 {{{
 def test_ChunkedSampleFile(self):
         """
         ChunkedSampleFileList, ChunkedSampleFileDetail View Test
         """
         with TemporaryFile() as test_file:
             for count in range(100000):
                 test_file.write(('test_data %s' % count).encode())
             test_file.seek(0)
             hash_md5 = hashlib.md5()
             for chunk in iter(lambda: test_file.read(4096), b""):
                 hash_md5.update(chunk)
             etag = hash_md5.hexdigest()
             test_file.seek(0)

             #post
             response = self.client.post('%s/chunked_sample_files' %
 URL_PREFIX,
                         data={'file': test_file, 'name': 'test.vcf',
                               'sample_file_meta':

             self.assertEqual(response.status_code,
 status.HTTP_201_CREATED, response.content)
             file_id = response.json()['id']
