Gatling Fundamentals for API Stress Testing with Scala

In today's fast-paced digital landscape, slow APIs can break user trust and damage business reputation. Understanding how your services perform under heavy load is essential before deploying them to production. This text-based course guides you through the core principles of performance testing using Gatling and Scala, helping you transition from a beginner to a confident practitioner who can design and execute robust stress tests. What you'll learn: - Understand foundational performance testing concepts, including virtual users, throughput, and response times. - Write clear and maintainable simulation scripts using Gatling's Scala DSL. - Configure diverse load injection profiles to mimic real-world traffic spikes and steady-state usage. - Analyze Gatling HTML reports to identify latency issues, error rates, and system limitations. - Structure reusable test scenarios with custom feeders, assertions, and protocols. - Integrate your performance tests into modern CI/CD pipelines for continuous validation. The course begins with essential terminology and the architecture of Gatling before moving into practical script creation. You will progress step-by-step through writing scenarios, managing test data, and analyzing execution reports to make data-driven optimization decisions. This course is designed for QA engineers, developers, and system architects who are new to performance testing or Gatling. No prior experience with Scala is required, as we cover the necessary language basics to get you started. Start reading today to build faster, more resilient APIs.
