Bug report
Bug description:
from dataclasses import dataclass
from unittest.mock import create_autospec
@dataclass
class Description:
name: str
mock = create_autospec(Description, instance=True)
print(isinstance(mock, Description))# 3.13.3
True
# 3.14.0b2
False
Furthermore the resulting mock doesn't have attributes present on a dataclass instance, like __annotations__, __class__, __dataclass_fields__, __dataclass_params__.
print(dir(mock))
print(dir(Description("Hello World"))Likely related to #124429. /CC @sobolevn
