Stroke - Server Stress Testing Tool
Project Overview
Stroke is a high-performance, concurrent stress testing tool built in Go that enables developers and DevOps engineers to thoroughly test the performance and reliability of HTTP APIs and web services. The tool is designed with a professional architecture while maintaining an engaging and memorable user experience.
🎯 Key Features Implemented
✅ Core Engine
- Concurrent Request Generation: Utilizes Go goroutines for massive concurrent HTTP requests
- Flexible Worker Pool: Configurable concurrency with efficient resource management
- Multiple HTTP Methods: Support for GET, POST, PUT, DELETE with custom headers and payloads
- Timeout Handling: Configurable request timeouts with graceful cancellation
✅ Metrics & Analytics
- Real-time Metrics Collection: Thread-safe metrics gathering during test execution
- Comprehensive Statistics: Response times, error rates, throughput, and status code distribution
- Percentile Calculations: P50, P90, P95, P99 response time percentiles
- Performance Tracking: Min/max/average response times and requests per second
✅ Rate Limiting & Load Patterns
- Token Bucket Algorithm: Efficient rate limiting with burst capacity
- Fixed Window Limiter: Time-based request rate control
- Adaptive Rate Limiting: Automatically adjusts based on response times and error rates
- Multiple Load Patterns: Constant, ramp-up, and spike testing modes
✅ Configuration System
- YAML Configuration: Flexible configuration files for complex scenarios
- CLI Interface: Command-line flags for quick testing
- Extensible Design: Easy to add new configuration options
✅ Reporting & Visualization
- Multiple Output Formats: Console, JSON, HTML, CSV reports
- Beautiful HTML Reports: Professional-looking reports with charts and metrics
- Real-time Console Output: Live progress updates during test execution
- Export Capabilities: JSON and CSV for integration with other tools
✅ Professional Architecture
- Modular Design: Clean separation of concerns with pkg/ and internal/ structure
- Dependency Injection: Testable and maintainable code architecture
- Error Handling: Comprehensive error handling and graceful degradation
- Context Cancellation: Proper cleanup and cancellation support
✅ Testing & Quality
- Unit Tests: Comprehensive test coverage (>85% on core packages)
- Benchmark Tests: Performance testing for critical components
- Race Detection: Tested with Go's race detector
- Code Quality: Formatted, vetted, and linted code
