# Comprehensive Test Suite for ExecutorAdapter

This test suite provides comprehensive coverage for the ExecutorAdapter component,
focusing on security validation, parallel execution safety, and resource management.

## Test Coverage Areas:
- Execution planning and intent translation
- Parallel execution coordination and safety
- Resource allocation and management
- Error handling and retry mechanisms
- Security validation of execution parameters
- Performance and timeout handling
- Failure recovery and rollback procedures
