Overview

Set up synthetic monitoring to automatically simulate real user journeys, API workflows, and critical business transactions to detect issues and validate performance.

When to Use

End-to-end workflow validation
API flow testing
User journey simulation
Transaction monitoring
Critical path validation

Quick Start

Minimal working example:

// synthetic-tests.js
const { chromium } = require("playwright");

class SyntheticMonitor {
  constructor(config = {}) {
    this.baseUrl = config.baseUrl || "https://app.example.com";
    this.timeout = config.timeout || 30000;
  }

  async testUserFlow() {
    const browser = await chromium.launch();
    const page = await browser.newPage();
    const metrics = { steps: {} };
    const startTime = Date.now();

    try {
      // Step 1: Navigate to login
      let stepStart = Date.now();
      await page.goto(`${this.baseUrl}/login`, { waitUntil: "networkidle" });
      metrics.steps.navigation = Date.now() - stepStart;

      // Step 2: Perform login
      stepStart = Date.now();
      await page.fill('input[name="email"]', "[email protected]");
      await page.fill('input[name="password"]', "password123");
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Test critical user journeys
Simulate real browser conditions
Monitor from multiple locations
Track response times
Alert on test failures
Rotate test data
Test mobile and desktop
Include error scenarios

❌ DON'T

Test with production data
Reuse test accounts
Skip timeout configurations
Ignore test maintenance
Test too frequently
Hard-code credentials
Ignore geographic variations
Test only happy paths
