/**
|
||||
* @file nl2sql_integration-t.cpp
|
||||
* @brief Integration tests for NL2SQL with real database
|
||||
*
|
||||
* Test Categories:
|
||||
* 1. Schema-aware conversion
|
||||
* 2. Multi-table queries
|
||||
* 3. Complex SQL patterns (JOINs, subqueries)
|
||||
* 4. Error recovery
|
||||
*
|
||||
* Prerequisites:
|
||||
* - Test database with sample schema
|
||||
* - Admin interface
|
||||
* - Configured LLM (mock or live)
|
||||
*
|
||||
* Usage:
|
||||
* make nl2sql_integration-t
|
||||
* ./nl2sql_integration-t
|
||||
*
|
||||
* @date 2025-01-16
