ng lint failed because autocomplete-dropdown.e2e.ts has object properties that don't follow the naming conventions of ["camelCase", "snake_case", "UPPER_CASE", "PascalCase"].

In my local branch, I added a filter to pass ng lint.

        "@typescript-eslint/naming-convention": [
          "error",
          {
            "selector": "default",
            "format": ["camelCase", "snake_case", "UPPER_CASE", "PascalCase"],
            "leadingUnderscore": "allowSingleOrDouble",
            "trailingUnderscore": "allow",
            "filter": {
              "regex": "(should)|@tags",
              "match": false
            }
          },
        ]

Is it correct?
