Nonfunctional tests like performance tests are often left until the end of the delivery cycle because they can be expensive in terms of time, resources, and effort. However, performance issues can be difficult to resolve when found late in the software development lifecycle. Apache JMeter is an open source tool designed to load test functional behavior and measure performance. JMeter can be used to develop, manage, and execute load and performance tests while the code is being developed, rather than waiting to do performance testing until just before release. By using it early in your delivery pipeline, you can find and resolve performance issues as soon as they are introduced. Join Bob Foster as he shows how to use JMeter, design test scenarios, parameterize and seed tests, and execute those tests within Jenkins as part of a CI/CD pipeline.
