K6 – Performance Testing Masterclass with JavaScript

This course focuses on modern performance testing with **K6**, going beyond simple load generation to analyze, validate, and monitor system behavior effectively. You’ll learn how to: * Design realistic load tests for APIs and browsers * Use core K6 features like stages, thresholds, checks, tags, and custom metrics * Build real-world API flows (login, registration, transactions) with dynamic data handling * Write modular, scalable scripts using JavaScript best practices * Perform browser-level testing using K6 Browser + Playwright * Capture Web Vitals like LCP and CLS to validate user experience * Integrate with Grafana Cloud for real-time dashboards and monitoring * Add performance tests into CI/CD pipelines By the end, you’ll be able to build complete, production-ready performance testing frameworks with API testing, browser validation, and observability integrated together.
