Goal-4-Task-3 Test Plan: SQLite Adapter Implementation

Test Scope

This test plan covers the verification of the SQLite adapter implementation against the memory interface specification, with a focus on:

1. CRUD operations compatibility with memory interface
2. Transaction support (begin/commit/rollback)
3. Performance benchmarks
4. Security compliance (AES-256-GCM, RBAC, audit logging)
5. Test coverage of new functionality

Test Environment

• Python 3.10+
• SQLite 3.38.5+
• pytest for test execution
• pytest-benchmark for performance testing
