I am new to Rspec so i am not sure if this can be done. I want to
write a test that the outcome of a function is that a new file is
successfully created in a directory. The test would be somthing like
“it should save the xml to a file in /path/foo”.
Can this be done? If so how is it done? (I am guessing it would be a
clause in the “after” method.
