If you need only 300 virtual users which can be simulated from a single machine without any issues - you don't need to run JMeter in distributed mode, most probably you can generate this load from a single machine, just. Controllers. Back to top 2. Solution: Tried 3 ways: if Event_RequestN created - put into variable specific value, then use it in IF-condition before 2nd user action with Event_RequestN; add action with specific assertion before 2nd user action with Event_RequestN and use $ {JMeterThread. Inside each Controller, there are multiple (2 or more) calls to the exposed ‘sibling’ endpoints. Add If Controller with the following condition: $ {__P (runsomesampler,)} == true.

The sixth and final step is to run and analyze the test plan. Put the request under the If Controller and use the following condition: ${__threadNum} == 1 This way JMeter will execute the sampler only for 1st thread. Composing the environment to be virtualized, described by a minimal set of information (e. getThreadNum() == 0 && vars. In the screenshot, for example there are 5 values which are expected to be sent over and over again until "SUCCESSFUL" is present in the response body, I am using a single thread, a counter and a WHILE.

This controller allows you to use multiple test plans in JMeter. In the figure below we have a test plan containing two Thread Groups. For example, if you add one HTTP Request to a Loop Controller with a loop count of two, and configure the Thread Group loop count to three, JMeter will send a total of 2 * 3 = 6 HTTP Requests. The Throughput Controller is used to control the processing of its child elements in terms of the total number of executions or the percentage of execution specified in its control panel. webdriver. I did it by using Beanshell Sampler as following:If I set >1 threads, it skipping if clause and sleep time is not activated.
