In your case, that is set to 0. You can easily define the Loop count under Thread Group and all the requests will be executed (Thread Count*Loop Count) times. Let's look at the following scenario: 1,000 threads as target load 0 seconds waiting after the test starts 0 threads run at the immediate beginning of the test Now click on add which shows many options following Thread then select thread now we can find the Thread group option. Add JMeter elements Add HTTP request default to www.google.com. Create another HTTP Request and then I am going to add UiPath Link as shown below. Ramp-Up Period Defines how long it will take JMeter to get all threads running. Finally enter a value of 2 in the Loop Count field. Define the JMeter Counter Define a Counter inside the Loop Controller and configure it as follows. How to download 'Concurrency Thread Group' plug-in? Add a Loop Controller and set the "Loop Count" to 5 2. Ramp-up Period defines the time period where all user must be started. Let's walk through the differences. Now we determine what JMeter elements in this test. Remove the loop controller called 'Step 1'. Loop Controller in Apache JMeter. 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. Each Thread Group has their own loop count. vars - shorthand to JMeterVariables class which holds current JMeter variables. We can use the getIteration() function to get the thread loop count in properties and also in shell. The ramp-up period which is the number of seconds that JMeter will take to create all 'n' threads gradually instead of starting the system with 'n' threads in one go. The Thread Group tells JMeter: the number of users (called threads) you want to simulate , how often the users should send requests, and how many requests they should send. Then, add the Stepping Thread Group from the Test Plan. Adding Loop Controller Right Click Thread Group -> Logic Controller -> Loop Controller Step 2) Configuring Loop Controller Add value 50 to Loop Count field as below figure. Percent Execution - This selection will make Jmeter execute only a certain percentage of total iterations for Samplers placed under this controller. You can do it like $ {__BeanShell (vars.getIteration ();,)} where: __Beanshell - JMeter function allowing execution of arbitrary Beanshell script. Loop count (How many times the test should be looped). If i put 100 in the number of threads and a loop count of 1 2. Thread Group 1 - Hotel Search will have thread count as 400 users, Thread Group 2 - New User Registration will have 100 Users, Thread Group 3 - User Login & Compare Hotels will have 200 Users, Thread Group 4 - User Login & Book Hotel will have 200 Users & Thread Group 5 - Cancel Booking will have . 1 Answer. 1. In Thread Group GUI, you can control the number of simulated users (threads), the ramp-up time (how long it takes to start all the threads), the loop count (or iteration count, and optionally, a start and stop time for the test. Re: Thread Group \"Loop Count\" Not Working in Jmeter. Each thread will start after 1 (10/10) second after the previous thread had begun. The setUp Thread Group consists of a CSV Data Set Config with a reference to the CSV file containing the list of users to register (first name, last name and email address) In our example, we send the registration request with 3 variables: "firstName", "lastName" and "emailAddress". Here's another example from the JMeter Thread Group user manual: If we now replace our static Loop Count value in the Thread Group to use our ITERATION_COUNT Property. Finally, select the thread group. Lets create a property file as given below. The different types of Samplers like HTTP requests are added as child of these Thread Group elements to simulate the requests made by users to the server. As shown in the image below: Components of Thread Group The Thread Group Panel holds the following components 1) Action to be taken after a Sampler Error Number of threads (the number of users you are testing). If I understand it correctly, the sampler should only run once . The first loop is done, then the second loop will run, and after the second loop ended, the third loop will run, and so on. For example, if the loop count is 2 and number of threads is 100 then the script will run 200 times. A typical type of circle is the counting circle, in which the circle rehashes a proper number of times. In other words, the loops run sequentially inside the thread group. How to Use JMeter for Performance & Load Testing Step 1) Add Thread Group. In JMeter Thread Group you can use Ram Up Period (In Seconds) field to calculate how many request you want to send to server. to jmeter-plugins. Loop Count: It is the number of executions for the script. # Anonymous User - Product Search group1.usercount=10 group1.rampup=10 group1.duration=600 # New User Registration group2 . The loop count can be infinite and one can run concurrent threads for a specific amount of time by checking on Specify Thread Lifetime and adding Duration say 60 seconds. Stack Overflow - Where Developers Learn, Share, & Build Careers We can launch the Thread Group in JMeter by following the path- Right Click on Test Plan-> Hover over Threads (Users)-> Click Thread Group Thread Group Properties Click on the link to download Concurrency Thread Group JMeter Plugin Unzip the folder Copy the file jmeter-plugins-cmn-jmeter-<version>.jar to lib folder of Apache JMeter apache-jmeter-<version> ->lib -> Paste jmeter-plugins-cmn-jmeter-<version>.jar In the same way, add one more HTTP Request and then add one more link in the path. See How to use BeanShell: JMeter's favorite built-in component guide for more information on Beanshell . In essence, every thread imitates a single authentic user request to the server. Please follow below . http503.com. Ramp Up Time (sec): 0. That's where Looping comes into the picture. The field "Loop Count" is used to set the number of times each thread should run for eg. Stop thread called threadName: stop JMeter thread interrupt JMeter thread interrupt underlying thread. (If you leave it blank, the Counter will start from zero.) 100. You can also check the "Per User" checkbox to control this at a user level. Ramp-up time (how much time you want to allow the Thread Group to go from 0 to 3 users). The Thread Count and The Loop Counts are different. I am setting up a Concurrency Thread Group with thse parameters: Target Concurrency: 1. Scheduler Configuration You can configure the start and end time of running the test. 3 Answers Sorted by: 1 Use the field "Number of Threads" to set as many threads as required for your load test (eg. If i put 10 in the number of threads and loop count of 10 Assuming you use a UserDefinedVariables element with the 10 accounts each as a variable value, the two approaches you outline should indeed reuse the accounts and behave functionally equivalently. Launch JMeter in your system. As implied by the name, a thread group consists of a number of threads that are working on the same situation. Start JMeter Select Test Plan on the tree Add Thread Group Open the thread group panel by Right Click on Test Plan and then going to Add >> Threads >> Thread Group. in property ${__BeanShell(vars.getIteration();,)} You can select the checkbox 'Forever' if you want to threads to run as the checkbox suggests. The Thread Group Control Panel includes: Itsname. Inside the thread group there is one sampler that perfoms a query. For Example, Thread Group is configured to have 10 users and loop count is 5. The number of threads for each group can be set using the settings for a thread group. . This property tells JMeter how many times to repeat your test. Number of threads: 10, Ramp-Up period: 10 seconds and Loop Count: 1 means that JMeter will take 10 seconds to get all the 10 threads up and running. Thread Group element helps to define a performance test scenario in JMeter. a. Ramp-Up Period tells JMeter how long to Step 2) Adding JMeter elements. Where: Number of threads define the number of Users. Add Thread Group to the Test Plan and then add HTTP Request Sampler and entering the Website address in the HTTP Request as shown below. Replace Static Loop Count JMeter Loop Controller View Results Tree First, install Customer Thread Groups from the JMeter Plugins Manager. JMeter Loop Controller If we take a Test Plan that manages the loop count using the Thread Group. Therefore, total iterations are 50. props.put("ITERATION_COUNT", testSequence.size().toString()); And finally assign the size of the testSequence array to a JMeter Property called ITERATION_COUNT. If you set the value to 0, then JMeter will immediately start all of your users. Number of threads: 10, Ramp-Up period: 10 seconds and Loop Count: 1 means that JMeter will take 10 seconds to get all the 10 threads up and running. Thread Iterations Limit: 1. Step 1 :- Right Click Test Plan>Add>Threads (Users) > Thread Group and Set Values as Number of Threads as 100, Ramp-Up Period as 2 and Loop Count value as 3. Hold Target Rate Time (sec): 1. If you enter a loop count value of 1, then JMeter will run your test only once. Each thread will start 1 second (10 divided by 10) after the previous thread was begun. Multiple threads are used to simulate concurrent connections to your server application. Jmeter1001TPS TPSTPS For instance, with 5 users and 5 second Ramp-Up . Add Inter-Thread Communication PreProcessor as a child of the sampler of the Driver thread group and read the value from the FIFO queue into a JMeter Variable This way Driver Thread Group will wait the data from the User Thread Group, you can normally configure as many loops as needed on Thread Group level. JMeter will parse the CSV file and populate those . "Start" This is initial counter value, let's make it 1. Try increasing it. We will be passing thread group user count, ramp-up period, thread group duration information via property files to the test. 100). "Increment" Scheduler checkbox Once selected, the Scheduler Configuration section appears at the bottom of the control panel. b. Loop Count: You can set the number of iterations for each user in the group using Loop Count. In Scenario 1, 10 threads are used, and the ramp-up period is 10 seconds, so JMeter will take 10 seconds to get all 10 threads up and running. To have JMeter repeatedly run your Test Plan, select the Forever checkbox. 06-23-2011, 01:29 AM #3. pratik98293. JMeter Loop Controller Test Plan We will see that each sampler is executed 2 times as this is the number that we configured in the Thread Group. .
