使用KS检验进行回归检测

🌐 Regression detection with KS test

const { createHistogram } = require('node:perf_hooks');

const baseline = createHistogram();
const current = createHistogram();

// Record baseline and current latencies...

// D-statistic: 0 = identical, 1 = completely different
const d = baseline.ksTest(current);
if (d > 0.1) {
  console.log(`Possible regression detected (D=${d.toFixed(4)})`);
}
