   6 test_description='test git clone to cleanup after failure
   7
   8 This test covers the fact that if git clone fails, it should remove
   9 the directory it created, to avoid the user having to manually
  10 remove the directory before attempting a clone again.
  11
  12 Unless the directory already exists, in which case we clean up only what we
  13 wrote.
