Load Test Builder

负载测试构建器

Validate system performance under realistic and stress conditions.
验证系统在真实场景与压力条件下的性能表现。

Core Workflow

核心工作流程

  1. Define scenarios: User journeys and load patterns
  2. Set thresholds: Performance requirements
  3. Configure load: Ramp-up, peak, duration
  4. Run tests: Execute load scenarios
  5. Analyze results: Metrics and bottlenecks
  6. Integrate CI: Automated performance gates
  1. 定义测试场景：用户流程与负载模式
  2. 设置阈值：性能要求
  3. 配置负载：增量加载、峰值、持续时间
  4. 运行测试：执行负载场景
  5. 分析结果：指标与瓶颈
  6. 集成CI：自动化性能门禁

Results Analysis

结果分析

javascript
// scripts/analyze-results.js
import fs from 'fs';

const results = JSON.parse(fs.readFileSync('results.json', 'utf8'));

const summary = {
  totalRequests: results.metrics.http_reqs.count,
  avgDuration: results.metrics.http_req_duration.avg,
  p95Duration: results.metrics.http_req_duration['p(95)'],
  p99Duration: results.metrics.http_req_duration['p(99)'],
  errorRate: results.metrics.http_req_failed.rate,
  throughput: results.metrics.http_reqs.rate,
};

console.table(summary);

// Check thresholds
const passed =
  summary.p95Duration < 500 &&
  summary.p99Duration < 1000 &&
  summary.errorRate < 0.01;

process.exit(passed ? 0 : 1);

Best Practices

最佳实践

  1. Start small: Gradually increase load
  2. Use realistic data: Production-like scenarios
  3. Monitor everything: Backend metrics too
  4. Set thresholds: Define pass/fail criteria
  5. Test regularly: Catch regressions early
  6. Isolate environment: Dedicated test environment
  7. Document findings: Track improvements
  8. Include think time: Simulate real users
  1. 从小规模开始：逐步增加负载
  2. 使用真实数据：模拟生产环境场景
  3. 全面监控：同时跟踪后端指标
  4. 设置阈值：定义通过/失败标准
  5. 定期测试：尽早发现性能退化
  6. 隔离测试环境：使用专用测试环境
  7. 记录发现：跟踪性能改进
  8. 加入思考时间：模拟真实用户行为
