Pyfakefs not supporting os.renames?

Here's a simple piece of code I wanted to test:

import os

def move_all(firstPath, secondPath):
  for count, filename in enumerate(os.listdir(firstPath)):
    print('moving '+str(count) + '   '+filename)
    os.rename((firstPath+'\\'+filename),(secondPath+'\\'+filename))

def test_fakefs(fs):
  fakeDirectory = '\\fakeroot\\fakefolder'
  fakeFile1 = 'fake_file.txt'
  fakeFile2 = 'fake_file_2.txt'

  fs.create_dir(fakeDirectory)
  fs.create_file(fakeDirectory+"\\"+fakeFile1)
  fs.create_file(fakeDirectory+'\\'+fakeFile2)
  fs.create_dir(fakeDirectory+'2')

  move_all(fakeDirectory,(fakeDirectory+'2'))
  assert os.path.exists(fakeDirectory+'2\\fake_file.txt')

When running this using pytest, everything seems to work. However, if I switch 6th line to renames:

os.renames((firstPath+'\\'+filename),(secondPath+'\\'+filename))

I get

FileNotFoundError: [WinError 3] The system cannot find the path specified: '\fakeroot\fakefolder\fake_file.txt' -> '\fakeroot\fakefolder2\fake_file.txt'

Am I doing something wrong or does pyfakefs not support this os method? The very same function works as intended on a real file system.
