When performing performance or load testing using Apache JMeter, you sometimes need to go beyond the built-in components to handle complex logic or dynamic behavior. This is where scripting becomes important. JSR223 is a feature in JMeter that allows you to write custom scripts using languages like Groovy, JavaScript, or Jython to enhance your test … Read more
As the name suggested, the JMeter Uniform Random Timer is used to generate and add the random delay in a uniform manner before the execution of a sampler. This timer is based on a random function and generates a random amount of time (delay), with each time interval having the same probability of occurring. Hence it is … Read more
Let’s consider, you run the script in the actual load test and often get an error at a particular step. Now, you want to know the error message coming inside the response body to check what is the root cause of the error. One of the solutions is to add a ‘View Results Tree’ listener … Read more
Just having a knowledge of how to record the script for an application and execute the test; should not be enough for a performance tester. As described in the previous article, performance testing should be realistic rather than just a simple test. To implement this concept, a performance tester should know how does a testing … Read more
In JMeter, BeanShell Listener is a scripting-based listener. It means that you will need to implement the listener logic by yourself using one of the supported scripting languages. Usually, it is helpful when you need to define logic based on your requirement and want to write some unique algorithm which is not currently provided by JMeter. You … Read more
