Thread Group Properties: number of threads : 600 ramp up period : 60 Loop count : 5, Add Sampler -> Flow Control Action Select Logical Action on thread as Pause Duration (milliseconds). Asking for help, clarification, or responding to other answers. 1 it's recommended to use JSR223 Test Elements and Groovy language for any form of scripting; If for some reason (I fail to see any valid reason though) you still want to do this using JSR223 Sampler instead of Flow Control Action sampler - the relevant code would be:All groups and messages. If you want to add a delay between each iteration of each thread add a Flow Control Action Sampler as the first sampler and set the delay in the controller. 54. Right-click on the ‘Test Plan’ node. Once the condition is met you can use Flow Control Action sampler to stop the current thread: Share. The flow control container lets you control how often the contained actions are executed. The main purpose of the If Controller is to control the JMeter execution script flow.

For example, if the test case describes the deletion of a user from the user database, adding the user is aThere are two parts to a Delay For action: the value (how many) and the unit (the type of time). I want to Control the Throughput at Transaction level, But not at Request/Hits Level. This could be an old bug in JMeter < 2. Pay attention to loops and other pieces of code that require a long execution time, they can also slow down the hit rate of your virtual users significantly. A simple JMeter test with sequential requests controlled by a Response Assertion. Recording Controller. Mark the installation checkbox, and select Install without restart.

Add a Thread Group to Test Plan. This field is required. Make the "token" Thread Group to loop forever. Consider replacing the Constant Timer with the Flow Control Action sampler, it doesn't generate any SampleResult and being called exactly where it's placed just like. Each Thread Group in a JMeter Test Plan simulates a particular real-world application scenario. The execution order of the elements in an Apache JMeter performance test plan is very important, it helps understand the timeline of events and how your test will behave. This HTTP. You can also use CLI mode to run remote tests. However, there are a few limitations:If you want to store the accessToken value into a JMeter property for using in other Thread Group(s) be aware that properties are global for the whole JVM and remain until JMeter is restarted so if you define a single accessToken property - each JMeter Thread (or iteration) will overwrite the value. Hover the mouse on ‘Add’. or add a Flow Control Action sampler between "Validate" and "Cancel" requests and configure it to "Pause" for 3000 milliseconds: Both options will create a 3 seconds delay between "Validate" and "Cancel" requests.
