Definition of JMeter Loop Count
JMeter provides different types of functions to the user, in which that loop count is one of the functions that is provided by the JMeter. Basically, loop count means we can set the number of iterations for every user as per our requirement. A typical type of circle is the counting circle, in which the circle rehashes a proper number of times. An including circle regularly utilizes a variable to count from some underlying worth to some last worth. This variable is regularly called the list variable. JMeter we can set the number of users we need to test API for 100 users at a time so at that time we can use the loop count function.
What is JMeter loop count?
Rationale Controllers are vital Test Plan components that are liable for getting sorted out the request for execution of Samplers and different components added. Fundamentally, it allows you to control when and in which example to send Requests to the Server. Before we begin discussing Loop Controllers, how about we perceive how we can add Logic Controllers.
Rationale Controllers can be added under Thread Group and furthermore as an offspring of another regulator.
Many people are getting confused about the utilization of JMeter Loop Count and JMeter Thread Count and all the more critically, what will it mean for their heap test. Do you know the responses? The following are two situations:
Situation 1: If the quantity of string count is 20, the increased time is 20, and the loop count is 1.
Situation 2: If the quantity of string count is 2, increase time is 2, and circle count is 20.
What is the distinction between the two situations and will it have comparable execution sway? What will be the postponement between demands in situation 2? Will every one of the strings stay alive in Scenario 2? Many people know about the way that a string mimics a client and circle count implies the times the string will make the demand. Let’s get straight to the point on a portion of the subtleties. In both situations, 20 strings will be made. In situation 2 when another string begins the more established string stays alive. The thing that matters is that in situation 1, strings might work equally, and in situation 2 each string begins after the last one stop. What’s more there is no postponement between strings except if you indicate them.
How to use JMeter loop count?
Now let’s see how we can use loop count in JMeter with an example as follows. When we try to create the advanced test plan in JMeter, that means when we increase the number of users at that time we can use the loop count function to handle this condition.
First, we need to create a Test Plan as shown in the following screenshot as follows.
After creating the Test Plan we need to add the Thread Group and inside the thread group, we can add the multiple samplers as per our requirement as shown in the following screenshot as follows.
Now we need to add the listener into the Test Plan to view the result of test execution as shown in the following screenshot as follows.
Here we successfully created a Test Plan. Now consider one scenario: we need to execute or maintain the concurrency for 500 users for 2 hours. So how we can handle this scenario, the answer to this question is loop count. So we can easily handle this scenario by using loop count. So add loop counts that are present in the thread group as shown in the following screenshot as follows.
We can see that initially, loop count is one we can manage as per our requirement, so here we increase the number of thread users and loop count as shown in the following screenshot as follows.
Now save the Test Plan and run, after execution of the Test Plan we can see the output of the Test Plan as shown in the following screenshot as follows.
In the above screenshot, we can see, here we add 500 users and, the ramp-up time is 2 seconds and the loop count is 1 then we get the above screenshot. Now increase loop count and let’s see what happens as shown in the following screenshot as follows.
Now save the Test Plan and execute, after execution of the Test Plan we can see the output in the view tree as shown in the following screenshot.
Using Config Element in JMeter loop count
Now let’s see how we can configure elements for loop count in JMeter as follows.
Let’s consider one scenario: suppose we need to add different entities in a loop by using an HTTP request, so generally, what we do is copy and paste but this is a bad choice. Now assume we do the same scenario 200 and 300 times so it is difficult.
So better way we need to define the counter inside the thread group and configure it as per our requirement as shown in the following screenshot as follows.
The same scenario we can resolve by using counter function and script.
JMeter loop count Features
Now let’s see what features of loop count in JMeter are as follows.
- There are a few situations where we want to execute a particular area on different occasions and not the entire test suite. We can consider underneath referenced situation for instance:
- Every client Logs into the application.
- Perform Search for somewhere around 15 distinct items.
- Client Logs out from the application.
For the previously mentioned situation, we can’t utilize the “Loop Count” from the Thread Group as it applies to the whole utilitarian stream. Such prerequisites can be dealt with by adding Loop Count under the Thread Group.
