For what it is worth, rewriting the code in this way already helped me to identify a mistake: ```python def test_sort(self): selector = {"location": {"$beginsWith": "A"}} cases = [ { "sort": ["location"], "start_key": [b"A"], "end_key": [b"A\xef\xbf\xbd", b"<MAX>"], "direction": "fwd", }, { "sort": [{"location": "desc"}], "start_key": [b"A\xef\xbf\xbd", b"<MAX>"], "end_key": [b"A"], "direction": "rev", }, ] for case in cases: with self.subTest(sort=case["sort"]): mrargs = self.get_mrargs(selector, sort=case["sort"]) self.assertEqual(to_utf8_bytes(mrargs["start_key"]), case["start_key"]) self.assertEqual(to_utf8_bytes(mrargs["end_key"]), case["end_key"]) self.assertEqual(mrargs["direction"], case["direction"]) ``` -- This is an automated message from the Apache Git Service.
