New submission from Damien Nadé <bugzilla-pyt...@livna.org>:
While we can iterate on a mock_open handle, it is not actually possible to
perform a next() on it.
My use case is the following: I have a file with a one-line header that I want
to skip. So, roughly, my code is like
with open(filename, 'r') as my_file:
confirm_header(next(my_file))
for line in my_file:
do_something(line)
And while writing a unit test on this code, the handle returned by
mock_open(read_data=my_read_data) returns a mock instead of the first line of
my_read_data.
