Prompt engineering for performance testing involves crafting precise and goal-oriented prompts that effectively assess and evaluate the behavior, reliability, and responsiveness of a system, especially when dealing with AI models, APIs, or software components under various workloads. What is Prompt Engineering? Prompt engineering is the art of writing clear and well-structured instructions (called prompts) so … 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
