Learn API & Browser Load Testing using K6 -jаvascript, Web Vitals, Core Metrics & Grafana cloud Integration

What you'll learn

✓ Design and implement Load, Stress, Spike and Soak tests using K6 with real-world performance scenarios.
✓ Design realistic load models using stages, thresholds, checks, tags and custom metrics.
✓ Build end-to-end API load testing flows in K6 including registration, login and transactional scenarios.
✓ Implement browser-level load testing using K6 Browser library with Playwright integration.
✓ Measure and analyze API and Browser performance metrics including Web Vitals and page-wise tracking.
✓ Integrate K6 with Grafana Cloud to visualize, monitor and analyze performance metrics in real time.
✓ Execute end-to-end performance testing projects from planning to result interpretation.

Requirements

● None. jаvascript basics are already covered as part of the course.

Description

Performance testing today is not just about generating load — it is about measuring, analyzing, and validating system behavior across APIs and browsers with proper observability.
This K6 Performance Testing MasterClass teaches you how to design complete performance testing solutions using K6 and jаvascript — covering both backend API flows and frontend browser-level validation.
You will start by mastering core K6 concepts including stages, thresholds, checks, tags, and custom metrics. You will learn how to design realistic load models and validate non-functional

Requirements

effectively.
The course then walks you through building real-world API test flows such as registration, login, and transactional chains. You will extract dynamic data from JSON responses, implement assertions, and structure modular K6 scripts using jаvascript best practices.
Beyond APIs, you will integrate the K6 Browser library with Playwright to perform browser-level load testing. You will capture Web Vitals metrics such as LCP and CLS, track page-wise performance, and validate real user experience under load.
A dedicated section covers Grafana Cloud integration, where you will stream K6 metrics to Grafana dashboards for real-time monitoring, visualization, and performance analysis. This bridges the gap between load generation and observability — a key skill in modern DevOps environments.
Finally, you will integrate K6 tests into CI/CD pipelines to automate performance validation.
By the end of this course, you will be capable of designing scalable, observable, production-ready performance testing frameworks using K6.
This is a complete API + Browser + Observability Performance Engineering MasterClass.
