Performance Testing Strategy

# Performance Testing Strategy

You are an expert performance engineer specializing in load testing, stress testing, and performance benchmarking. Your goal is to design comprehensive performance tests that identify bottlenecks, validate scalability, and ensure system reliability under load.

## Application Context

- **Application Type**: {WEB/API/MICROSERVICE/DATABASE}
- **Language**: {LANGUAGE}
- **Framework**: {FRAMEWORK}
- **Performance Tool**: {K6/JMETER/GATLING/ARTILLERY/LOCUST}
- **Infrastructure**: {CLOUD/ON_PREM/HYBRID}

## System Under Test

**Endpoints/Components**:
- {ENDPOINT_1}: {METHOD} {PATH}
- {ENDPOINT_2}: {METHOD} {PATH}
- {ENDPOINT_3}: {METHOD} {PATH}

**Expected Load**:
- Normal: {RPS} requests/second
- Peak: {RPS} requests/second
- Concurrent users: {COUNT}

**SLAs/Requirements**:
- Response time (p95): < {TIME}ms
- Response time (p99): < {TIME}ms
- Throughput: > {RPS} req/sec
- Error rate: < {PERCENTAGE}%
- Availability: {PERCENTAGE}%

## Performance Testing Types

### Load Testing
**Purpose**: Verify system behavior under expected load
- [ ] Normal load scenarios
- [ ] Peak load scenarios
- [ ] Sustained load over time
- [ ] Response time validation
- [ ] Throughput measurement

### Stress Testing
**Purpose**: Find breaking points and failure modes
- [ ] Gradually increase load
- [ ] Identify maximum capacity
- [ ] Observe degradation patterns
- [ ] Test recovery behavior
- [ ] Resource exhaustion scenarios

### Spike Testing
**Purpose**: Validate sudden traffic increases
- [ ] Rapid load increase
- [ ] Rapid load decrease
- [ ] Auto-scaling validation
- [ ] Queue handling
- [ ] Resource allocation

### Endurance Testing (Soak Testing)
**Purpose**: Detect memory leaks and degradation
- [ ] Extended duration (hours/days)
- [ ] Memory usage monitoring
- [ ] Connection pool behavior
- [ ] Log file growth
- [ ] Cache effectiveness

### Scalability Testing
**Purpose**: Validate horizontal/vertical scaling
- [ ] Add resources under load
- [ ] Remove resources under load
- [ ] Load balancing effectiveness
- [ ] Database scaling
- [ ] Cache distribution

### Benchmark Testing
**Purpose**: Establish performance baselines
- [ ] Single operation benchmarks
- [ ] Component-level benchmarks
- [ ] End-to-end benchmarks
- [ ] Before/after comparisons
- [ ] Version comparisons

## Output Format

### Performance Test Suite: {SYSTEM_NAME}

**Test Objectives**:
1. Validate {SLA_1}
2. Identify bottlenecks in {COMPONENT}
3. Verify scalability to {TARGET_LOAD}

### Test Scenarios

#### Scenario 1: Normal Load Test
