New submission from Jesús Cea Avión:
mock_open(read_data=b'...') gives an error:
"""Traceback (most recent call last):
File "z.py", line 6, in <module>
print(f.read())
File "/usr/local/lib/python3.4/unittest/mock.py", line 896, in __call__

"""
Easy to reproduce:
"""
from unittest.mock import mock_open, patch
m = mock_open(read_data= b'abc')
with patch('__main__.open', m, create=True) :
with open('abc', 'rb') as f :
print(f.read())
"""
Looks like this bug was introduced as result of issue #17467. I add those
people to the nosy list.
