Performance and API Testing with JMeter

Every modern web application must be fast, reliable, and capable of handling heavy traffic. Testing these systems manually is impossible, which is why automated performance and API testing is a critical skill for developers and QA professionals. This text-based course guides you from absolute beginner to confidently designing and executing performance tests. You will learn how to simulate realistic user traffic, analyze system bottlenecks, and ensure your APIs perform under pressure. What you'll learn: - Understand foundational performance testing concepts, terminology, and key metrics. - Configure JMeter test plans, thread groups, samplers, and listeners. - Design robust API tests to validate response times, status codes, and payloads. - Apply assertions and regular expressions to extract and verify dynamic data. - Analyze test results to identify performance bottlenecks and resource constraints. - Integrate load testing concepts into modern CI/CD pipelines and automated workflows. The course begins with essential definitions and core testing principles before guiding you through building test plans step-by-step. You will progress from simple HTTP requests to complex multi-user simulation scenarios, reading clear explanations and analyzing practical configuration examples along the way. This course is designed for beginner QA engineers, developers, and system administrators looking to learn performance testing, with no prior JMeter experience required.
