How can test if data has been written into a json successfully in Flutter and Dart?

I'm not entirely sure what you mean but I think you want to make sure that your deserialization works, right?
void main (){
late Map<String,dynamic> json;
setUp(() {
json = {
id : yourIDData,
createdAt : yourDateData,
defaultLanguage : yourLanguageData,
defaultSchool : yourSchoolData,
};
});
test('object has correct properties', () {
final userData = UserData.fromJson(json);
expect(userData.id, yourIDData);
expect(userData.createdAt, yourDateData);
expect(userData.defaultLanguage, yourLanguageData);
expect(userData.defaultSchool, yourSchoolData);
});
}

I want to write a test for a user_data dart file. I want to check if data has been successfully written into the json file through an effective test.
@JsonSerializable() class UserData { UserData({ this.id, this.createdAt, this.defaultLanguage, this.defaultSchool, }); factory UserData.fromJson(Map<String, dynamic> json) => _$UserDataFromJson(json); final String? id; final DateTime? createdAt; final String? defaultLanguage; final School? defaultSchool; }
Can anyone help to generate a unit test for the above dart code? Thank you!

Annie Box over 1 yearYes, I want to ensure that my serialization and deserialization work well. Should I parse JSON to a model and test it? I try the code you shared, it seems doesn't work. Could you please give it a look and see if there is any error or bug? Thanks!
