"""Run human tests of Idle's window, dialog, and popup widgets.
run(*tests) Create a master Tk() htest 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 master window to end testing.
In a tested module, let X be a global name bound to a callable (class or
function) whose .__name__ attribute is also X (the usual situation). The
first parameter of X must be 'parent' or 'master'. When called, the
first argument will be the root window. X must create a child
Toplevel(parent/master) (or subclass thereof). The Toplevel may be a
test widget or dialog, in which case the callable is the corresponding
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 '_' and be lowercase.
End the module with
if __name__ == '__main__':
<run unittest.main with 'exit=False'>
from idlelib.idle_test.htest import run
run(callable) # There could be multiple comma-separated callables.
To have wrapper functions ignored by coverage reports, tag the def
header like so: "def _wrapper(parent): # htest #". Use the same tag
for htest lines in widget code. 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.
