      "description": "update: Nested transforms should not affect the field mask, even\nwhen there are other values that do. Transforms should only affect the\nDocumentTransform_FieldTransform list.",
      "comment": "For updates, top-level paths in json-like map inputs\nare split on the dot. That is, an input {\"a.b.c\": 7} results in an update to\nfield c of object b of object a with value 7. In order to specify this behavior,\nthe update must use a fieldmask \"a.b.c\". However, fieldmasks are only used for\nconcrete values - transforms are separately encoded in a\nDocumentTransform_FieldTransform array.\n\nThis test exercises a bug found in python (https://github.com/googleapis/google-cloud-python/issues/7215)\nin which nested transforms ({\"a.c\": \"ServerTimestamp\"}) next to nested values\n({\"a.b\": 7}) incorrectly caused the fieldmask \"a\" to be set, which has the\neffect of wiping out all data in \"a\" other than what was specified in the\njson-like input.\n\nInstead, as this test specifies, transforms should not affect the fieldmask.",
