It means that every 1 sec, a new user will be hitting server. In case you want your test to run at a specific time later then you can set the timings as you can also see in the below screenshot. You all must have noticed the “Scheduler” checkbox in above screenshot.It means all 10 users will be hitting servers concurrently as soon as a test is run.Ramp up period defined the amount of time in which the total load will be generated. Ramp Up Period – This field is very important in controlling the load generation.For testing purpose, we should generate only a limited amount of load as generating huge volume at once would mean consuming lot many threads which can ultimately lead to high CPU utilization. Number of Thread(Users) – It defines the number of virtual users.It is very important to configure your thread group as per the test conditions.įor example, if you want to test how a web server behaves when 100 user hits it concurrently, you can set Thread Group as below:īasically, there are three main parameters which must be configured to generate actual load or virtual users: ( Note: Click on any image for enlarged view) Please see below screenshot for adding Thread Groups Just change the name and click anywhere outside the Test Plan window, you would see the name getting changed. You can rename Thread Group name to your own. JMeter is all “Right Click stuff”, you get all the options on the right click. Thread Group can be added to Test Plan by right clicking the test plan.
Thread Group is a group of users which will be hitting the server under test either concurrently or in some predefined sequence. Elements of WorkBench are not saved with Test Plan.For example, If you want to save HTTP Request Sampler with Listener, you can save it as Test Fragment so that it can be used in other test scenarios as well You can also save parts of Test Plan as the different selection.Jmeter files or test plans are saved in form of.The test plan should be saved before running.Therefore, every Test Plan should have virtual users or Thread Group as we call them in JMeter’s terms. Test Plan can be as simple as it could be, with Just ThreadGroup, Sampler, and Listener and it starts getting more complex as soon as you start adding more elements like config elements, preprocessors or controllers.Īs we all know that JMeter measure performance by generating Virtual Users or Threads which hits server under test as if real users are sending requests to a server. Everything which is included in a test plan is executed in a sequence which is top to bottom or as per the defined sequence in the test plan.
#Apache jmeter passing different data for each request software
Just as a simple test plan in Software Testing consists of all steps which execute the script, JMeter’s Test plan has the same purpose. We will work on the most used ones and will take up rest in the next article when we create real time Test Plans. Please note that we won’t be covering all Samplers, listeners in this article. Now we would start touching each component of Jmeter along with use cases just to know how it works and how can testers implement these in their testing. Please refer to the below flow diagram to understand each component and their relation to specific modules of JMeter.
All major components of Jmeter such as Thread Group, Samplers, Listeners and Config Elements are explained in details later in the article.
