Description

Overview

Add comprehensive unit tests for the database optimization features implemented in #97.

Background

The database optimization PR (#97) introduced several new features that would benefit from additional test coverage:

  • UPSERT operations
  • Batch loading for aspects
  • In-memory processing for descendant queries
  • Database maintenance scripts

Requirements

Test Coverage

  • Test UPSERT operation behavior with conflicts
  • Test batch loading performance improvement
  • Test edge cases for empty collections
  • Test error handling for database failures
  • Test maintenance script operations

Performance Tests

  • Benchmark N+1 query fix
  • Measure impact of new indexes
  • Compare recursive query performance

Success Criteria

  • All new code has >80% test coverage
  • Performance improvements are validated with benchmarks
  • Edge cases are properly handled

Related

  • Follows up on #97 (Database optimization)
  • Part of overall test coverage improvement

Contributor guide

Research direction
Familiarize yourself with the database optimization code from PR #97, then write unit tests covering UPSERT operations, batch loading, in memory processing for descendant queries, and database maintenance scripts. Focus on edge cases, error handling, and performance benchmarks.
