19-20: Consider adding parameter validation and documentationThe method signature looks good, but consider:
- Adding
@NotNullannotations for the parameters- Adding Javadoc to document the method's purpose, parameters, and possible exceptions
+ /** + * Retrieves exams assigned to a specific proctor within an organization. + * + * @param proctorId The ID of the proctor + * @param organizationId The ID of the organization + * @return List of exam responses + * @throws EntityNotFoundException if proctor or organization not found + */ + List<ExamResponse> getExamsForProctor(@NotNull Long proctorId, @NotNull Long organizationId);
24-24: Add validation and consider security implicationsFor the comment addition method:
- Add content length validation
- Consider adding a user/proctor parameter for audit purposes
- Consider returning a response object instead of void to confirm success
- void addCommentToCandidate(Long candidateId, Long examId, String content); + /** + * Adds a proctor's comment to a candidate's exam record. + * + * @param candidateId The ID of the candidate + * @param examId The ID of the exam + * @param content The comment content + * @param proctorId The ID of the proctor making the comment + * @return CommentResponse containing the created comment details + * @throws EntityNotFoundException if candidate or exam not found + * @throws ValidationException if content exceeds maximum length + */ + CommentResponse addCommentToCandidate( + @NotNull Long candidateId, + @NotNull Long examId, + @NotNull @Size(max = 1000) String content, + @NotNull Long proctorId + );src/main/java/com/testify/Testify_Backend/service/ExamSetterServiceImpl.java (2)
92-100: Optimize transaction management and simplify code using streams
- Add
readOnly = trueto the@Transactionalannotation to optimize performance for read-only operations.- Simplify the mapping from
List<Exam>toList<ExamResponse>using streams for cleaner code.Apply this diff:
@Override -@Transactional +@Transactional(readOnly = true) public List<ExamResponse> getExamsForProctor(Long proctorId, Long organizationId) { List<Exam> exams = examRepository.findByProctorIdAndOrganizationId(proctorId, organizationId); // Ensure repository method returns a List - List<ExamResponse> examResponses = new ArrayList<>(); - for (Exam exam : exams) { - examResponses.add(modelMapper.map(exam, ExamResponse.class)); - } + List<ExamResponse> examResponses = exams.stream() + .map(exam -> modelMapper.map(exam, ExamResponse.class)) + .collect(Collectors.toList()); return examResponses; }
104-112: Simplify collection mapping with streamsUse streams to convert
Set<Candidate>toSet<CandidateResponse>more concisely.Apply this diff:
@Override public Set<CandidateResponse> getCandidatesForExam(Long examId) { Set<Candidate> candidates = candidateRepository.findByExamId(examId); - Set<CandidateResponse> candidateResponses = new HashSet<>(); - for (Candidate candidate : candidates) { - candidateResponses.add(modelMapper.map(candidate, CandidateResponse.class)); - } + Set<CandidateResponse> candidateResponses = candidates.stream() + .map(candidate -> modelMapper.map(candidate, CandidateResponse.class)) + .collect(Collectors.toSet()); return candidateResponses; }src/main/java/com/testify/Testify_Backend/model/ProctorComment.java (2)
29-29: Enforce non-null constraint oncontentfieldAdd
@Column(nullable = false)to ensure that thecontentfield is not null in the database.Apply this diff:
+ @Column(nullable = false) private String content;
31-31: Automatically setcreatedAtusing@PrePersistUse the
@PrePersistannotation to automatically setcreatedAtbefore persisting.Add the following method to the class:
@PrePersist public void prePersist() { this.createdAt = LocalDateTime.now(); }src/main/java/com/testify/Testify_Backend/model/Candidate.java (1)
30-31: UseSetinstead ofListforcommentsto prevent duplicatesChange
commentsto aSetto avoid duplicate entries and improve performance.Apply this diff:
@OneToMany(mappedBy = "candidate", cascade = CascadeType.ALL, orphanRemoval = true) - private List<ProctorComment> comments; + private Set<ProctorComment> comments;Don't forget to import
java.util.Set.src/main/java/com/testify/Testify_Backend/repository/CandidateRepository.java (1)
27-28: Simplify repository method using derived queryReplace the custom
@Querywith a derived query method provided by Spring Data JPA.Apply this diff:
- @Query("SELECT c FROM Candidate c JOIN c.exams e WHERE e.id = :examId") - Set<Candidate> findByExamId(@Param("examId") Long examId); + Set<Candidate> findAllByExamsId(Long examId);src/main/java/com/testify/Testify_Backend/controller/ExamSetterController.java (1)
Line range hint
48-75: Add API documentation.Consider adding OpenAPI/Swagger annotations to document the new endpoints, their parameters, request/response models, and possible error scenarios.
Example for one endpoint:
@Operation(summary = "Get exams for proctor", description = "Retrieves all exams assigned to a proctor in an organization") @ApiResponses(value = { @ApiResponse(responseCode = "200", description = "Successfully retrieved exams"), @ApiResponse(responseCode = "400", description = "Invalid proctor or organization ID"), @ApiResponse(responseCode = "404", description = "Proctor or organization not found") }) @GetMapping("/proctor/{proctorId}/{organizationId}") public ResponseEntity<List<ExamResponse>> getExamsForProctor( @Parameter(description = "ID of the proctor") @PathVariable Long proctorId, @Parameter(description = "ID of the organization") @PathVariable Long organizationId ) { // ... existing code ... }

4-5: LGTM! Import statements are appropriate
The new imports align with the response types used in the added method signatures.
21-23: Consider using consistent collection types
The interface uses both List and Set for collections. Consider standardizing to one type unless there's a specific reason for the difference.
src/main/java/com/testify/Testify_Backend/repository/ExamRepository.java (1)
35-36: Validate the necessity of custom query
Ensure that the custom @Query is necessary and cannot be replaced with a derived query for maintainability.
Since you are joining on a collection, the custom query might be required. If possible, consider a derived query like findByProctorsIdAndOrganizationId(Long proctorId, Long organizationId).

27-27: 🛠️ Refactor suggestion
Remove unused service dependency.
The examManagementService field appears to be unused in the controller. Either remove it or document its intended use.

Enhance exception handling and transaction management
- Annotate the method with
@Transactionalto ensure atomicity of database operations. - Replace generic
RuntimeExceptionwith more specific exceptions likeEntityNotFoundExceptionfor clearer error handling.
Apply this diff:
+@Transactional
public void addCommentToCandidate(Long candidateId, Long examId, String content) {
Candidate candidate = candidateRepository.findById(candidateId)
- .orElseThrow(() -> new RuntimeException("Candidate not found"));
+ .orElseThrow(() -> new EntityNotFoundException("Candidate not found with id: " + candidateId));
Exam exam = examRepository.findById(examId)
- .orElseThrow(() -> new RuntimeException("Exam not found"));
+ .orElseThrow(() -> new EntityNotFoundException("Exam not found with id: " + examId));
ProctorComment comment = new ProctorComment();
comment.setCandidate(candidate);
comment.setExam(exam);
comment.setContent(content);
comment.setCreatedAt(LocalDateTime.now());
proctorCommentRepository.save(comment);
}Ensure to import jakarta.persistence.EntityNotFoundException or define a custom exception class if appropriate.

🛠️ Refactor suggestion
Consider initializing the List and managing JSON serialization.
While the relationship mapping is correct, consider these improvements:
- Initialize the List to prevent potential NPEs
- Add @JsonIgnore to prevent infinite recursion during serialization
- Add a helper method to manage the bidirectional relationship
Apply this diff:
@OneToMany(mappedBy = "exam", cascade = CascadeType.ALL, orphanRemoval = true)
+ @JsonIgnore
- private List<ProctorComment> proctorComments;
+ private List<ProctorComment> proctorComments = new ArrayList<>();

🛠️ Refactor suggestion
Enhance POST endpoint with proper request mapping and validation.
The endpoint needs:
- Proper @RequestBody mapping with a DTO
- Content-Type specification
- Input validation
- Better error handling
Apply these improvements:
@PostMapping("/{candidateId}/{examId}/proctorComments")
+ @Consumes(MediaType.APPLICATION_JSON_VALUE)
- public ResponseEntity<String> addComment(@PathVariable Long candidateId, @PathVariable Long examId, @RequestBody String content) {
+ public ResponseEntity<String> addComment(
+ @PathVariable Long candidateId,
+ @PathVariable Long examId,
+ @Valid @RequestBody ProctorCommentRequest request
+ ) {
+ if (candidateId == null || candidateId <= 0 || examId == null || examId <= 0) {
+ return ResponseEntity.badRequest().body("Invalid candidate or exam ID");
+ }
+ if (request.getContent() == null || request.getContent().trim().isEmpty()) {
+ return ResponseEntity.badRequest().body("Comment content cannot be empty");
+ }
- examSetterService.addCommentToCandidate(candidateId, examId, content);
+ examSetterService.addCommentToCandidate(candidateId, examId, request.getContent());
return ResponseEntity.ok("Comment added successfully");
}Create a new DTO:
@Data
public class ProctorCommentRequest {
@NotBlank(message = "Comment content is required")
private String content;
}| @GetMapping("/proctor/{proctorId}/{organizationId}") | ||
| public ResponseEntity<List<ExamResponse>> getExamsForProctor(@PathVariable Long proctorId, @PathVariable Long organizationId) { | ||
| List<ExamResponse> exams = examSetterService.getExamsForProctor(proctorId, organizationId); | ||
| return ResponseEntity.ok(exams); | ||
| } |

🛠️ Refactor suggestion
Add input validation and error handling.
The endpoint needs validation for:
- Non-null and positive IDs
- Existence of proctor and organization
- Proctor's association with the organization
Add validation and error handling:
@GetMapping("/proctor/{proctorId}/{organizationId}")
public ResponseEntity<List<ExamResponse>> getExamsForProctor(@PathVariable Long proctorId, @PathVariable Long organizationId) {
+ if (proctorId == null || proctorId <= 0 || organizationId == null || organizationId <= 0) {
+ return ResponseEntity.badRequest().build();
+ }
List<ExamResponse> exams = examSetterService.getExamsForProctor(proctorId, organizationId);
return ResponseEntity.ok(exams);
