If the list includes `flow`, then `babel-flow` is included implicitly. If the list includes `babel`, and the current directory is inside `tests/format/js` or `tests/format/jsx`, then `acorn`, `espree`, and `meriyah` are included implicitly.
 - **`options`**: In addition to Prettier's formatting options, can contain the `errors` property to specify that it's expected that the formatting shouldn't be successful and an error should be thrown for all (`errors: true`) or some combinations of input entries and parsers.
