Why does my mockito failed test when actual result same as the expected result? flutter - flutter

Question

I'm using Mockito in flutter application and want to add some test cases:
this run failed while the actual result is the same as expected result, here's my test file:
#GenerateMocks([ResumeParserDataSource])
void main() {
late MockResumeParserDataSource resumeParserDataSource;
late ResumeParserController resumeParserController;
late ResumeParserRepo resumeParserRepo;
setUp(() async {
Get.reset();
resumeParserDataSource = MockResumeParserDataSource();
resumeParserRepo =
Get.put(ResumeParserRepo(dataSource: resumeParserDataSource));
resumeParserController = Get.put(ResumeParserController());
});
group('Upload resume that uploaded into API:\n', () {
test(
'~succeed state~ api get response and parsed it into model JSON "ParsedDetailsResume"',
() async {
when(resumeParserRepo
.getResumeDetailsAfterParsing(ResumeParserTestUtil.fileName))
.thenAnswer((_) async => Right(
ResumeParserTestUtil.parsedResumeDetailsFunction(
ResumeParserTestUtil.parsedResumeDetailsModel1)));
await resumeParserController
.parseResumeToAPI(ResumeParserTestUtil.fileName);
await waitForAPIResponse();
expect(
resumeParserController.parsedResume.value,
some(ResumeParserTestUtil.parsedResumeDetailsFunction(
ResumeParserTestUtil.parsedResumeDetailsModel1)));
expect(resumeParserController.error.value, none());
});
});
}
here's my ResumeParserController:
class ResumeParserController extends GetxController {
static ResumeParserController get to => Get.find();
final resumeParserRepo = ResumeParserRepo.to;
Rx<Option<ParsedResumeDetails>> parsedResume =
Rx<Option<ParsedResumeDetails>>(none());
Future<Either<DioError, ParsedResumeDetails>> parseResumeToAPI(
String fileName,
{User? user}) async {
var result = await resumeParserRepo.getResumeDetailsAfterParsing(
fileName,
user: user,
);
return result.fold(
(l) => Left(l),
(newParsedResume) async {
error.value = none();
parsedResume.value = some(newParsedResume);
update();
return Right(newParsedResume);
},
);
}
}
and here's my json model in ResumeParserTestUtil:
class ResumeParserTestUtil {
static String fileName = "12989801ahsduiabsdui9123ajd.pdf";
static ParsedResumeDetails parsedResumeDetailsFunction(
Map<String, dynamic> response,
{User? user}) {
var userSkills = response['data']['userSkills'] == null
? [PublicUserSkill.empty()]
: List.from(response['data']['userSkills'])
.map((e) => PublicUserSkill.fromJson(e["skill"]))
.toList();
var userEducations = response['data']['educations'] == null
? [EducationParsed.empty()]
: List.from(response['data']['educations'])
.map((e) => EducationParsed.fromJson(e))
.toList();
var experiences = response['data']['experiences'] == null
? [ExperiencesParsed.empty()]
: List.from(response['data']['experiences'])
.map((e) => ExperiencesParsed.fromJson(e))
.toList();
return ParsedResumeDetails(
user: user,
userSkills:
userSkills.map(mapPublicUserSkillToSkillWithUserSkill).toList(),
userEducation: userEducations,
userWorkExperience: experiences,
);
}
static Map<String, dynamic> parsedResumeDetailsModel1 = {

"state": null,

}
}
]
}
};
}
and this was the result:
Expected: Some:<Some(ParsedResumeDetails([EducationParsed(true, null, null, null, EDUCATION), EducationParsed(true, null, null, null, EDUCATION), EducationParsed(true, null, null, null, EDUCATION)], [ExperiencesParsed(false, null, Unnamed company, null, WORK)], [Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill'], null))>
Actual: Some:<Some(ParsedResumeDetails([EducationParsed(true, null, null, null, EDUCATION), EducationParsed(true, null, null, null, EDUCATION), EducationParsed(true, null, null, null, EDUCATION)], [ExperiencesParsed(false, null, Unnamed company, null, WORK)], [Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill', Instance of 'SkillWithUserSkill'], null))>

Any thoughts on this? Thanks!

Ran into same issue trying test async call, where it was failing because I set expected value wrapped in a Future.value()
Solution in this case is to :
extract the value from the async call first with await
then do the check on raw value, without any notion of Future<>
eg:
test('test SomeService()', () async {
final actual = await someService.getSomeList();
expect(actual, []);
});
