How to test a function that creates a directory?

Question

How to test a function in Python which creates a directory? Can you give an example make_directory_test() function?

def make_directory(directory):
    if not os.path.exists(directory):
        os.makedirs(directory)

Answer 1

Just test that directory exists

def test_make_directory(self):
    directory_path = '...' # somepath

    make_directory(directory_path)

    self.assertTrue(os.path.exists(directory_path))

And do ensure that any directories created in unit tests are deleted after each tests in tearDown or setUp, to ensure independency of tests
