Why we need to recheck getattr after dir?

[Tusenka]

What is the purpose of this line?


I've read - this issue but still don't quit understand in which cases a property from dir could invoke AttributeError for getattr.
Are there any examples and/or tests for this issue?

Sometimes magicmock instances look like fixtures

However this condition existed before the fixture function definition

We should experiment if the check is still needed
