I'm using ${JMeterThread. So to explain again: Run on active_status_1 -> if active -> report and stop the loop. 1. Include Controller. It allows to define a behavior which occurs on a certain condition. The value of the parameter “param_1” should not be less than 9. These drive the processing of a test. This was accomplished by creating a combination of config element- random variable and an IF controller. This controller allows you to use multiple test plans in JMeter. Put the HTTP Request sampler (or any other sampler if you’re using a different protocol) under the While Controller. You will create five users that send requests to two pages on the JMeter Web site. jmx files into you tests and therefore the same benefits we saw with using our Module Controller are true here as well. apache. I tried following for IF controller but seems not working :The JMeter approach: for the situation I presented, the API calls were already defined in the JMeter application, so it was more convenient to integrate a solution into the existing tests. 162k 5 5 gold badges 85 85 silver badges 134 134 bronze badges. This way each thread will read one line from users. xml file. 2. The loop index is built into JMeter 4. it will save response code of the sampler into ${code} JMeter Variable.

Each JMeter thread will send the requests in the following order: Home Page, Interleaved, Bug Page, Interleaved, CVS Page, Interleaved, and FAQ. In one thread group Flow Control is used to repeatedly call API after every 10 minutes, in another thread group it is used to exit the jmeter test. last_sample_ok pre-defined variable. Getting the Server ResponseJMeter Function or Variable - the While Controller’s children will be run until a variable or function evaluation result is “true”. Your approximately current Scenario: Both Module Controllers refer to the 1st Simple Controller. So, it appears the best way to exercise the SMTP Sampler is to use the JMeterThread. Enter module1 in the name. response code as well as. How about reading JMeter documentation: JMeter will expose the looping index as a variable named jm __idx. .

ThreadGroup + Http Request + CSV Data Set Config -> set input and expected result + HTTP Header Manager -> get token from previous request + Regular Expression Extractor -> get Response Code + if Controller OK ($ {responseCode}=="200") + JSON Assertion + if Controller NOK. And Yes, the If Controller is enabled. Improve this answer. Attempt to retry the block of code a maximum of y number of times. $ {__javaScript ("$ {myVar}" != "<EOF>",)} Note: Make sure to substitute the variable. Now I am not sure what exactly I should write for If controller to tell if previous URL contains word "retailer" then follow all HTTP requests which are under IF controller.

TestingWithArif TestingWithArif. An easier option would be using Switch Controller, from implementation and especially performance perspectives it is the optimal solution. You can use JSON Extractor which provides possibility to execute arbitrary JsonPath queries against the response (or a JMeter Variable) and save the evaluation results into another JMeter Variable. Select the workbench. User variables can be referenced in any field of any JMeter Component. While working with JMeter, I discovered that JMeter does not easily determine the value of a.
