# Python 3 specific tests, like the one in coverage/classes.py
|
|
#
|
|
# User-defined methods, both instance methods and class methods, can be called in many non-standard ways
|
|
# i.e. differently from simply `c.f()` or `C.f()`. For example, a user-defined `__await__` method on a
|
|
# class `C` will be called by the syntactic construct `await c` when `c` is an instance of `C`.
|
|
#
|
|
# These tests should cover all the class calls that we hope to support.
|
|
# It is based on https://docs.python.org/3/reference/datamodel.html, and headings refer there.
|
|
#
|
|
# All functions starting with "test_" should run and execute `print("OK")` exactly once.
|
|
# This can be checked by running validTest.py.
