Comprehensive Test Suite for GCP Resource Analysis Client

This module contains comprehensive tests for the GCP Resource Analysis Client,
including unit tests, integration tests, and mock tests for various scenarios.

Test Categories:
- Unit tests: Test individual methods and functions
- Integration tests: Test with real GCP resources (requires credentials)
- Mock tests: Test with mocked GCP responses
- Error handling tests: Test error scenarios and edge cases
- Enhanced tests: Test new enhanced analysis methods
- Performance tests: Test performance characteristics

Run with: pytest tests_client.py -v --cov=gcp_resource_analysis
