JMeter

JMeter Alternatives JMeter is a popular open-source performance testing tool, but there are several alternatives available that offer additional features, better scalability, or different approaches to performance and load testing. 1. Open-Source Alternatives 1.1 Gatling High-performance load testing tool based on Scala. Uses asynchronous architecture for better scalability. Provides detailed graphical reports. Supports scripting via […]

Load Testing Metrics Various metrics help determine how well a system can handle high user traffic and stress conditions when performing load testing. These metrics provide valuable insights into the system’s performance and help identify potential bottlenecks. Some of the important load-testing metrics are as follows: Response Time Response time is the time it takes […]

JMeter Load Testing Features Apache JMeter is a powerful tool for both performance and functional testing of static and dynamic resources, including files, Servlets, Perl scripts, Java objects, databases, queries, FTP servers, and more. It can simulate heavy user loads on servers, networks, or applications to assess their stability, scalability, and overall performance under varying […]

JMeter BeanShell PreProcessor Pre-Processors execute before the sampler runs. They allow you to dynamically manipulate variables, set up preconditions, or modify requests on the fly. BeanShell PreProcessor This pre-processor uses BeanShell scripting (a Java-like language) to run code. It has access to JMeter variables (vars), properties, and logging functions (log). An example of a JMeter […]

JMeter Constant Timer A Constant Timer in JMeter ensures that each thread pauses for the same amount of time between requests. This helps in simulating real-world user behavior where requests are not sent continuously without delay. Add a Constant Timer To apply a timer to a single sampler, we need to add the timer as […]

Running JMeter in Non-GUI Mode JMeter Non-GUI mode is recommended for performance testing as it consumes less memory and runs faster than GUI mode. JMeter Non-GUI Mode is also called as command-line mode. Follow the below steps to run JMeter using command line in Non-GUI mode. Open command prompt Navigate to JMeter’s bin directory Enter the […]
