E.g., I wrote some data to the file and then try to read them:
mocked_open = mock_open()
with patch('__builtin__.open', mocked_open, create=True):
with open('file', 'w') as f:
f.write('text')
with open('file', 'r') as f:
res = f.read()
But after this,res
is empty. How to get written data for this file?
