…tools - Add ListProceduresAndFunctions tool to list all stored procedures and functions - Add DescribeProcedureOrFunction tool to get detailed information about procedures/functions - Include parameter information, definitions, and metadata - Both tools follow existing patterns with proper error handling and logging
…cuteFunction tools - Add ToolsUnitTests.cs with 16 fast unit tests covering: * Parameter validation for stored procedures and functions * Constructor and interface validation for Tools class * SqlConnectionFactory interface verification * Various parameter types and null value handling - Add comprehensive test documentation (README.md) explaining: * Separation between unit tests (fast, no dependencies) and integration tests * Test execution commands and prerequisites * Test coverage matrix for all tools * Best practices following Test Pyramid principle - Maintain clean architecture: * Unit tests (16) - Fast validation without database dependencies * Integration tests (14) - End-to-end database testing (unchanged) * Total coverage: 30 tests across all MCP tools This addresses missing test coverage for the ExecuteStoredProcedure and ExecuteFunction tools added in previous commits while maintaining proper separation of concerns between unit and integration testing.
