Multiple test functions are trying to open a steganogrified file and failing because another test deleted it.
The functions that share this file are
test_main_hide_file_no_output
test_main_hide_msg_no_output
A copy of the clean png file can be used and renamed at the beginning of the function. Alternatively this may have been solved another way. This problem has appeared before with files being deleted by another function before it is read.
