SnowflakeCompare normalizes tolerance dict keys with
case_mode="upper", which turned the special"default"key into"DEFAULT".get_column_tolerancelooks up"default", which was then filled in as 0.0, so a dict like{"COL1": 0.1, "default": 0.5}silently compared every other column exactly. This skips upper casing for the"default"key and extendstest_case_sensitivityto cover it.Checks run:
