One can start with a set rather than tuple of file names.

     def test_1(self):
         "Verify creation of files is possible"
         filenames = {"this.txt", "that.txt", "the_other.txt"}
         for filename in filenames:
             f = open(filename, "w")
             f.write("Some text\n")
             f.close()
             self.assertTrue(f.closed)
         dir_names = set(os.listdir())
         self.assertEqual(dir_names, filenames)
