tests.  One difficulty when testing software is that the code under test might
need to read or write to files in the local file system.  If the file system
is not set up in just the right way, it might cause a spurious error during
the test.  The pyfakefs library provides a solution to problems like this by
mocking file system interactions.  In other words, it arranges for the code
under test to interact with a fake file system instead of the real file
system.  The code under test requires no modification to work with pyfakefs.")
