WHAT IS A PERCENTILE? Percentile (common measurement in statistics) splits the given sample group into 100 equal-sized intervals and this enables the data to be analyzed in terms of percentages. We can explain the usage of percentile with an example: The response time for an HTTP request below which 90% of the response time values lie, is called the 90-percentile response time. In the following graph, 90% of the requests is processed in 3.0 seconds or less: WHY DO WE USE PERCENTILES? If we speak statistically, there are a lot of methods to define just how good of an [...]

By |2021-09-29T13:45:48+03:00January 18th, 2021|Tags: , , , , |

Even though, load testing and performance testing have different meanings in the software world, the basis is the same; to be able to fully answer the following questions. "How does the system behave under a certain load?" "What kind of infrastructure do I need within acceptable values?" "How far does this system take us with these resources?" To get these answers, you must first be able to apply similar loads and see the current behavior of the system. The next step is analysis. What Will We Analyze? The analysis part is very thorough. Because at this point, we also [...]

By |2021-07-01T15:57:25+03:00March 23rd, 2018|Tags: , |

Even though general functionalities of JMeter cover many needs of a performance test, you might need additional scripting. Apache JMeter has the functionality to run Java code snippets during your test execution. BeanShell has access to internal JMeter features and any library located in your JMeter lib folder. BeanShell can be executed as a pre/postcondition or as a sampler. The only difference is that pre/post conditions will not be listed in JMeter Listeners. When using BeanShell, you can use “vars” variable to get and set values generated in the test context. This post will cover those functionalities. BeanShell vars.get() usage [...]

Designing Test Plans with Controllers the Right Way

By |2020-11-17T16:00:40+03:00January 22nd, 2018|Tags: , , |

JMeter Load & Stress testing might seem very straightforward with a little practice, but in big scale projects, things can get complicated. Test plans can be broken, it might be hard to keep the design clean, and it could become a burden for the team to maintain the flow in the long run. So designing test plan is crucial. Like most things in life, the very same rule applies for JMeter: “Simple can be harder than complex” Steve Jobs. To create a well-organized and smoothly maintainable test in the long run, in this article we will focus on JMeter Controllers [...]
