Feature: New Duplicates Module

[jasonsiders]

Closes #150

This PR introduces a new Duplicates module to the apex-database-layer repository. The module is designed to provide enhanced support for detecting and managing duplicate records within the database abstraction layer.

Key Features

• Detection Utilities: Functions to identify duplicate records based on customizable criteria.
• Resolution Methods: Options for resolving duplicates, such as merging or deleting records.
• Configurable Matching: Ability to specify which fields should be used to determine duplication.
• Performance Optimizations: Efficient algorithms to minimize overhead when scanning large datasets.

Implementation Details

• Adds comprehensive unit tests to ensure module reliability.
• Module is extensible for future enhancements (e.g., custom duplicate handling strategies).
• Documentation and usage examples included.

Impact

This feature will help improve data integrity and streamline duplicate management processes for applications using the apex-database-layer.

PR Review: Feature - New Duplicates Module

I've completed a comprehensive review of this PR focusing on code quality, potential bugs, performance considerations, security concerns, and test coverage.

Review Checklist:

• Analyze core implementation files (Duplicates.cls, MockDuplicates.cls)
• Review test coverage and quality
• Check integration with existing codebase
• Examine performance implications
• Identify security concerns
• Review architectural decisions
• Provide detailed feedback and recommendations

---

Summary

This is a high-quality implementation that adds comprehensive duplicate detection capabilities to the Apex Database Layer. The module follows established patterns perfectly and maintains consistency with the existing codebase architecture.

✅ Strengths

Architecture & Design Excellence

• Perfect pattern consistency: Follows the existing wrapper pattern around native Salesforce APIs
• Comprehensive inheritance structure: MockDuplicates properly extends Duplicates with full override capabilities
• Fluent API design: Excellent chainable methods for test configuration (addRule().addMatch().addRecord())
• Clean abstraction: Proper separation between real and mock implementations

Code Quality

• Robust null safety: Extensive use of null coalescing (??) operators throughout (Duplicates.cls:74,84,133+)
• Proper lazy initialization: Properties are initialized only when accessed with appropriate fallbacks
• Exception handling: MockDuplicates properly validates input constraints (1-50 records, single SObject type)
• Memory efficient: Uses transient keyword appropriately to prevent serialization issues

Test Coverage & Mocking Framework

• Comprehensive mock capabilities: Full simulation of Datacloud APIs with configurable responses
• Fluent test configuration: Easy-to-use builder pattern for complex test scenarios
• Integration tests: Real API tests in DuplicatesTest.cls verify wrapper behavior
• Edge case coverage: Tests for errors, exceptions, and boundary conditions

⚠️ Issues Requiring Attention

Missing Test Coverage (As Noted in Review Comments)

1. source/classes/DatabaseLayerUtilsTest.cls:?: Missing tests for new SObjects.newSObjects() and SObjects.newSObject() methods
2. source/classes/DatabaseLayerTest.cls:?: Missing tests for new Duplicates property logic in DatabaseLayer

Documentation Improvements Needed

Multiple wiki files need style corrections to match existing documentation patterns (as noted in review comments):

• Remove excessive Returns sections
• Simplify examples to show basic usage only
• Follow consistent class reference file format

Minor Code Issues

1. source/classes/MockRecord.cls:?: Review comment indicates this should be removed (appears to be leftover code)
2. Case sensitivity in property access: source/classes/Duplicates.cls:510 - additionalinformation vs additionalInformation (potential Salesforce API casing issue)

🔒 Security & Performance Assessment

Security - No Concerns ✅

• No sensitive data exposure
• Proper use of sharing keywords (inherited sharing, without sharing)
• Safe JSON serialization/deserialization pattern (consistent with existing codebase)
• MockError class safely handles exception conversion without exposing internal details

Performance - Well Optimized ✅

• Lazy loading: Properties initialize only when accessed
• Efficient validation: Input validation happens early to fail fast
• Transient fields: Proper use prevents unnecessary serialization
• Minimal object creation: Reuses existing patterns for wrapper instantiation

Defensive Programming ✅

• Comprehensive null checks: Every property access is safely guarded
• Input validation: MockDuplicates enforces Salesforce API limits (1-50 records, single type)
• Graceful degradation: Returns empty collections instead of null when underlying data is missing

📋 Recommendations

High Priority (Address Before Merge)

1. Add missing tests for new DatabaseLayerUtils.SObjects methods
2. Add missing tests for DatabaseLayer Duplicates property switching logic
3. Remove unused code in MockRecord.cls as indicated by review comment

Medium Priority

1. Update documentation files to match existing style guidelines
2. Verify casing of additionalinformation property access in Duplicates.cls:510

Low Priority (Future Enhancement)

1. Consider adding bulk operation optimization for large result sets
2. Consider adding more specific exception types beyond HandledException

🎯 Overall Assessment

Rating: Excellent ⭐⭐⭐⭐⭐

This PR demonstrates exceptional engineering practices:

• Follows established patterns perfectly
• Comprehensive test coverage with minor gaps
• Excellent error handling and defensive programming
• Performance-conscious implementation
• Clean, maintainable code structure

The module integrates seamlessly with the existing codebase and provides a robust foundation for duplicate detection operations. With the minor test coverage additions and documentation updates, this will be a valuable addition to the library.
