6-7: Add@NoArgsConstructorfor better deserialization support.Including the
@NoArgsConstructorannotation ensures that a no-argument constructor is generated, which is essential for frameworks like Jackson during object deserialization.Add the annotation as shown:
@Data @AllArgsConstructor +@NoArgsConstructor public class CandidateExamDetailsDTO { // class body }src/main/java/com/testify/Testify_Backend/service/GradingServiceImpl.java (1)
5-5: Remove unused importThe
CandidateExamDetailsDTOimport appears to be unused in this class.src/main/java/com/testify/Testify_Backend/service/CandidateServiceImpl.java (1)
236-261: Consider adding pagination supportThe method retrieves all exam details without pagination, which could lead to performance issues with large datasets.
Consider adding pagination support:
- Update the repository method to return a Page
- Add pagination parameters to the method signature
- Return a paginated response
Would you like me to provide an example implementation with pagination support?

1131-1134: Updated response includes necessary exam and session details.
The inclusion of examTitle, examType, sessionId, and endTime in the CandidateExamAnswerResponse enhances the response by providing clients with essential exam and session information.
src/main/java/com/testify/Testify_Backend/responses/exam_management/CandidateExamAnswerResponse.java (1)
14-17: Enhancement: Include additional exam and session details in the response.
Adding examName, examType, sessionId, and endTime to CandidateExamAnswerResponse provides clients with comprehensive information about the exam and session, improving the context and usability of the data returned.
src/main/java/com/testify/Testify_Backend/service/CandidateService.java (1)
22-22: Addition of method to retrieve candidate exam details.
Introducing getCandidateExamDetails(String candidateId) in the CandidateService interface appropriately extends the service's capabilities to fetch exam details specific to a candidate.

236-261: Verify access control implementation
Let's verify if proper access controls are implemented across the codebase for exam details access.

🛠️ Refactor suggestion
Consider changing 'score' field to a numeric data type.
Since score represents a numeric value, it would be more appropriate to use a numeric data type such as double or BigDecimal instead of String. This change will facilitate numerical operations and comparisons.
Apply this diff to update the data type:
public class CandidateExamDetailsDTO {
private String grade;
- private String score;
+ private double score;
private String examName;
private String organizationName;

Correct method name to follow Java naming conventions.
The method name findByCandidateID should be updated to findByCandidateId to adhere to standard Java naming conventions and ensure consistency with entity field naming.
Apply this diff to correct the method name:
public interface ExamCandidateGradeRepository extends JpaRepository<ExamCandidateGrade, String> {
- List<ExamCandidateGrade> findByCandidateID(String candidateId);
+ List<ExamCandidateGrade> findByCandidateId(String candidateId);

Add security checks and error handling
The endpoint needs additional security measures and error handling:
- Add authentication/authorization checks using
@PreAuthorize - Wrap response in
ResponseEntityto handle different HTTP status codes - Add exception handling for invalid IDs or service errors
Consider refactoring to:
-@GetMapping("/{id}/exam-details")
-public List<CandidateExamDetailsDTO> getCandidateExamDetails(@PathVariable String id) {
- return candidateService.getCandidateExamDetails(id);
-}
+@GetMapping("/{id}/exam-details")

🛠️ Refactor suggestion
Add input validation and improve error handling
The method implementation has several areas for improvement:
- Missing input validation for candidateId
- Potential NPE in the stream when handling null values
- Inefficient Optional handling
- Missing logging for debugging purposes
Consider refactoring to:
@Override
@Transactional
public List<CandidateExamDetailsDTO> getCandidateExamDetails(String candidateId) {
+ if (candidateId == null || candidateId.trim().isEmpty()) {
+ throw new IllegalArgumentException("Candidate ID cannot be null or empty");
+ }
+
+ log.debug("Fetching exam details for candidate: {}", candidateId);
+
// Retrieve all grade details for the candidate
List<ExamCandidateGrade> grades = examCandidateGradeRepository.findByCandidateID(candidateId);
// Map the results to CandidateExamDetailsDTO
return grades.stream()
+ .filter(Objects::nonNull)
.map(candidateGrade -> {
- Optional<Exam> examOptional = examRepository.findById(Long.valueOf(candidateGrade.getExamID()));
-
- if (examOptional.isPresent()) {
- Exam exam = examOptional.get();
+ try {
+ Exam exam = examRepository.findById(Long.valueOf(candidateGrade.getExamID()))
+ .orElseThrow(() -> new EntityNotFoundException("Exam not found: " + candidateGrade.getExamID()));
+
Organization organization = exam.getOrganization();
-
+ String orgName = Optional.ofNullable(organization)
+ .map(Organization::getFirstName)
+ .orElse("No Organization");
+
// Return the data in the DTO format
return new CandidateExamDetailsDTO(
candidateGrade.getGrade(),
candidateGrade.getScore(),
exam.getTitle(),
- organization != null ? organization.getFirstName() : "No Organization"
+ orgName
);
+ } catch (Exception e) {
+ log.error("Error processing exam details for grade: {}", candidateGrade.getExamID(), e);
+ return null;
}
-
- return null; // Or handle cases where the exam is not found
