Load Testing Spring Boot Applications with K6

Is your Spring Boot application ready to handle real-world traffic? Ensuring your web services remain fast and stable under heavy loads is critical for modern software development. This text-only course teaches you how to design, execute, and analyze performance tests using K6, a modern and developer-friendly load testing tool. You will learn to set up realistic testing environments and identify bottlenecks before they affect your users. What you'll learn: Understand the core concepts of performance, stress, and load testing; Set up a local Spring Boot application environment using Docker Compose; Write structured K6 testing scripts using modern JavaScript syntax; Simulate realistic user traffic patterns with virtual users and ramp-up phases; Analyze key performance metrics such as latency, throughput, and error rates; Identify database and application bottlenecks within a Spring Boot environment. The course starts with foundational definitions of performance testing and an introduction to K6 syntax. You will then progress through setting up your testing environment using Docker Compose, writing your first load test, and interpreting the results to optimize your application. This course is designed for beginner backend developers, QA engineers, and DevOps enthusiasts who are new to load testing and want to verify the reliability of Spring Boot applications. No prior performance testing experience is required. Start reading today to build faster, more resilient Spring Boot applications.
