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
AI is getting better in many areas, so why hasn’t it been used much in performance testing? Creating performance test scripts with AI isn’t very hard. The real challenge is instructing AI, exactly what you need, so it gives you the right results. This is where prompt engineering becomes important. In this article, we’ll show … Read more
In Apache JMeter, various types of post-processors are available to capture dynamic values such as session IDs, authentication tokens, or transaction IDs. These post-processors are designed to extract and store data from server responses for use in subsequent requests. These post-processors are: However, ensuring these captured values are correct is critical to avoid test failures … Read more
JMeter Precise Throughput Timer is a goal-oriented element that helps to achieve the desired throughput (Total Number of Requests per unit of time). This timer maintains the throughput throughout the test and achieves the target. Of course, if the server is unable to handle such a load, the throughput will be lower. Throughput may decrease … 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
Apache JMeter is a well-designed tool for load generation. It is a freeware tool decorated with almost all the basic and advanced features of a licensed performance testing tool. But certain features are still unavailable like dynamic pacing. Refer to the article if you want to understand Pacing in detail Currently, we use either Timers … Read more
