JMeter Timers Primer

Some of the most versatile components in JMeter are timers. Without JMeter timers, elements of a JMeter test plan are executed sequentially without pausing. This can potentially overwhelm your target test application by generating too many requests in a short period of time. In this brief post, we will cover most of the available types of timers that can be used in JMeter test plans. You can find all available timer elements under the “Timers” submenuRead More →

JMeter Videos

RedLine13 has partnered with Pragmatic Test Labs to develop a new series of JMeter videos. Pragmatic Test Labs is a Software Testing company based in Sri Lanka. They provide services ranging from manual E2E testing, test automation to performance testing. Janesh Kodikara is the founder/CEO of Pragmatic Test Labs and an experienced software tester, test automation/JMeter trainer. Janesh has also started JMeter Facebook group to create a platform for performance testers around the world. It currentlyRead More →

JMeter Throughput Controlling

Performance testing is a type of non functional testing intended to determine the responsiveness, throughput, reliability, and/or scalability of a system under a given workload. Throughput is the number of units of work that can be handled per unit of time; for instance, number of requests per second (RPS) , calls per day, hits per second, reports per year, etc.  In this video controlling the throughput is demonstrated. Throughput is a business concern. Throughput can beRead More →

graph-update-users-running

We have updated the Overview Graphs by adding the ability to see the exact number of virtual users currently running at that time period. To support this change, we modified simple and custom languages tests to report when a user starts after the ramp up period: Now with our update, graphs will now give more accurate views of when a virtual user starts the test script:Read More →

From the Open Source Load Testing presentation http://www.slideshare.net/richardfriedman/open-source-load-testing In this slide we will examine load testing where the application is a black-box.  When we run our test on that black box we are looking to expose a performance bottleneck, typically this bottleneck will emerge as either performance or throughput issues. Performance. Measuring the response time of requests or test plans.  Typically measured in ms or s, but it will be specific to your test plans. Throughput.  Measuring theRead More →
