Load Testing Essentials: JMeter, Gatling, and k6

Software performance can make or break a user's experience, yet testing for high traffic is often overlooked until it is too late. This text-based course helps you build a solid foundation in load and performance testing from the ground up. You will transition from understanding basic performance concepts to designing, running, and analyzing load tests using popular tools. By studying the written explanations and practical code examples, you will learn how to identify system bottlenecks and ensure application reliability. What you'll learn: - Understand core performance testing terminology, metrics, and methodology - Write and configure load testing scripts using JMeter, Gatling, and k6 - Monitor system health and analyze performance metrics using modern observability tools like Grafana - Integrate performance tests into automated CI/CD pipelines for continuous feedback - Identify common architectural bottlenecks, including database and network latency - Design realistic test scenarios that mimic actual user behavior under heavy load The journey begins with fundamental testing concepts and terminology before moving into step-by-step written guides for scripting with JMeter, Gatling, and k6. You will then explore how to set up basic monitoring and analyze test results to make data-driven optimization decisions. This course is designed for beginner QA engineers, developers, and system administrators who want to learn performance testing. No prior load testing experience is required.
