This is where we introduce the Switch Controller which to be honest is not going to magically help us in the creation of complex scenarios in JMeter but we will come to that bit soon. Let's consider an example of Random Order Controller, where Thread Group contains "Number of Threads" to "1", "Loop Count" to 5, and a total of "4" Samplers (Http requests). Loop Controller will run the samplers/requests stored in it for the definite number of times or forever ( if forever checkbox is selected ). Listeners, may be placed directly under the test plan, in which case they will apply to all the thread groups. rev2023.7.14.43533.

Instead, it does not have control over per unit of time, but this functionality is still somewhat parallel to what is usually wanted to perform, which is limiting the specific requests execution amount. Lets set the iteration as 10, add JSR223 Sampler in each Simple Controller and take a console log to see how it is going to work. Simple Controller Loop Controller Once Only Controller Recording Controller Throughput Controller Interleave Controller Random Controller If Controller While Controllers Real Time Example JMeter's Recording Template Conclusion Recommended Reading Pre-Processors These are the elements which are executed before a sampler is executed. Logic Controllers let you define the order of processing request in a Thread. Does each new incarnation of the Doctor retain all the skills displayed by previous incarnations?

If you don't want to run a certain part of the test fragment you have 2 options: Thanks for contributing an answer to Stack Overflow! For Example, you have defined 4 Http requests under Random Controller, then these requests will be sent in random order and their order of execution will be decided on run-time. Do all logic circuits have to have negligible input current? The Switch Controller is to quote from the JMeter documentation: The Switch Controller acts like the Interleave Controller in that it runs one of the subordinate elements on each iteration, but rather than run them in sequence, the controller runs the element defined by the switch value. If Simple Controller 1 is disabled, it will run Simple Controller 2 successfully. Loop Controller . While the main idea is pretty simple, there are many questions and issues around this controller. Throughput, essentially, is the number of requests executed per unit of time.
