Before testing, let alone documenting, the status quo, I would like to be sure
that suppressing the exception is truly the intended behavior. Is there a way
to get an annotated listing from git (given which patch, and therefore which
person, is responsible for each line)? I will try asking on pydev.
Calling __getattr__ on property failure is a behavior of __getattribute__, not
of the property, and I would expect object.__getattribute__ to be tested
wherever object is, but I have not found such tests. If we do add a test, the
best model in test_desc.py looks like `def test_module_subclasses(self):`. The
test class would only need __getattr__ and the faulty property.
class Foo(object):
def __getattr__(self, name):
print(f'Getattr {name}')
return True
@property
def bing(self):
print('Property bing')
raise AttributeError("blarg")
f = Foo()
print(f.bing)
#prints (which would be the log list in a test)
Property bing
Getattr bing
True
