# FileSystemDjangoTestCase (New in 1.3.0)

FileSystemDjangoTestCase has a tear down method to delete all test files generated by tests, to avoid letting trash in the file system:

    class MyTests(FileSystemDjangoTestCase):
        def test_x(self):
            print(dir(self))

It also has a collection of methods to simplify tests that use files, like:

- create_temp_directory

- remove_temp_directory

- create_temp_file

- create_temp_file_with_name

- rename_temp_file

- remove_temp_file

- copy_file_to_dir

- add_text_to_file

- get_directory_of_the_file

- get_filename

- get_filepath

- get_content_of_file

- create_django_file_with_temp_file

- create_django_file_using_file

It also contains a set of assertion methods:

- assertFileExists

- assertFileDoesNotExists

- assertDirectoryExists

- assertDirectoryDoesNotExists

- assertDirectoryContainsFile

- assertDirectoryDoesNotContainsFile

- assertFilesHaveEqualLastModificationTimestamps

- assertFilesHaveNotEqualLastModificationTimestamps

- assertNumberOfFiles
