the widget to be tested or set up a context in
+which a test widget is invoked.  In this latter case, the callable is a
+wrapper function that sets up the Toplevel and other objects.  Wrapper
+function names, such as _editor_window', should start with '_'.
+
+
+End the module with
+
+if __name__ == '__main__':
+    <unittest, if there is one>
+    from idlelib.idle_test.htest import run
+    run(X)
+
+To have wrapper functions and test invocation code ignored by coveragepy
+reports, put '# htest #' on the def statement header line.
+
+def _wrapper(parent):  # htest #
+
+Also make sure that the 'if __name__' line matches the above.  Then have
+make sure that .coveragerc includes the following.
+
+[report]
+exclude_lines =
+    .*# htest #
+    if __name__ == .__main__.:
+
+(The "." instead of "'" is intentional and necessary.)
+
+
+To run any X, this file must contain a matching instance of the
+following template, with X.__name__ prepended to '_spec'.
+When all tests are run, the prefix is use to get X.
