A Dummy sampler


Though not part of the built-in JMeter samplers, this sampler can be added to your JMeter toolkit via the JMeter extensions project. We discussed this in detail in Chapter 5, Resource Monitoring, so if you don't already have it configured, please refer to that chapter to get the gist of it. This sampler generates samples with just the values that are defined for it. It comes in extremely handy when debugging post processors without having to repeat the entire execution of the test plan or waiting for the exact condition in the application under testing.

This component allows you to determine if the response should be marked a successful sample, what response code to return, the response message, the latency, and response times. In addition, it allows you to specify a request and a response, which can be anything you choose; for example, HTML, XML, and JSON.

Once the plugins have been properly installed into your JMeter instance, you should see additional samplers available...
