Performance and API Load Testing with JMeter

In today's fast-paced digital landscape, application speed and reliability are critical to user retention. Software testers and developers must know how to identify performance bottlenecks before code reaches production. This comprehensive written course guides you through the fundamentals of performance, load, and stress testing using JMeter. You will gain the skills to build robust test plans, simulate realistic user traffic, analyze test results, and script custom behaviors to validate both web applications and APIs. What you'll learn: - Understand core performance testing concepts, including load, stress, spike, and endurance testing. - Configure JMeter test plans using thread groups, samplers, listeners, and assertions. - Design functional and load tests for REST and SOAP APIs, validating response data and performance metrics. - Apply JSR223 scripting with Groovy for advanced dynamic data handling and custom test logic. - Configure database performance tests using JDBC connections to identify slow queries. - Analyze test reports and metrics to locate system bottlenecks and performance degradation. The course begins with foundational performance terminology and installation, then guides you step-by-step through recording scripts, parameterization, API testing, and advanced scripting techniques. This course is designed for QA engineers, software testers, and developers who are new to performance testing, with no prior JMeter experience required.
