Make sure you have sufficient test data to simulate ‘Sequential Each Occurrence’ scenario.Figure 09 Figure 11 Figure 12 Important Notes: Now, run the test and see the result in the ‘View Result Tree’ listener. Now, I will modify the request as per the set-up to pass the different value from parameter list at each occurrence. Let’s consider below is my original request. To illustrate the scenario, I have used a dummy sampler. Now, come to sampler request part where we will use these variables. So, here we have completed the set-up to generate the sequential value at each occurrence of the parameter.

This code will read the value from the CSV file and assign it to the variable name generated by the counter. Now, write the given code the BeanShell Sampler. The ‘Counter’ element is used to generate a new variable each time in which parameter value will be substituted in the sampler request (Pay attention to number format as in the similar way it has to be substituted in sampler request) Figure 05
FLEMING, Parameter estimation following group sequential hypothesis testing, Biometrika, Volume 77, Issue 4, December 1990. ‘Sharing mode’ must be set as ‘Current thread’. Parameter estimation techniques which fail to adjust for the interim analyses of group sequential test designs will introduce bias in much the same wa. Make sure you provide correct CSV file path and variable name. Let’s have a look at the CSV Data Set Config and apply the same in your scenario. I want to use 3 values from the list within the same iteration. In this example, I have taken 3 as loop count i.e. CSV file has the following values: Figure 01: CSV File with Parameter ValueĪdd all the above-mentioned elements under a thread group (Refer to Figure 02) Figure 02Ĭlick ‘Loop Controller’ and provide the value in ‘Loop Count’ field which should be equal to the number of occurrences.
For this purpose, you would require 4 elements to add under Thread Group:

In this article, you will learn how to implement the sequential value of a parameter at each occurrence in JMeter. As this feature is not directly available in JMeter, so you need to make the use of some of the existing elements in the JMeter and implement the mode of accessing the parameter value as required. One of them is not getting some important features directly like Parameter Setting which is easily available in LoadRunner (Refer LoadRunner Parameter Settings). But lack of some features restricts JMeter to become a powerful tool. JMeter is a freeware tool which is in high demand.
