"""Comprehensive tests for mcrentcast MCP server.

Tests all 13 MCP tools with various scenarios including:
- API key management
- Property search operations
- Caching functionality (hits/misses)
- Rate limiting behavior
- Error handling and edge cases
- Mock vs real API modes

NOTE: These tests use outdated testing patterns from before the FastMCP refactoring.
They are marked for skipping until they can be updated to use the FastMCP Client pattern.

See tests/test_smoke.py for working tests using the current FastMCP testing approach.
