Performance Testing Fundamentals Using Apache JMeter Overview

This four-day, hands-on training course equips QA testing professionals with the foundational knowledge and practical skills required to plan, design, execute, monitor, and analyze basic performance tests using Apache JMeter.

Participants will learn the different types of performance testing, including baseline, load, stress, spike, endurance, volume, scalability, and capacity testing. They will understand when each test type should be used and how it supports performance-risk assessment and system-readiness decisions.

Using standard training applications and sample APIs, participants will build JMeter test plans, create realistic workloads, apply parameterization and correlation, execute controlled tests, and analyze key performance indicators such as response time, throughput, latency, error rate, and percentile results.

The course emphasizes team-based exercises and practical scenarios suitable for a single QA testing team. By the end of the training, participants should be able to conduct basic performance testing independently, interpret JMeter reports, identify potential performance problems, and communicate findings to developers, technical teams, and business stakeholders.

 

Duration 4 Days – 28 hrs.
