// Load Testing Framework for BZZZ Integration Tests
|
||||
// This comprehensive load testing framework provides advanced load generation,
|
||||
// performance monitoring, and stress testing capabilities for the BZZZ system.
|
||||
//
|
||||
// Key Features:
|
||||
// - Multi-pattern load generation (constant, burst, ramp, sine wave)
|
||||
// - Role-based collaboration load simulation
|
||||
// - Performance monitoring with detailed metrics collection
|
||||
// - Real-time performance visualization and alerting
|
||||
// - Comprehensive load test reporting and analysis
|
||||
// - Resource usage tracking and optimization recommendations
