New Google Test Suite Added to Firebird ODBC Driver

A major update has been merged into the FirebirdSQL/firebird-odbc-driver repository (PR #276), introducing a comprehensive Google Test suite to establish a strong regression testing baseline for the project. Authored by fdcastel, this addition is a crucial stepping stone before making future bug fixes or CI/CD improvements.

Key Highlights:

• Extensive Coverage: The PR adds a massive suite of 375 tests across 38 test suites, designed to exercise the Firebird ODBC driver directly through the standard ODBC API via the Driver Manager.
• Baseline Establishment: No driver source code was modified in this update. The goal is strictly to document what the current driver can do and precisely identify where improvements are needed.
• Pass vs. Skip Strategy: Out of the box, 230 tests pass, confirming that core features like data types, parameter binding, and catalog functions work correctly. The remaining 145 tests are skipped gracefully, each serving as a documented placeholder for known gaps or missing features (like ODBC 3.8 compliance and specific crash fixes).
• Future-Proofing: This sets up a perfect “regression gate.” As future patches and bug fixes are submitted, developers can simply remove the SKIP markers to activate the corresponding tests, proving that the fix works and preventing regressions.
• Standalone CMake Integration: The tests are housed in a self-contained CMake project that fetches Google Test, paving the way for easier integration into a future root CMake build.

This foundational work makes contributing to the Firebird ODBC Driver significantly safer and more measurable going forward!
